Wide Lineup of General-purpose Solid State
Relays with Applicable Loads of 5 to 90 A
•AC Output Relays with 75-A and 90-A output currents have
been added to the G3NA Series.
•All models feature the same compact dimensions to provide a
uniform mounting pitch.
•Built-in varistor effectively absorbs external surges.
(except G3NA-D210B)
•Operation indicator enables monitoring operation.
•Protective cover for greater safety.
•Standard models certified by UL and CSA and -UTU models by
•The following G3NA Relay models are RoHS Compliant now:
G3NA-205B / 210B / 220B / 225B (-UTU) all input voltage and G3NA-D210B all input voltages.
Effective July 1st, 2010 these G3NA Relay models will be manufactured RoHS Compliant.:

List of Models
*The standard models are certified by UL and CSA. To order a TÜV-certified model, add “-UTU” to the model number.
Note: 1. The applicable load is the value for when the SSR is used with silicon grease applied to the specified heat sink. The applicable load de-
pends on the ambient temperature. Refer to Load Current vs. Ambient Temperature in Engineering Data on page 5.
2. Loss time increases under 75 VAC. (Refer to page 14.) Confirm operation with the actual load.

Note: 1. The input impedance is measured at the maximum value of the rated supply voltage (for example, with the model rated at 100 to 120 VAC,
the input impedance is measured at 120 VAC).
2. With constant current input circuit system. The impedance for the G3NA-2@@ B-UTU is 15 mA max.

4. The Input Impedance for G3NA-240B(-UTU) and G3NA-250B(-UTU) AC100-120 will be 72k Ohms + - 20% for every model manufactured
July 1, 2010 or later.

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.
