Littelfuse 202-575-RP Voltage/Phase Monitor Product Description

The 202-200-SP voltage monitor is designed to protect single-phase motors regardless of size. It can be used with 190V-240VAC, 50/60Hz motors to prevent damage caused by incoming power problems.

A unique microcontroller-based voltage-sensing circuit constantly monitors the voltage to detect harmful power line conditions. When a harmful condition is detected, the relay’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.

Littelfuse 202-575-RP Voltage/Phase Monitor Typical Applications

  • Fans
  • Compressors
  • Air Conditioners
  • Heat Pumps
  • Well Pumps
  • Sump Pumps
  • Small Conveyor Motors

Littelfuse 202-575-RP Voltage/Phase Monitor Features

  • Compact, Quick Mounting Design: 1-Screw Mounting Saves Time and Space. Small Footprint Ideal for Assembly into Panels
  • Proprietary Microcontroller Based circuitry: Constant Monitoring of Single-Phase, Low Voltage, High Voltage, Voltage Unbalance, Phase Reversal, Harmful Power Line Conditions
  • Auto-Sensing Wide Voltage Range (202 & 202-RP): Automatically Senses System Voltage Between 90-480VAC. Saves Setup Time
  • Advanced LED Diagnostics: Quick Visual Indicator for Cause of Trip. Led Indications Include: Normal Operation, Restart Delay, Reverse-Phase Trip, Fault
  • Adjustable Trip Delay (202): Prevent Nuisance Tripping Due to Rapidly Fluctuating Power Line Conditions
