Com190 Communication Module - Siemens SENTRON 3WA System Manual

Requirements
Communication via the CubicleBus² requires the following hardware components:
• 3WA air circuit breaker
• ETU600 electronic trip unit
• Terminating resistor (120 Ω)
• Optional CubicleBUS
Note
Compatibility with legacy product
The CubicleBUS² applied in the 3WA circuit breaker is an enhanced development of the
CubicleBUS system applied in the 3WL circuit breaker. They are not compatible with each
other.

The COM190 is the communication module for the 3WA circuit breaker. It forms part of the
CubicleBUS
nodes, e.g.:
• Readout of circuit breaker data and metering values
• Readout of circuit breaker status
• Transfer of alarms and warnings
• Setting of parameters
• Closing and opening of circuit breaker via the communication interface
