remote signaling of alarms and tripping of the circuit breaker.
It is suitable both for the electronic trip units of the 6-series and of the 3-series because it is

This enables the device and measurement data to be visualized without operating the
electronic trip unit of the circuit breaker. The backlit LC display o󹪜ers good readability in
all environments with high resolution or inverted display.
