Commercial Trucking

Circuit breakers, electronic relays, power and high-voltage relays

Circuit breakers, electronic relays, power and high-voltage relays for safe, reliable and efficient vehicle electrical system

The availability and safety expectations for commercial trucks are constantly increasing.  A shift toward autonomous driving, electric mobility, and fuel efficiency guidelines are changing the electrical design requirements of  trucks.

Keep freight moving with resettable circuit breakers

E-T-A's well-proven resettable automotive circuit breakers replace MINI® and ATO® blade-type fuses, minimize time for trouble-shooting and avoid unnecessary and expensive vehicle downtimes.

Solid state relays, hybrid relays, and smart programmable devices

E-T-A smart devices provide flexible control of loads, like pumps, flasher circuits and other key sub-assemblies.  E-T-A products feature significantly lower power consumption and elimination of switching noise. Diagnostic and monitoring functions like current measurement, voltage monitoring and wire break monitoring are also available.

Electric powertrain protection

For electric drive systems  E-T-A offers a powerful high-voltage contactor with a compact design for electric vehicle applications. The HVR10 combines physical isolation of high voltages via an electromechanical contact and state-of-the-art semiconductor technology.
