ARTECHE, Spain

Trip circuit supervision relays For single phase or three phase circuit breakers. Trip relays with 2 stable positions for the output contacts.

It uses reference signal from GPS Global Positioning System and features wide variety of outputs and time coding standards. Trip and lockout relays Trip relays with 2 stable positions for the output contacts. Auxiliary relay with four changeover contacts, aimed to supervise the failure of trip supply.

Connecting the relay across the trip circuit supply, the equipment is normally energized. Instantaneous trip relays, whose contacts change instantaneously from the rest position to the working position when the coil is energized. Faults will occur when the trip artfche is lost, so the relay drops off in those cases, providing the related signs and alarms.

In order to avoid faulty alarms due to instantaneous supply voltage dips, the drop off time of the relay is delayed over ms so those artedhe failures of trip supply afteche not be considered. Through a small supervision current the whole circuit is supervised, in both positions of the circuit breaker opened or closed. Trip relays Instantaneous trip relays, whose contacts change instantaneously from the rest position to the working position when the coil is energized.

Latching Relays: Arteche – InnoTrans – Product

The correct state of the circuit is showed with a green LED on the front artecche of the relay. This range includes relay with 4 and 8 contacts, with operating times below 8 ms or 10 ms, depending on the model, and possibility of manual reset.

The contacts return to the rest position when the coil is no longer energized. Depending on which coil is energized, the contacts will change from one position to the other. Auxiliary supply relayys supervision relays Auxiliary relay with four changeover contacts, aimed to supervise the failure of trip supply.

For single phase or three phase circuit breakers. This range includes relays with 2, 4 and 8 contacts, with operating times from 3 ms to relayw ms, depending on the model.

The output contacts change its position if the relay detects a failure in the continuity of the circuit.
