Selec 800PSR Phase Sequence Relay | 3 Phase Monitoring Relay | Phase Failure Protection Relay

Product Description

The Selec 800PSR Phase Sequence Relay is a compact three-phase monitoring relay designed to protect motors and industrial equipment from phase sequence reversal, phase loss, and voltage imbalance. Continuous monitoring of the incoming three-phase supply helps prevent equipment damage, unexpected downtime, and costly maintenance caused by incorrect phase conditions.

Featuring a wide operating voltage range and DIN rail mounting, the 800PSR is an ideal protection device for motor control centers, automation panels, HVAC systems, pumps, compressors, and other critical three-phase applications.

What is it?

The Selec 800PSR is a phase monitoring relay that continuously checks the health of a three-phase power supply. It detects phase sequence errors, phase failure, and voltage imbalance and disconnects the protected equipment before damage can occur.

Where is it used?

• Motor control centers (MCC Panels)

• Water pumping and booster pump systems

• Air compressors and refrigeration equipment

• HVAC plants and chiller systems

• Industrial machinery and manufacturing equipment

• Conveyor systems and material handling plants
