ARTECHE offers a wide range of relays specially designed to be used in circuit breaker tripping applications.

› Interface between protection and control equipments and HV and/or MV circuit breakers, eliminating risks in case of internal failure of the circuit breaker.

› Trip contacts multiplication, to operate directly on the circuit breaker and transmit the corresponding alarms in a minimum time.

› Trip and lock-out, with electric or hand reset to avoid accidental closing of circuit breakers associated to power transformers, generators or machines.

› The surveillance of the trip circuit, guarantees it is in perfect conditions to allow the trip when it is needed.
