Solid state contactor DCS 750
The newly engineered solid state contactor DCS 750 was designed as a non-wearing and maintenance-free alternative to mechanical contactors for railway applications in DC systems. As no maintenance is required, remarkable cost savings will be achieved in high cycling applications .
The solid state contactor DCS can be used in manifold applications such as a load contactor for railway heaters, conditioning devices etc.
In cases where several circuits are required, pre-assembled units may be provided.
Further specifications and information are available on request.
