1 pole NO contactor for 1,200 A thermal current and 3,000 V nominal voltage with integreated pre-charging contactor
CP – Modular and compact switchgear
1 pole bi-directional high-voltage contactors, disconnectors, changeover switches for DC and AC for power converters. Rated insulation voltage up to 4,800 V, continuous thermal current up to 2,000 A.
With the CP series Schaltbau is introducing once more an innovative concept to the switchgear market. The arc-handling is done exclusively by permanent-magnetic blowout. This patented technology ensures fully bi-directional breaking capability and a more compact design. By reducing dimensions and weight we save you valuable space.
For the first time the universal devices can be configured as NO/NC contactor, disconnector or changeover switch. This enables us to react flexibly to changing customer requirements. The high switching functionality and reliability ensure practical and cost effective operation.
The combination of innovative technology, compact design and high versatility makes the CP power contactors particularly suitable for use in railway and industrial applications. Thanks to its unique modular design, the new product family includes a variety of possible configurations catering to a wide range of applications.

A product tailored to your needs
Find your ideal switching device and configure it as NO/NC contactor, disconnector or changeover switch
Maximum modularity – whether as a contactor, disconnect switch or changeover switch: The CP series offers countless variation options and is the perfect fit for your application. A scalable power interface in combination with different extinguishing chambers according to the switching requirements make the switchgear universally applicable.
In addition to various auxiliary switch groups, a high-voltage discharge contact and/or a precharging contactor can also be integrated.
