Breaker Control Switches

Breaker Control Switches are used in MV & HV Circuit Breakers typically as Selector Switch for Local Control or Remote Control. This switch is also used for tripping and closing of Circuit breaker with a spring return handle to operate. Lost motion contacts can be cascaded, used for additional protection or for activating annunciator.

Application :

Breaker Control Switches are used in MV, HV & UHV Breakers. They are used as Selector Switches for controlling Locally or Remotely. They are used to Trip or Close the Breakers with momentary contacts
Pistol grip & Wing type Lockable handles available for security & safety
Silver alloy contacts used, have very high durability & endurance.
Cams it suitable for for switching For switching in various programmable combinations.
A double break contact ensures positive making & breaking
Superior insulating material ensures electrical & mechanical stability.
Modular design to achieve any number of poles with minimum components.

Construction : Rotary Cam Switches are modular in design with contact housing stacked with indexing mechanism. The operating knob is attached to steel shaft that rotates the cams which drive the contacts to an unlimited combinations of contact programmes. The housing is made of engineering thermoplastic material contents two sets of contacts. The contacts are mechanically opened 8t are closed using springs that provide force to achieve desirable contact pressure. Two poles can be arranged in each set of contact housing making it compact for the application.
