Carlo Gavazzi Phase, Voltage Monitoring Relay, 3, 3+N Phase, SPDT, 177 → 275V ac, DIN Rail

Monitoring relays from Carlo Gavazzi can also be used as 1-phase or 3- phase over current monitoring relays when connected with MI or MP current transformers.Owing to the built-in latch function, the ON-position of the relay output can be maintained. The red LED indicates the alarm status.
