Although it's very unlikely (thankfully!!), if anything went wrong whenever you flick a switch or connect to an electric appliance, there must be some security included as regards the system. This is where moulded case circuit breakers come in aid. They cover things, and if something is wrong they trip the power. Moulded case circuit breakers are commonly installed in homes where people live, offices where work is done and even factories that produce things.
Factories need hundreds of switches capable carrying tens of amperes. The earner works in conditions that are usually far from the best, and appliances often operate under very difficult terms. Safe and lasting, they are an ideal choice for factories fitted with moulded case switches. They generally stay long, with a low failure rate (no outage), and they typically thrive even under harsh conditions i.e. hot climates or can survice dust-prone areas etc
MCCB ( Moulded Case Circuit Breaker) — All parts of the MCCB operating to protect your Electrical System The main part is a handle which you will use for On and Off; contacts allows electric flow same way as water in pipes flowing, trip unit if it detects high current or some equipment drawing more power from another phase than provided at distribution system installation time And also has housing around all these components provides external protection – no one inside can be injured by internals. This help to prevent any accident and also safeguard other devices as well these assemble work together that if the power is extra then it cuts off the supply.
Therefore, you need to consider not only the mechanical strength of a moulded case circuit breaker but how it will work too when choosing one. Fairly simply, the enclosure is that hard outer layer of a switch whereas everything on the inside gets protected and shielded from nasty elements like particles/moisture being introduced by some outside force. These enclosures usually exist as: Moulded Case — These are largely in plastic (in ABS, polycarbonate), diecast metallic or rubber. The switch which is made out of a dense and proper stuff will work according to the place where it would be placed thus relevant material choice is imperative.
Highly common types of moulded case circuit breakers are presented below along with their uses in the list. It is important to choose the one according to your electricity needs. When selecting a circuit breaker, the voltage and current to be carried by it—and its method of trip—should also be taken into account. Talk to an electrician who will provide you with more details and assist in selecting the most suitable moulded case breaker for your system as well.
