Moulded Case Circuit Breaker

Moulded Case Circuit Breaker

We offer a range of different moulded case circuit breakers. In a nutshell, they are a specific type of electrical protection device. They’re used to protect the electrical circuit from excessive current that may cause an overload or a short circuit. They contain all the necessary components within an insulated moulded case. A moulded case circuit breaker can be used in just about any environment, including residential applications to commercial and industrial systems.

The moulded case circuit breaker provides both overcurrent and short circuit protection for circuits that range from 63H Amps right up to 3000H Amps.

What are they made from?

Generally, they are manufactured using 2 pieces of heavy-duty electrically insulated plastic. These 2 pieces are riveted together to form a case. There are a series of thermal elements and a spring-loaded trigger inside this case.  When the thermal element gets too warm such as from an overcurrent situation, the spring will trip. This then will shut of the electrical circuit.

A circuit breaker is an essential part of every electrical circuit.

What we offer:

The moulded case circuit breakers we offer range from the 63H AMP 3 pole, and 4 pole circuit breaker, 100H AMP 3 pole and 4 pole circuit breaker, right up to the 800H AMP 4 pole circuit breaker.

Each moulded case circuit breaker is of an excellent quality, manufactured to exacting standards.

Benefits of moulded case circuit breakers:

  • They provide high performance in extremely small and compact dimensions.
  • They provide protection to the electrical system if there are any electrical faults or overloads. They do this by immediately interrupting a current that is extremely high due to a line fault or a short circuit.
  • They protect in the event of an overload where the current is higher than the rated value and lasts a longer time than normal.
  • They can be manually switched on and off as needed.
