Trip relays Instantaneous trip relays, whose contacts change instantaneously from the rest position to the working position when the coil is energized. Instantaneous trip relays, whose contacts change instantaneously from the rest agteche to the working position when the coil is energized. Connecting the relay across the trip circuit supply, the equipment is normally energized.

Latching Relays: Arteche – InnoTrans – Product

It uses reference signal from GPS Global Positioning System and features wide variety of outputs and time coding standards. The output contacts change its position if the relay detects a failure in the continuity of the circuit. Auxiliary supply circuit supervision relays Auxiliary relay with four changeover contacts, aimed to areche the failure of trip supply.

Through a small supervision current the whole circuit is supervised, in both positions of the circuit breaker opened or closed. Trip circuit supervision relays For single phase or three phase circuit breakers.

Faults will occur when the trip voltage is lost, so the relay drops off in those cases, providing the related signs and alarms. The correct state of the circuit is showed with a green LED on the front plate of the relay.

wrteche Depending on which coil is energized, the contacts will change from one position to the other. 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 non-permanent failures of trip supply would not be considered.

This range includes relays with 2, 4 and 8 contacts, with operating times from 3 ms to 8 ms, depending on the model. For single phase or three phase circuit breakers. The contacts return to the rest position when the coil is no longer energized.

Trip and lockout relays Trip relays with 2 stable positions for the output contacts.

ARTECHE, Spain

Delays 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. Trip relays with 2 stable positions for the output contacts.

Auxiliary relay with four changeover contacts, aimed to supervise the failure of trip supply.
