Low voltage switches and contactor laboratory

In two separate test cells with a shielded control room a variety of testing such as breaking tests, short-circuit current tests, mechanical and electrical endurance tests can be done. On the secondary side most common voltages are available.

Robots are applied to operate the breakers and contactors for endurance testing, making / breaking or to record its electrical behavior. By use of a booster and a three-phase, full wave bridge rectifier also DC power can be applied.
