Working Mechanism

  • The circuit breaker is connected to an electrical circuit and current flows through the circuit.
  • As the current increases, it passes through a bimetallic strip or an electromagnet in the circuit breaker.
  • When the current exceeds a certain level, the bimetallic strip or electromagnet is triggered, releasing a spring-loaded mechanism that forces a contact arm to open, interrupting the flow of electricity in the circuit.
  • Once the circuit is open, the bimetallic strip or electromagnet cools down, and the contact arm is reset.
  • The circuit breaker can be reset manually by moving the contact arm back to its original position.

Features

  • They have 1 / 2 / 3 pole configuration for connecting multiple connections.
  • These circuit breakers have an operating voltage of 120V / 240V.
  • They are available in amperage ratings ranging from 15 to 100A.
  • These circuit breakers further feature interrupt ratings up to 10kAIC.
  • They have screw terminals for secure connections of the conductor.

Standards and Approvals

  • UL

Frequently Asked Questions

What is the difference between MCCBs and MCBs?

  • MCBs protect items from current overloads, while MCCBs protect equipment from fault currents & excess temperature rise.
  • The tripping circuit of MCBs is fixed, while MCCBs have a movable tripping circuit.
  • MCBs have comparatively low interrupting ratings than MCCBs.

How to install a circuit breaker?

  • Remove the panel cover. Use a screwdriver to unscrew all four edges of the panel cover while holding it tight to prevent it from slipping off.
  • Connect the neutral and ground wires.
  • Place the breaker inside.
  • Screw the panel cover back.

What are the reasons for frequent tripping of the circuit breaker?

A circuit overload, short-circuiting, ground fault surges, defective circuit breaker or an arc fault can cause tripping of the circuit breaker.
