CPP Series Single Pole AC and DC NO and NC Contactors

The CPP series are single pole AC and DC NO and NC contactors up to 1,500 volts and 200 amps.

These extremely compact DC contactors are the smallest switching devices in the power class up to 200 amps and suitable for nominal voltages up to 1,500 volts. The single-pole switching device is available as a universal NO or NC contactor.

They can be used in battery test benches where the devices are ideally suited as integrated or separate precharging contactors for the large Schaltbau CP and CT contactors. Other applications for the NC contactor variant include discharging the capacitor in the DC link of converters in railway vehicles, or in industrial test systems.
