CPD - precharge Contactors
The CPD series contactors are typically designed for filter pre-load. They utilize the Permanent Magnets technology and multiple contact arc interruption scheme. In this way the separate arc chute has been definitively eliminated . The result is a very simple, compact and robust contactor, able to meet lifetime requirements without need of maintenance.
Horizontally or vertically mounted, completely insulated from ground, it can be easily installed in converter panels or cubicles.
The standard low voltage interface connector can be removed for customized solution, as in the preparation of pre-assembled unit for pre-charge and insulation purposes.
Its particularly linear shape and the absence of a standard arc-chute allow, in certain cases, to install the resistance of the pre-charge directly above the contactor, in order to create an extremely compact unit, by minimal cabling.
