What we are looking for

Circuit Breakers, Power Relays & SSRPCs for the Commercial Vehicle Industry

Are you looking for protection solutions, reaching from standard products to customer-specific components and system solutions to joint design projects? E-T-A products especially for tough environments like agricultural, forestry and construction equipment, provides professional protection solutions for all loads in off road vehicle.

Electronic relays minimise power loss through low control currents and reduce stand-by current input. The purely electronic design without moving contacts ensures wear-free switching function.

Power relays reliably separate single-pole loads up to 300 A, e.g. for battery isolation or disconnection of the heavy load circuits.
