Monitoring Relays

Phase Loss

Type EQB62DN55%ꢀꢀꢁ

Product Description

3-Phase relay for detection of total or partial phase loss.

Supply range from 208 to 480 VAC.

For mounting on DIN-rail. Housing 17.5mm wide,SPDT relay

output,suitable for back and front panel mounting.

The device detects regenerated voltage up to 85% of the

nominal voltage (phase to phase).
