Phase Sequence Control Relay

TELE
E1PF400VSY01
€127.85 (€105.66 tax excl.)
Three-phase line control relay, this relay detects when all phases are connected in the correct sequence and the asymmetry is less than the adjusted value, the R output relay connects and the yellow LED lights up. As soon as a change occurs in the phase sequence, the output relay disconnects and the yellow LED turns off. Reference: E1PF400VSY01

Phase or neutral failure control relay

TELE
E1YF400V01085
€130.97 (€108.24 tax excl.)
Phase failure, low voltage, neutral loss in three-phase lines, the relay detects when the voltage in all phases exceeds 85% of the rated voltage and the neutral is present, the R output connects. When the defect occurs the relay disconnects. Associated with a contactor or MCB circuit breaker switch allows to protect machinery and installations....
