A protector trip relay is one of the important devices found in electrical systems. It constantly keeps a watch on electrical parameters and trips a mechanism in case there’s an abnormality. This avoids equipment failure, electric shocks, or hazardous situations besides saving time lost.
Specifications of Crompton 253-PAPW Protector Trip Relay
Crompton 253-PAPW is highly renowned for its performance and the advance features in protecting them from hazardous conditions. Some of its important specifications are:
✅ Voltage & Current Monitoring: The relay will continuously monitor voltage and current levels to prevent both overload and underload conditions.
✅ Phase Failure & Unbalance Protection: It detects the loss of one phase or even phase unbalance, which damages motors and other sensitive equipment.
✅ Time-Delay Settings: Adjustable time delays allow the user to fine-tune their protection settings so that nuisance tripping is avoided while proper fault response is guaranteed.
✅ Compact & Rugged Construction: The relay is designed for industry, and hence has ruggedness which makes it last long.
✅ LED Status Indications: Equipped with LED to indicate operating condition, trip conditions, and system health
