ATC Phase, Voltage Monitoring Relay, 3 Phase, SPDT

The ATC Phase Monitor Relays offer cost-effective protection against voltage faults in 3 phase systems (Wye or Delta). Designed for ease of use, they are adjustable for voltage, imbalance percentage, and time delay to protect against unbalanced voltages or single phasing.

Power Up 2.5 SEC Minimum
Fault Delay 1 to 25 SEC Adjustable
Severe Fault 1 SEC Phase Loss Unbalance or Phase Reversal
