Undervoltage releases
If there is no voltage present, closing of the breaker is not
possible
If voltage is not applied to the trip unit, operation of the circuit-breaker will result in no-load switching
All undervaltage releases have been designed and tested to fulfill all
applicable requirments in accordence with IEC 60947 ( release voltage 0.70 to 0.35 Ue, response voltage 0.85 to 1.10 Ue

Shunt release
It is used for remote tripping of the circuit-breaker
The coil of the shunt release is designed for short-time operation only
A coil trip is implemented internally
ST coil comes equipped with its dedicated cut-off contact
These devices operate in compliance with IEC 60947 ( tripping voltage 0.70 to 1.10 Ue)

Auxiliary switches (HS) are used for ON and OFF position indication
and control
The alarm switches (AS) are active when the circuit-breaker has been tripped due to an overcurrent e.g. overload or short-circuit
