AUXILIARY SWITCH

AUXILIARY SWITCH FEATURES Control devices for the circuit breaker play important roles for protecting the power system. It is an auxiliary switch that functions interlocking with the main circuit switching mechanism of the circuit breaker or the insulated switch, therefore high reliability is required. ■Rotary type auxiliary switch ●Cam-operated type B type auxiliary switch Applicable for shutting down relatively large current in frequently switching uses. BMZ and CMZ type auxiliary switches High-reliable auxiliary switches that have higher breaking capacity and higher impact resistance (prevention of chattering) than the conventional ones. All the wiring terminals are located on one side, for making wiring work easier. ●Drum type M type auxiliary switch Compactly designed and yet relatively high in breaking performance; therefore most suitable for miniaturize for the equipment. ■Push-type auxiliary switch ●UX-33A Applicable for a high-voltage electromagnetic contactor or a vacuum circuit breakers. The contact parts has a structure that can be incorporate a magnet, so that it’s possible to increase the breaking capacity of the contacts.
