What Are The Functions Of Mcb?

Addressing the first things first –what is a miniature circuit breaker? It is an automatically operated electrical switch. Miniature circuit breakers are used to prevent damage to an electrical circuit resulting from an excess flow of current. They are designed in such a way that they trip during an overload or short circuit. This is how they protect against unforeseen electrical faults and equipment failure.

MCBs are used widely as isolating components in residential, commercial, and industrial settings. They are a part of a broader family of even more powerful circuit-breaking components.

In simple words, the primary use of a miniature circuit-breaker is to protect an installation or appliance from getting damaged against sustained overloading and short-circuit faults. However, it will also protect against earth faults. 

MCB or electrical fuses? Which one to choose?

MCBs serve a similar function to electrical fuses, which are designed to melt in case of flow of excess current. Thus, by melting, electrical fuses break a circuit in case the current flowing through them is more than a pre-designated limit. Yet, fuses can be a little less reliable than MCBs. MCBs work better even in lower voltage settings without any requirement for replacement after use.

So, unlike electrical fuses, MCB is designed to protect against both overloading and short-circuiting. These are detected using different processes. The bimetallic strip provides overload protection by using thermal operation, while short-circuit protection is ensured by the tripping coil using electromagnetic operation. 

What are the functions of the circuit breaker?

The basic function of MCB is to detect faults and glitches by interrupting the current flow so that to immediately stop the electrical flow.

The breaker monitors the circuit and in the case of a complication such as an overload, the breaker immediately shuts off that circuit. Thus large-scale damage is thus prevented.

Amazing Facts About MCB

Everyone is aware of the fact that a potentially high current load damages electric equipment or can cause severe hazards like fire! A fuse or MCB is necessary to protect these electronic products against overload. For instance, if an electrical system is overloaded, a fuse or MCB interrupts the electrical flow by cutting the circuit.

A miniature circuit breaker is often known as (MCB) is an electronic switch that halters the electrical circuit off automatically when the electrical circuit is in an unusual condition.

Nowadays, instead of using a fuse, we use the MCB in a low voltage grid. The fuse cannot feel that but it can be done more reliably by the miniature circuit breaker. MCB is considerably more sensitive than a fuse to overcurrent.

You need to take a couple of things into account before you make a note on MCB:

  • The MCB is more sensitive and can detect malfunctions in the current flow, turn switches off automatically and disconnect the connection from the power supply.
  • MCB can quickly identify the defective areas of the electrical circuit. In the fuse, the wire should be checked, on the other make, to confirm the defective area, by opening the fuse grip.
  • In addition, resuming the supply is very easy with MCB. You just have to tighten the knob. However, the whole wire must be replaced for the fuse.
  • MCB is reusable; therefore, maintenance and substitution costs are lower.
  • For MCBs the maximum rating current is 125A for separate magnetic sensitivities.
  • C32, and a specific equipment requirement is indicated by a 32A circuit breaker with a C-type sensitivity.
  • The minimum convention time depends on the circuit breaker’s mechanical engineering, which always takes some minimum time.
  • With the electricity heating action, the bi-metal band curves and breaks the connection of the circuit. A solenoid designed to respond to bigger currents complements the entire method.

MCB is better than fuse always. It provides low maintenance costs, and without professional knowledge and skills, one can easily manage and manage the switch.
