Glossary

Auxiliary trip unit
Undervoltage releases and shunt releases are available.
BSS module
Breaker Status Sensor - for collecting the information about the status of the circuit breaker
by means of signaling switch, and the transfer of this information to the CubicleBUS.
COM15 module
The communication module is the interface adapter for
● Converting the CubicleBUS signals to PROFIBUS DP signals and vice versa
● Provision of three isolated outputs for control functions (ON, OFF, 1x freely available)
● One input, freely usable for information from the switchgear
● Additional function when used as slide-in circuit breaker:
– Recording the position of the circuit breaker in the guide frame with the signaling
CubicleBUS
Data bus system in the vicinity of the circuit breaker and to the fieldbus (PROFIBUS DP)
Energy transformer
Generates energy (power supply) for the internal supply of the overcurrent release.
Manual connector coding
The manual connectors can be coded to prevent the auxiliary conductor connections from
being connected incorrectly.
Mechanical interlock
This function supports different types of mechanical interlocking for circuit breakers.
Motorized operating mechanism
A geared motor automatically charges the stored-energy spring mechanism as soon as
voltage has been applied to the auxiliary supply connections. After one closing operation, the
stored-energy spring mechanism is automatically charged for the next closing operation.
