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".

© Siemens AG 2016

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.

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

■

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.

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

Configuration and dimensioning

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.

Number of MCBs 1 2 ... 3 4 ... 6 > 7

Correction factor K

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.

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 I

t 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

Configuration and dimensioning

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.

Back-up protection of miniature circuit breakers/fuses

If the maximum short-circuit current of the miniature circuit
breaker at the installation location is unknown, or if the specified
rated switching capacity is exceeded, an additional protective
device must be connected upstream as back-up protection to
prevent overloading of the miniature circuit breaker. This is
usually a fuse.

Back-up protection limit values of miniature circuit breakers/fuses in kA

The following table shows the short-circuit currents – in kA –
up to which back-up protection is guaranteed when using fuses
according to DIN VDE 0636-2 and DIN VDE 0636-3.

Downstream miniature circuit breakers Upstream fuse

Up to the respective Icu according to the table "Rated switching capacity" on page 28.

2)

The values specified for 5SJ4...-.HG.. are not according to UL but are the
manufacturer's specifications according to EN 60947-2 and apply for
voltage U
