Introduction

Working Principle

The circuit breaker is an essential device in the modern world, and one of the most important safety mechanisms in your home. Whenever electrical wiring in a building has too much current flowing through it, these simple machines cut the power until somebody can fix the problem. Without circuit breakers (or the alternative, fuses), household electricity would be impractical because of the potential for fires and other mayhem resulting from simple wiring problems and equipment failures.Circuit breakers are essentially resettable fuses that are automatically operated electrical switches that cut off the circuit whenever the current jumps above a safe level, avoiding overheating, melting, and potential fires.

Details

When the overflow of current takes place through MCB – Miniature Circuit Breaker, the bimetallic strip gets heated and it deflects by bending. The deflection of the bi-metallic strip releases a latch. The latch causes the MCB to turn off by stopping the flow of the current in the circuit.

The operating mechanism consists of both magnetic tripping and thermal tripping arrangements.

The magnetic tripping arrangement essentially consists of a composite magnetic system that has a spring loaded dash pot with a magnetic slug in a silicon fluid, and a normal magnetic trip. A current carrying coil in the trip arrangement moves the slug against spring towards a fixed pole piece. So the magnetic pull is developed on the trip lever when there is a sufficient magnetic field produced by the coil.
