Phase or neutral fault monitoring relay

E1YF400V01085
€133.58 (€110.40 tax excl.)
Phase failure, low voltage, loss of neutral on three-phase lines, the relay detects when the voltage on all phases exceeds 85% of the rated voltage and the neutral is present, the R output switches on. When a fault occurs, the relay disconnects. Associated to a contactor or circuit breaker, it allows to protect machinery and installations. Reference:...
