Heat sink area (cm2)
Load current (A)
Note: The heat sink area refers to the combined area
of the sides of the heat sink that radiate heat.
For example, when a current of 18 A is allowed
to flow through the SSR at 40°C, the graph
shows that the heat sink area is about 450 cm2.
Therefore, if the heat sink is square, one side of
the heat sink must be 15 cm ( ) or
longer.

Safety Precautions

Safety Precautions
Refer to Safety Precautions for All Solid State Relays.
!CAUTION
Touching the charged section may occasionally cause
minor electric shock. Do not touch the G3NA terminal
section (the charged section) when the power supply
is ON. Be sure to attach the cover before use.
!CAUTION
The G3NA and heat sink will be hot and may
occasionally cause minor burns. Do not touch the
G3NA or the heat sink either while the power supply is
ON, or immediately after the power is turned OFF.
!CAUTION
The internal snubber circuit is charged and may
occasionally cause minor electric shock. Do not touch
the G3NA’s main circuit terminals immediately after
the power is turned OFF.
!CAUTION
Be sure to conduct wiring with the power supply turned
OFF, and always attach the terminal cover after
completing wiring. Touching the terminals when they
are charged may occasionally result in minor electric
shock.
!CAUTION
Do not apply a short-circuit to the load side of the
G3NA. The G3NA may rupture. To protect against
short-circuit accidents, install a protective device, such
as a quick-burning fuse, on the power supply line.
■Precautions for Safe Use
Although OMRON continuously strives to improve the quality and
reliability of our relays, the G3NA contains semiconductors, which
are generally prone to occasional malfunction and failure.
Maintaining safety is particularly difficult if a relay is used outside of
its ratings. Always use the G3NA within the rated values. When using
the G3NA, always design the system to ensure safety and prevent
human accidents, fires, and social damage even in the event of
G3NA failure, including system redundancy, measures to prevent
fires from spreading, and designs to prevent malfunction.
1. G3NA malfunction or fire damage may occasionally occur. Do not
apply excessive voltage or current to the G3NA terminals.
2. Heat Dissipation
•Do not obstruct the airflow to the G3NA or heat sink. Heat
generated from an G3NA error may occasionally cause the
output element to short, or cause fire damage.
•Be sure to prevent the ambient temperature from rising due to
the heat radiation of the G3NA. If the G3NA is mounted inside a
panel, install a fan so that the interior of the panel is fully
ventilated.
•Mount the G3NA in the specified orientation. If the G3NA is
mounted in any other orientation, abnormal heat generation
may cause output elements to short or may cause burning.
•Do not use the G3NA if the heat sink fins are bent, e.g., as the
result of dropping the G3NA. Heat dissipation characteristics will
be reduced, possibly causing G3NA failure.
•Apply a thin layer of Toshiba Silicone’s YG6260 or Sinetsu
Silicone’s G746, or a similar product to the heat sink before
mounting
•If a material with high thermal resistance, such as wood, is
used, heat generated by the G3NA may occasionally cause fire
or burning. When installing the G3NA directly into a control
panel so that the panel can be used as a heat sink, use a panel
material with low thermal resistance, such as aluminum or steel.
•Use the specified heat sink or one with equivalent or better
characteristics.
3. Wire the G3NA and tighten screws correctly, observing the
following precautions
Heat generated by a terminal error may occasionally result in fire
damage. Do not operate if the screws on the output terminal are
loose.
•Abnormal heat generated by wires may occasionally result in
fire damage. Use wires suitable for the load current.
•Abnormal heat generated by terminals may occasionally result
in fire damage. Do not operate if the screws on the output
terminal are loose.
Tightening Torque
•Abnormal heat generated by terminals may occasionally result
in fire damage. When tightening terminal screws, be sure that
no non-conductive foreign matter is caught in screw.
•For GN3A Relays of 40 A or higher, use crimp terminals of an
appropriate size for the wire diameter for M5 terminals.
•Do not use any wires with damaged sheaths. These may cause
electric shock or leakage.
•Do not place wiring in the same conduit or duct as high-voltage
lines. Induction may cause malfunction or damage.
•Use wires of an appropriate length, otherwise malfunction and
damage may result due to induction.
•Mount the DIN Track securely. Otherwise, the DIN Track may
fall.

Operating and Storage Locations
Do not use or store the G3NA in the following locations. Doing so
may result in damage, malfunction, or deterioration of performance
characteristics.
■Precautions for Correct Use
Please observe the following precautions to prevent failure to
operate, malfunction, or undesirable effect on product performance.
Before Actual Operation
1. The G3NA in operation may cause an unexpected accident.
Therefore it is necessary to test the G3NA under the variety of
conditions that are possible. As for the characteristics of the
G3NA, it is necessary to consider differences in characteristics
between individual SSRs.
2. Unless otherwise specified, the ratings in this catalog are tested
values in a temperature range between 15°C and 30°C, a relative
humidity range between 25% and 85%, and an atmospheric
pressure range between 88 and 106 kPa (standard test
conditions according to JIS C5442). It will be necessary to
provide the above conditions as well as the load conditions if the
user wants to confirm the ratings of specific G3NAs.
Mounting Method
SSR Mounting Pitch (Panel Mounting)
Relationship between SSRs and Duct Height
Ventilation Outside the Control Panel
If the air inlet or air outlet has a filter, clean the filter regularly to
prevent it from clogging to ensure an efficient flow of air.
Do not locate any objects around the air inlet or air outlet, otherwise
the objects may obstruct the proper ventilation of the control panel.
A heat exchanger, if used, should be located in front of the SSRs to
ensure the efficiency of the heat exchanger.
•Please reduce the ambient temperature of SSRs.
The rated load current of an SSR is measured at an ambient
temperature of 40°C.
•An SSR uses a semiconductor in the output element. This causes
the temperature inside the control panel to increase due to heating
resulting from the passage of electrical current through the load. To
restrict heating, attach a fan to the ventilation outlet or air inlet of
the control panel to ventilate the panel. This will reduce the ambient
temperature of the SSRs and thus increase reliability. (Generally,
each 10 °C reduction in temperature will double the expected life.)
Example: For 10 SSRs with load currents of 10 A,
0.16 x 10 = 1.6
Thus, 2 fans would be required.
Size of fans: 92 mm2, Air volume: 0.7 m3/min,
Ambient temperature of control panel: 30 °C
If there are other instruments that generate heat in the control panel
other than SSRs, additional ventilation will be required.
•Do not use or store in locations subject to direct sunlight.
•Do not use in locations subject to ambient temperatures outside
the range –20 to 60°C.
•Do not use in locations subject to relative humidity outside the
range 45% to 85% or locations subject to condensation as the
result of severe changes in temperature.
•Do not store in locations subject to ambient temperatures outside
the range –30 to 70°C.
•Do not use or store in locations subject to corrosive or flammable
gases.
•Do not use or store in locations subject to dust (especially iron
dust) or salts.
•Do not use or store in locations subject to shock or vibration.
•Do not use or store in locations subject to exposure to water, oil, or
chemicals.
•Do not use or store in locations subject to high temperatures or
high humidity.
•Do not use or store in locations subject to salt damage.
•Do not use or store in locations subject to rain or water drops.

Preventing Overheating with a High-
capacity Heat Sink (Y92B-P250NF)
•When the High-capacity Heat Sink is used, high-capacity switching
at 75 A or 90 A requires forced cooling with a fan. Connect the Fan
to a power supply according to its ratings specifications.
•If the Fan stops due to a power supply error, due to foreign matter
in the power supply connection, or due to aging, the Heat Sink will
heat to high temperatures, possibly resulting in failure of the SSR or
adverse affects on other devices. Implement an overheating
prevention measure, such as turning OFF the load current, if the
Heat Sink overheats.
•A thermostat is provided to detect overheating. The thermostat
uses a NC contact, i.e., the circuit will be opened for overheating.
This thermostat can be used to stop the operation of the SSR.
Implement an overheating prevention measure by using this signal
to output an alarm or perform another response applicable to the
system. Also, confirm that there is no problem with the overall
system.
•Do not connect the thermostat directly to the load power supply.
Connect it to a contactor or other shutoff device connected above
the SSR.
•Terminals equivalent to Faston #187 are used for the thermostat
terminals.
•Do not place heat-dissipating silicon grease on the thermostat.
•Do not solder the thermostat terminals.
•The following diagram shows a protective circuit example.
Ventilating a High-capacity Heat Sink
(Y92B-P250NF)
•Refer to Ventilation Outside the Control Panel.
Operating Conditions
•Do not apply currents exceeding the rated current otherwise, the
temperature of the G3NA may rise excessively.
•As protection against accidents due to short-circuiting, be sure to
install protective devices, such as fuses and no-fuse breakers, on
the power supply side.
•Do not apply overvoltages to the input circuit or output circuit.
Failure or burning may result.
•Do not drop the G3NA or otherwise subject it to abnormal shock.
Malfunction or failure may result.
•Keep the cooling system running continuously during the ON/OFF
operation of the SSR. This is to allow residual heat to dissipate
while the SSR is OFF. (load current 75 A, 90 A models)
Noise Terminal Voltage According to
EN55011
1. The G3NA-UTU complies with EN55011 standards when a
capacitor is connected to the load power supply as shown in the
following circuit diagram.
•Connect capacitor C1 to both sides of the input terminals for a
G3NA with a DC input.
•Connect capacitor C2 to both sides of the load power supply
output.
•Connect the varistor to both sides of the G3NA output terminals.
•Do not use an input line that is longer than 3 m.
2. DC-switching models comply with EMC Directives under the
following conditions ("-UTU" models only).
•The input cable must be less than 3 m.
Loss Time
The loss time will increase when the G3NA is used at a low applied
voltage or current. Be sure that this does not cause any problems.
Using DC Loads
For a DC or L load, a diode should be connected in parallel the load
to absorb the counter electromotive force of the load.
Fuses
Connect a quick-break fuse in series with the load as a short-circuit
protection measure. Use one of the fuses in the following table or
one with equivalent or better characteristics.
Recommended Fuses
Reverse Connection
The output terminal side of the G3NA-D210B is connected to a built-
in diode to protect the SSR from damage that may result from
reverse connection. The SSR, however, cannot withstand one minute
or more if the wires are connected in reverse. Therefore, pay the
utmost attention not to make polarity mistakes on the load side.

■Precautions on Operating and Storage Environments
1. Operating Ambient Temperature
The rated value for the ambient operating temperature of the G3NA
is for when there is no heat build-up. For this reason, under
conditions where heat dissipation is not good due to poor ventilation,
and where heat may build up easily, the actual temperature of the
G3NA may exceed the rated value resulting in malfunction or
burning.
When using the G3NA, design the system to allow heat dissipation
sufficient to stay below the Load Current vs. Ambient Temperature
characteristic curve. Note also that the ambient temperature of the
G3NA may increase as a result of environmental conditions (e.g.,
climate or air-conditioning) and operating conditions (e.g., mounting
in an airtight panel).
2. Transportation
When transporting the G3NA, observe the following points. Not doing
so may result in damage, malfunction, or deterioration of
performance characteristics.
•Do not drop the G3NA or subject it to severe vibration or shock.
•Do not transport the G3NA if it is wet.
•Do not transport the G3NA under high temperatures or humidity.
•Do not transport the G3NA without packing it properly.
3. Vibration and Shock
Do not subject the G3NA to excessive vibration or shock. Otherwise
the G3NA may malfunction and internal components may be
deformed or damaged, resulting in failure of the G3NA to operate.
To prevent the G3NA from abnormal vibration, do not install the
G3NA in locations or by means that will subject it to vibration from
other devices, such as motors.
4. Solvents
Do not allow the G3NA or the resin portion of the Fan’s thermostat to
come in contact with solvents, such as thinners or gasoline. Doing so
will dissolve the markings on the G3NA.
5. Oil
Do not allow the G3NA terminal cover to come in contact with oil.
Doing so will cause the cover to crack and become cloudy.
■Operation
1. Leakage Current
A leakage current flows through a snubber circuit in the G3NA even
when there is no power input. Therefore, always turn OFF the power
to the input or load and check that it is safe before replacing or wiring
the G3NA.
2. Screw Tightening Torque
Tighten the G3NA terminal screws properly. If the screws are not
tight, the G3NA will be damaged by heat generated when the power
is ON. Perform wiring using the specified tightening torque.
3. Handling Relays
Do not mount the G3NA when your hands are oily or dirty, e.g., with
metal powder. These may cause G3NA failure.
4. Do Not Drop
Be careful not to drop a Relay or Heat Sink onto any part of your
body while working. Injury may result. This is particularly true for the
High-capacity Heat Sink (Y92B-P250NF), which weighs 2.5 kg.
