A circuit breaker is an electrical switch that automatically opens and closes a circuit to interrupt current flow when it senses an overload or short-circuit. There are many different types of circuit breakers, but two of the most common are the MCB (molded case breaker) and MCCB (molded case current limiting breaker). So what’s the difference between these two types of breakers? Let’s take a closer look.
What is MCB?
MCB is a term that stands for Micro Circuit Breaker. MCBs are small circuit breakers that are used to protect electrical circuits from overloads and short circuits. MCBs are typically used in household and office applications, but can also be used in industrial settings. MCBs are available in a variety of sizes and ratings, and can be configured to trip at different currents. MCBs are typically mounted on DIN rails, and can be clipped onto electrical wiring. MCBs are typically used to protect against overcurrents, but can also be used to provide protection against voltage spikes, line faults, and phase loss. MCBs can be used as standalone devices or as part of an electrical panel. When selecting an MCB, it is important to consider the amperage rating, voltage rating, and mounting type. MCBs are an essential part of any electrical system, and can help to prevent damage to equipment and property.
What is MCCB?
MCCB stands for molded case circuit breaker. MCCBs are designed to protect electrical circuits from overloads and short circuits. MCCBs are available in a variety of sizes and ratings, and they can be used in both residential and commercial applications. MCCBs are typically installed in electrical panels, and they can be used to protect both indoor and outdoor circuits. MCCBs are available in both single-pole and three-pole configurations, and they can be ordered with either thermal or magnetic protection. MCCBs can also be equipped with a variety of auxiliary features, such as ground fault protection, overcurrent protection, and shunt trips. MCCBs are an essential part of any electrical system, and they play a critical role in protecting both people and property.
Difference between MCB and MCCB
MCB and MCCB are two types of electrical circuit breakers. MCBs are used for low voltage applications, while MCCBs are used for high voltage applications. MCBs are also cheaper and smaller than MCCBs. MCBs can handle lower currents than MCCBs, but MCCBs can handle higher voltages. MCBs are also faster at interrupting electrical current than MCCBs. MCBs are typically used in domestic applications, while MCCBs are used in industrial and commercial applications.
Conclusion
The main difference between an MCB and an MCCB is that the MCCB has a higher interrupting rating. This means that it can handle more current peaks without tripping. If you are looking for a breaker that can handle more load, then you should consider purchasing an MCCB.
