The trip relay (defined with the acronym K94 in the ANSI standards) is a fast-acting relay designed to ensure a high switching speed together with a high breaking capacity in order to manage inductive and high direct current loads.Read more
The concept of contact resistance may, on the surface, seems very simple, especially when it comes to the contact resistance of an electromechanical relays.
However, the contact resistance is the sum of multiple resistance values, each influenced by several very different physical variables.Read more

Announcing the creation of a new series of instantaneous multi-pole relays from the MTI line, featuring more compact dimensions than the previous series.
Available in a monostable and bistable versions, with 8 changeover contacts.
Suitable for use in the most demanding applications.
AMRA is proud for the trust of REE, RED ELECTRICA DE ESPANA!
It’s another demonstration of the quality of our products, already approved by the most important European operators for the use in the heavy or intensive duty such as HV electrical substations.
The new TMM multifunction timer relays regroup in only one component the functions of timing more request.
Wide range of time setting, high immunity to EMC disturbances.
Suitable for rolling stock applications.
Equipped by SPRING connections, with high tearing resistance, the PRIR series allow quick and easy wiring, saving over 50% of the time compared to traditional wiring.
Can be used with the AMRA line relays and with many of the AMRA-MTI line, the PRIR series joins the PAIR series, with front connection.Read more
CHAUVIN ARNOUX Group relays were chosen by EDF-CIH France for the modernization of the automation and control systems of the hydroelectric plants on the national territory.
It’s another demonstration of the quality of our products, already approved by the most important European operators for the use in the heavy or intensive duty such as power plant and HV electrical substations.
