Phase sequence control relay

TELE
E1PF400VSY01
€139.37 (€114.24 tax excl.)
Control relay on three-phase lines, this relay detects when all phases are connected in the correct sequence and the asymmetry is less than the set value, the output relay R switches on and the yellow LED lights up. As soon as the phase sequence changes, the output relay switches off and the yellow LED goes out. Art. no.: E1PF400VSY01Picture is...

Phase or neutral fault monitoring relay

TELE
E1YF400V01085
€142.78 (€117.03 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:...
