Trip, supervision and auxiliary relays

Our offering includes a complete range of auxiliary, trip, lockout and contactor relays specially designed for the most demanding environments. Millions of Arteche power relays are in service worldwide.

How Electrical Relays Work

A relay is an electromagnetic switch that opens and closes circuits electromechanically or electronically. A relatively small electric current that can turn on or off a much larger electric current operates a relay.

The essentials of necessary auxiliary relays in tripping and control

Auxiliary relays with four changeover contacts are aimed to supervise the failure of trip supply. Connecting the relay across the trip circuit supply, the equipment is normally energized.

Master Trip Relay 86-Lock Out relay working Function

The Master Trip Relay is designed as a high-speed auxiliary tripping relay, capable of issuing a trip command to the circuit breaker''s trip coil almost instantaneously.
