Introduction

Working Principle

During short circuit condition, the current rises suddenly, causing electromechanical displacement of plunger associated with a tripping coil or solenoid. The plunger strikes the trip lever causing immediate release of latch mechanism consequently open the circuit breaker contacts. This was a simple explanation of a miniature circuit breaker working principle.

The most important thing that Circuit Breaker is doing is to safely and reliably switches off electrical circuit during abnormal conditions of the network, that means over load condition as well as faulty condition.

Details

The XMC45M MCB Magnetic Tripping Mechanism consists of coil, yoke, iron core, fix contact, braided wire, terminal, and bimetallic sheet.

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 dashpot 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.

In case of short circuits or heavy overloads, strong magnetic field produced by the coils (Solenoid) is sufficient to attract the armature of the trip lever irrespective of the position of the slug in the dashpot.
