CH1130 Single Pole High Voltage Contactors

The CH1130 AC and DC high-voltage contactors have been completely revised following the CT series. Permanent magnets and ceramic elements are also used for arc extinguishing in the CH1130. However, without the electromagnets of the CT series, the CH is significantly more compact.

The contactor is used as a precharging contactor in power supply systems or as a main contactor in heating and air conditioning systems.
