Electrical protection is an essential cog of any infrastructure nowadays, be it residential, commercial, or even industrial. To ensure smooth and effective power management, an uninterrupted, smooth, safe, and reliable power supply is needed. This is where the role of electrical protection devices comes into play.
Moulded Case Circuit Breaker
MCCB is a short form for Moulded Case Circuit Breaker. It is another form of electrical protection device, which is employed when the load current exceeds the limit of a miniature circuit breaker. The MCCB offers safety against overload, short circuit faults and is also employed for switching the circuits. It can be used for higher current ratings as well as fault level even in domestic applications. The wide current ratings and high breaking capacity in MCCB mean they are extremely useful even in industrial applications.
Miniature Circuit Breaker
Miniature Circuit Breaker is one of the most prominent devices used in distribution management systems to protect electrical appliances from damages. Using an MCB is electrically safe and reliable when compared to other devices like a fuse. When referring to an MCB, swift restoration of electrical supply is possible as the switch can be reset, as opposed to a fuse, which can be used only once and eventually needs replacement.
Residual Current Circuit Breaker
A Residual Current Circuit Breaker (RCCB) is one of the protective measures that can be used for safety at home. It is an essential safety measure when it comes to the protection of power distribution to different devices/appliances. It can be elaborated on as a current sensing device, which can automatically estimate and disconnect the circuit whenever a fault occurs in the connected circuit or the current exceeds the rated sensitivity.
Air Circuit Breaker
This type of circuit breaker, which functions in the air at atmospheric pressure, is known as an Air Circuit Breaker. Over the past few years, these breakers have completely replaced oil circuit breakers. Their process of arc quenching control is in fact quite distinct in comparison to the functioning of oil circuit-breakers. In most cases, they are commonly used for low-voltage interruption.
