Crouzet Monitoring Relay, 3 Phase, 183 to 528 V ac Monitor Range, SPDT, DIN Rail, 208V ac, 480 V ac

Description

Multi Function Phase Control Relays 17.5mm – C-Lynx

3 phase network control relays monitor: the correct sequence of phases L1, L2, L3, the total phase failure – Undervoltage and overvoltage from 2% to 20% of Under Voltage Relay and Asymmetry rate from 5% to 15% of Under Voltage Relay. LEDs are used for fault signalling, if a fault persists for longer than the threshold crossing delay configured by the operator, the output relay opens and the LED R is extinguished.
