Miniature Circuit Breakers
■
Overview
The Siemens mounting concept supports the combination of all
5ST3 additional components with Siemens 5SY and 5SP
miniature circuit breakers and with 5SU1 RCBOs.
5SL and 5SY60.. miniature circuit breakers are suitable for
mounting auxiliary switches and fault signal contacts. Auxiliary
switches can also be mounted on 5TE8 flush-mounting circuit
breakers and 5SG71 MINIZED switch disconnectors.
Auxiliary switches (AS)
The auxiliary switch (AS) always signals the contact position of
the miniature circuit breaker, regardless of whether the miniature
circuit breaker was tripped manually or as the result of a fault. An
additional version is also available for the switching of small
currents and voltages for the control of programmable control
systems (PLCs) acc. to EN 61131-2. The auxiliary switch with
test button enables the testing of control circuits without the
need to switch the miniature circuit breaker.
Fault signal contacts (FC)
The fault signal contact (FC) signals the automatic tripping of the
miniature circuit breaker in the event of a fault, such as an
overload or a short circuit. If the fault signal contact is activated,
the contact position does not change if the miniature circuit
breaker is tripped manually. Fault signal contacts with TEST and
RESET buttons enable the testing of control circuits without the
need to trip the miniature circuit breaker. The red RESET button
integrated in the handle also indicates the automatic tripping of
the MCB. The signal can be acknowledged manually using the
RESET button.
Shunt trips (ST)
Shunt trips are used for the remote tripping of a miniature circuit
breaker.
Undervoltage releases (UR)
Undervoltage releases are integrated (e.g. in EMERGENCY-OFF
loops), thus ensuring that the MCB trips in the event of an
emergency, which, in turn, ensures disconnection of the control
circuit according to EN 60204. In the event that the voltage is
interrupted or too low, it also trips, i.e. prevents activation of the
MCB.
Remote controlled mechanisms (RC)
Remote controlled mechanisms are used for the remote ON/OFF
switching of miniature circuit breakers and the remote ON
switching of RC units, as well as the local manual switching of
these devices. A blocking function permits maintenance work. In
the event that a miniature circuit breaker or RC unit is tripped, an
acknowledgment must be carried out prior to switching back on.
The remote controlled mechanism has an operating mode
selector switch with the functions: "Locked", "Manual" and
"Remote Switching".
Selector switch position:
OFF: The remote controlled mechanism is switched off, blocked
mechanically and can be sealed and/or locked.
RC OFF: Only manual operation is possible.
RC ON: Both manual and remote operation are possible.
In the event that a device is tripped by a fault (RC units, miniature
circuit breakers), the handle of the basic device and remote
controlled mechanism switches to the OFF position. The
operator must then acknowledge the tripping by resetting the
remote controlled mechanism (OFF command) before it can be
reactivated. This serves the safety of the installation or to protect
personnel during maintenance work.
In an RC unit/miniature circuit breaker combination, the RC unit
is switched on asynchronously, i.e. prior to the miniature circuit
breaker. The RC units for 5SY and 5SP4 can be switched ON via
the MCB handle jumper using the supplied actuator attachment.
There is no need to switch off the RC unit via the remote
controlled mechanism as the MCB contacts ensure
disconnection of the electrical circuit.
The switching frequency is max. 2 actuations per minute. If this
actuation frequency is exceeded it may cause internal tripping
of the remote controlled mechanism as a protection against
possible overload. In this case, the remote controlled
mechanism must be switched OFF at the function selector
switch and not switched back on again for at least 5 minutes.
More additional 5ST3 ... components, such as AS, FC, ST and
UR, can be added to the right-hand side of the remote controlled
mechanism in line with the Siemens mounting concept.
RC units
RC units can be combined with miniature circuit breakers of
characteristic A, B, C and D. They then form a combination of
RCCB and MCB for personnel, fire and line protection. The
combinations can be tailored to meet individual requirements.
For information on RC units, see chapter "Residual Current
Protective Devices / Arc Fault Detection Devices (AFDDs)" in
Catalog LV 10.

Busbars
5ST standard busbars
■
Overview
The busbar system with pin-type connections can be used for all
5SL6, 5SJ6 ...-.KS and 5SY miniature circuit breakerswith or
without mounted auxiliary switch (AS) or fault signal
contact (FC).
Busbars in 10 mm
2
and 16 mm
2
versions are available.
With bars that can be cut to length, the 5ST37 busbar system
can be tailored to any requirements.
The extremely flexible 5ST36 busbar system with fixed lengths
also enables installation in any length as the busbars can be
overlapped.
No further need for time-consuming tasks, such as cutting,
cutting to length, deburring, cleaning of cut surfaces and
mounting of end caps.
Any free pins on the busbars can be made safe by covering with
touch protection.
Further information on the bus-mounting of miniature circuit
breakers with residual current operated circuit breakers, see
chapter "Residual Current Protective Devices / Arc Fault
Detection Devices (AFDDs)" in Catalog LV 10.

5ST3 busbars acc. to UL 508
■
Overview
Products according to UL standards are used in North America,
but also in several other countries. This is important in particular
for exporting machines or electrical switchgear assemblies and
equipment to the USA. Acceptance and delivery are possible
only if the relevant UL standards are satisfied.
The 5ST37 busbar system according to UL 508 and CSA is
suitable for both universal use worldwide with all 5SY and 5SP
miniature circuit breakers for "Supplementary Protection"
certified according to UL 1077 and for 3NW and 3NC fuse
holders certified according to UL 512. Not approved for use in
feeder circuits.
The busbars are available in single-, two- and three-phase
versions with different pin spacings and with two cross-sections
18 mm² and 25 mm². Infeed can be directly into the terminals of
the miniature circuit breaker or through connection terminals.
The connection terminals are available in two versions – for
direct infeed at the busbar or for infeed directly at the miniature
circuit breaker/fuse holder. Pins that are not required can be
covered with touch protection covers.

SIKclip wiring system
Miniature Circuit Breakers
Busbars
■
Overview
SIKclip is a fast wiring system that simplifies the connection of
control switches:
• For mounting directly on the rear vertical CU busbar system
• Mounting via brackets on the rear of the DIN rail
The 4-pole busbar can handle loads of up to 250 A, each
individual contact up to 63 A.
High degree of protection because each contact is locked
individually.
SIKclip is made of thermoplastic acc. to IEC 60439-3 and is
suitable for high thermal loads.
Note:
To install the SIKclip wiring system in the ALPHA AS, the busbars
must be installed in a vertical rear position, but not recessed. If
the busbars are in a recessed position the cables will not reach
the circuit breakers.

Miniature Circuit Breakers
Correction factors for rated current if bundling
If more than one electrical circuit is loaded in a series of
miniature circuit breakers the resulting increase in ambient
temperature affects the characteristic curve. In this case an
additional correction factor, specific to the rated current of the
miniature circuit breaker, must be taken into account.
Correction factors for rated current at different frequencies
The tripping characteristic applies to a frequency of 50 Hz to
60 Hz. In the case of other frequencies, the following correction
factors must be taken into account.
In the overrange, the limits of the characteristic curves
correspond to the correction factors of the thermal tripping
operation. In the event of a short-circuit, the limits of the
characteristic curves correspond to the correction factors of the
magnetic tripping operation.

Miniature Circuit Breakers
Configuration and dimensioning
Selectivity of miniature circuit breakers/fuses
Distribution systems are usually set up as radial networks. An
overcurrent protection device is required for each reduction of
the conductor cross-section. This produces a series connection
staggered according to rated currents, which should, if possible,
be "selective".
Selectivity means that, in the event of a fault, only the protective
device that is directly next to the fault in the current circuit is
tripped. This means that current paths in parallel can maintain a
power flow.
In the case of miniature circuit breakers with upstream fuses, the
selectivity limit depends largely on the current limitation and
tripping characteristics of the miniature circuit breaker and the
melting I2t value of the fuse.
This produces different selectivity limits for miniature circuit
breakers with different characteristics and rated breaking
capacity.
The following tables provide information on the short-circuit
currents up to which selectivity exists between miniature circuit
breakers and upstream fuses according to DIN VDE 0636-2. The
values specified in kA are limit values that were determined
under unfavorable test conditions. Under normal practical
conditions, you can often expect considerably better values,
depending on the upstream fuses.
In the event of a short-circuit, there is selectivity between the
5SY4, 5SY7, 5SP4, 5SJ4...-.HG.. miniature circuit breakers and
melting fuses according to DIN VDE 0636-2 up to the specified
values in kA.

Miniature Circuit Breakers
Selectivity of miniature circuit breakers/circuit breakers
Distribution systems can also be set up without fuses. In such
cases, a circuit breaker acts as an upstream protective device.
In this case, the selectivity limit depends on the level of peak
current Î let through by the miniature circuit breaker and the
tripping current of the circuit breaker.
The following tables show the short-circuit current in kA up to
which selectivity is guaranteed between miniature circuit
breakers and upstream circuit breakers according to
IEC/EN 60947-2 at 230/400 V AC, 50 Hz.
