MANUALLY OPERATED ROTARY BLADE TYPE DISCONNECT SWITCH

摘要

DISCONNECT SWITCH A three-pole disconnect switch includes a crossbar which is rotatably mounted to a housing and pivots three movable contact blades between opened and closed positions. Each movable contact blade is removably mounted to the crossbar and makes slidable electric contact with a connector. When in its closed position, each movable contact blade makes electrical connection with a stationary line contact. Modular arc chutes are slidably received in mating cavities formed in the housing above each set of contacts and a pair of auxiliary contact cartridges are received in chambers formed in the housing between the main contacts. A trip mechanism is mounted to the side of the housing and couples one end of the crossbar to a manually operated handle.
