Swj1 Electronic Multi-function Protect Relay Series

The master circuit SWJ1 Electronic Multi-function Protect Relay Series (called hereinafter referred to as relay) adopts holing type, which does not only get rid of contact line, but also avoid the contact heat with contact terminal. The relay and AC contactor are connected with magnetic force start system, offering reliable protection to loss of phase start, loss of phase operation, locked rotor, overload, abrasion, three-phase unbalanced, and indicating fault type for electric motor.

Product Character:
Monitoring and controlling the current, voltage and temperature together; precise of tuning; high precision of repeat; reaction quick; clear fault indication; more simple installation debugging.

Product function:
Over current 9over load)protection; three-phase unbalanced protection; less phase protection, over voltage protection; under voltage protection; earthing(residual current)protection: fault type indication function; fault memory function; automatic manual reset function; self-check function; fault alarm function; automatic exit for invalidation.
