Schaltbau : wide range of AC or DC contactors up to 1,500 volts rated insulation voltage and 320 A continuous current are based on the modular C195 range. The C195 X can switch DC voltage bidirectionally. It possesses blowout magnets and an electric arc arcing chamber. The bistable designs do not use any current in continuous operation and prevent the deep discharge of battery systems.

The magnetic drive of all designs can activated using voltages of 24 to 110 volts DC. Two S870 snap-action switches report the switch state of the main contacts to the higher-level control system.

AC and DC contactors of the C195 series can frequently switch loads. Developed for use in rail carriages, they also work in extreme ambient temperatures.
