Power relays


Power relays are reliable problem solvers when it comes to switching high currents. Particularly construction machinery, agricultural vehicles as well as buses and trucks, floor-borne vehicles and other special vehicles (e.g. fire brigades) often have connected large electrical loads. In these applications, power relays disconnect the entire on-board electrical system from the battery.

Technical design

Depending on the application, E-T-A offers purely electro-mechanical relays, solid state relays and also a hybrid design consisting of an electro-mechanical switching system with an intelligent electronic control unit.
