Description
800PSR, a protection relay from Selec. 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.
