Phase Voltage Monitor

Part Number:

Description

The MotorSaver® 460 is a 3-phase voltage monitor that protects

190 480VAC or 475 600V, 50/60Hz motors regardless of size.

The product provides a user selectable nominal voltage setpoint and the voltage monitor automatically senses line voltage.

This unique microcontroller-based voltage and phase-sensing device constantly monitors the 3-phase voltages to detect harmful power line conditions such as low, high, and unbalanced voltage, loss of any phase, and phase reversal.

When a harmful condition is detected, the 460 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 and restart delays prevent nuisance tripping due to rapidly fluctuating power line conditions.

All 460 models feature adjustable 1 30 second trip delay, 1 500 second restart delay, 2 8% voltage unbalance trip point, and one form C contact except where noted.

Features

Auto-sensing wide voltage range

Automatically senses system voltage between 190 480VAC or 475 600VAC

Adjustable trip & restart delay settings

Prevent nuisance tripping due to rapidly fluctuating power line conditions

Microcontroller based circuitry
