Miniature Circuit Breakers (MCB)
A circuit breaker is an automatically operated electricalswitch designed to protect an electrical circuit from damage caused by excess current, typically resulting from an overload or short circuit. Its basic function is to interrupt current flow after a fault is detected. Unlike a fuse, which operates once and then must be replaced, a circuit breaker can be reset to resume normal operation.

Construction and Features :

  • State of the art design
  • Contact position indicating window (Clear ON-OFF indicator)
  • Three level indications For ON, OFF & TRIP (Under Fault)
  • Rated short circuit capacity: 10000A (10kA)
  • Trip free mechanism
  • High speed and high breaking capacity mechanism
  • Terminal block with safety shutter: It prevents wrong wiring & burning of terminals
  • High speed wiping contact structure
  • Bi-connect terminals at both sides give a choice of using either a busbar or cable to make the connection.
  • Environment-Friendly, Meets the RoHS Compliance defined by the European Standards
  • Power loss values are much lower than the specified values of IS/IEC making it the most energy-efficient MCB

Residual Current Circuit Breaker (RCCB)
Allwin Electric Residual Current Circuit Breaker(RCCB), also known as Earth Leakage Circuit Breaker(ELCB), is designed to cause the opening of contacts to disconnect the load from the supply mains when the residual current is flowing in the circuit. Earth leakage and its associated hazards can be prevented by RCCB. Faulty wires, poorly insulated equipment & incorrect use of an electrical device are the primary elements that may cause leakage of current.

Isolator Switching Devices
Allwin Electric Isolators are perfect companions for ensuring the complete de-energization of the electrical circuits. The isolator ensures that there will be no current at the load side even if impulse voltage appears when the isolator is OFF.
