PMV50A575 - LOVATO - Monitoring Relay - SPDT Contacts, 380 - 575 V ac

– Voltage monitoring relay for phase loss, incorrect phase sequence, minimum and maximum voltage control;
powered by the monitored voltage
– 4 programmable rated voltages for PMV50 A240: 208-220-230-240VAC
– 8 programmable rated voltages for PMV50 A575: 380-400-415-440-460-480-525-575VAC
– Excellent tripping accuracy
– TRMS measurements (True Root Mean Square value)
– Control of phase-to-phase voltages
– Detection of phase loss if one of the voltages is <70% rated value
– Tripping time for phase loss: 60ms
