Contactors

The contactors are intended for switching DC circuits of traction vehicles under load. Design of the contactors is modular which enables the operator to create unified ranges with variable parameters. The contactors are actuated by pneumatic drive with electromagnetic valve (pneumatic) or by electromagnet (electromagnetic). The contactors are air contactors with electromagnetic blow out of the arc. In order to cut off the peak voltage, the contactors are equipped by either varistor or diode.

Compliant with EN 60077-1 and 60077-2, EN 61373.

Benefits for you
