MCB Vs MCCB • In this video you will get to know what are the major difference between MCB and MCCB • hope you will like this video • What is a Miniature Circuit Breaker (MCB)? • An MCB, or a miniature circuit breaker, is an automated electrical device intended to protect an electrical circuit from damage caused by excess current, usually occurring from an overload or short circuit. Its fundamental function is to interrupt the current flow once a fault is detected. Its working principle is quite simple. The MCB has two contacts, where one is movable and the other one is fixed. As the current increases from the predefined limit, the movable contacts get disconnected from the fixed contacts, consequently, the circuit gets open and disconnect them from the main supply. • What is a Moulded Case Circuit Breaker (MCCB)? • An MCCB, or a moulded case circuit breaker, is an electric device designed to protect the circuit from overloading. However, unlike the MCB, it is used in places where adjustable tripping is required. Essentially used for high current applications, the MCCB features a manually operated switch for tripping the circuit. Talking about its working principle, the MCCB has two arrangements; one for the over temperature and the other one for over current. It has a bimetallic contact, which expands and contracts with the change in temperature. During the normal operating conditions, the contact allows the current to flow through the circuit. However, if the current rises beyond the predefined limit, the contacts will get warm and expand until they get open. As a result, the circuit gets disconnected from the main supply, protecting the equipment from damage. • in this Video, I have used tense Electronic Company MCCB which model number is UEM5-250L • Specification of this Moulded Case Circuit Breaker (MCCB) • To Buy this MCCB Contact 👇👇👇 • Khodiyar engineering works • Address- shed L/46, 47,48 mm-50 G.
