RELAY;INDUSTRIAL 600V AC MAX 10 AMP MAX

GENERAL PURPOSE 240V AC MAX 10 AMP MAX

The Model 102A is an auto-ranging voltage monitor designed to protect
3-phase motors regardless of size. It is used on 190-480 VAC; 50 to 60
Hz motors to prevent damage caused by single phasing; low voltage;
phase reversal; or voltage unbalance.
This unique microcontroller-based voltage and phase-sensing circuit
constantly monitors the three-phase voltages to detect harmful power
line conditions. When a harmful condition is detected; the MotorSaver’s
output relay is deactivated after a specified trip delay. The output relay
reactivates after power line conditions return to an acceptable level for a
specified amount of time (Restart Delay). The trip delay prevents
nuisance tripping due to rapidly fluctuating power line conditions.
