Phase Failure Relays P1 Pfs2

We commence our business operation as a renowned distributor and supplier of Phase Failure Relays P1 PFS2 in Pune, Maharashtra, India. The Phase Failure Relay is a phase-voltage-balance monitoring device designed for use with magnetic controls to automatically prevent three phase motors or other equipment from operating or attempting to start up under open phase or single-phase conditions, thereby eliminating burnouts and consequent down-time frequently incurred by phase failure.

Phase Failure Relay is not a thermal device. It operates on the principle of phase voltage unbalance which may occur in a three phase system. It also protects against phase loss. All Phase Failure Relay models are listed with Underwriter Laboratories.
