4.11.6 Ready4COM thanks to BSS200 Breaker Status Sensor for ETU600
4.11.6.1 Description
The 3WA circuit breaker obtains the "ready4COM" feature thanks to the BSS200 Breaker
Status Sensor.
The BSS200 Breaker Status Sensor forms part of every circuit breaker with the ETU600
electronic trip unit with the "ready4COM" application package and metering function
PMF-I to PMF-III.
The BSS200 Breaker Status Sensor collects information about status states of the circuit
breaker with the signaling switch and transmits it to the CubicleBUS². In addition, it
controls the communication-capable CC-COM closing coil and the ST-COM shunt trip in
a circuit breaker with the ready4COM feature.
