Protection Relays

Voltage Monitoring Relays

460-XXX-SP SERIES

Single-phase voltage monitor

Description

The 460-100-SP is used on 95–120 V ac, 50*/60 Hz single-phase

motors and the 460-200-SP is used on 190–240 V ac, 50*/60 Hz

single-phase motors to protect them from damaging high and

low voltage conditions. An adjustment knob allows the user to

set a 1–500 second restart delay. The variable restart delay is

also a power-up delay and can be utilized to stagger-start motors

on the same system.

A unique microcontroller-based, voltage-sensing circuit

constantly monitors the voltage 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 and a speciﬁed amount of time has

elapsed (restart delay). The trip delay prevents nuisance tripping

due to rapidly ﬂuctuating power line conditions.
