What is a magnetic trip breaker?

The magnetic trip portion is used for short circuit (instantaneous) protection. Its action is achieved with an electromagnet whose series with the load short circuit current occurs, passing through the conductor causes the electromagnet’s magnetic field to rapidly increase, attracting the armature and causing the circuit breaker to trip.

Is circuit breaker a good protection device?

Circuit breaker is very effective protection device in any lighting application. Improper loading of MCB might lead to “Nuisance Tripping”, damage the application or damage the circuit breaker and even cause fire breakout. This document will drive you through the brief introduction of circuit breaker, its operation and load calculations.

What is a circuit breaker?

Definitions vary definition. NEMA Definition: A c rcuit breaker is defined in NEMA designed to open and close a circuit by circuit automatically on a predetermined properly applied within its rating. The rigid circuit breaker components can be mounted the circuit breaker.

What does a trip unit do in a circuit breaker?

The trip unit’s function is to trip the overload or short circuit. The key to a circuit breaker’s short circuit control an arc. Every half cycle, an alternating current __________ __________. If the dielectric strength of the contacts will be overpowered and an arc will continue.

What is the difference between MCB trip unit and circuit breaker?

trip unit is temperature sensitive and the magnetic trip unit is current sensitive. These thermal and magnetic trip units are independent and act mechanically with the MCB trip mechanism to open the MCB contacts.
