1 pole bi-directional high-voltage contactors, disconnectors, changeover switches for DC and AC

posted in: News | 0

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 versa- tility 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.
