See communication manual for relay details.
- AO: Analog output module
- BSS: Breaker Status Sensor for acquisition of signals about the circuit breaker status (always combined with COM module)
- c: Internal bus system for interconnection of circuit breaker components and for connection of external c
modules
- COM15/16/35: Communications modules to connect breaker-internal CubicleBUS to external supervisory systems via 
PROFIBUS-DP, Modbus RTU, PROFINET IO or Modbus TCP. Always combined with the BSS (Breaker Status Sensor).
- DI: Digital input module for capturing the status of ungrounded (potential-free) status signals for the purpose of communicating
them or switching active parameter set (ETU776). A maximum of 2 modules in different configurations can be connected.
- DO: Digital output modules with 6 outputs each; a maximum of three modules with different configurations or versions can be
connected
- ETU: Electronic trip unit
- Metering: Metering function or metering function PLUS
- Modbus TCP: Fieldbus for connection of energy management systems and automation systems
- Open / Close: Opening coil and closing coil for opening and closing the circuit breaker via communication
- PROFIBUS DP/PROFINET IO: Field bus for connection of automation components
- Protection: Protection module
- TD400: Test Device; adapter for parameterizing, operating and monitoring the circuit breaker via powerconfig
- VT: Voltage transformer
- ZSI: Module for zone selective interlocking, must always be connected as the first module
NOTE
The basic functions of the electronic trip units do not require an auxiliary power supply.
To use extended functions of the trip units requiring data exchange via the c, an external 24 V DC voltage supply 
 (page 9-98)
must be connected.
