Moulded Case Circuit Breaker – What You Need to Know
A Moulded Case Circuit Breaker (MCCB) is a type of electrical switch that protects electrical equipment from damage due to excessive current flow. It is used to break or disconnect an electrical circuit in the event of short-circuit or overload. MCCBs are commonly used in various industrial and commercial applications because they are reliable and robust.
China Foretech Elec.App. (Jiangsu)co., LTD is a leading supplier of MCCBs, Circuit Breakers, Miniature Circuit Breakers, Air Circuit Breakers, Load-Disconnector Switches, and Surge Protective Devices. They are dedicated to providing high-quality products at competitive prices.
MCCBs can be divided into two categories – thermal and magnetic. The thermal component of an MCCB measures the heat generated by the current flow and breaks the circuit if it exceeds a certain threshold. The magnetic component of an MCCB detects a sudden surge in current and breaks the circuit if it goes beyond a predetermined limit.
MCCBs come in various amperage ratings, and the appropriate size and type should be selected based on the equipment's power requirements. The MCCB's tripping time should be faster than the equipment's minimum short-circuit current rating to protect it from damage.
Installing MCCBs requires proper knowledge and expertise. It is crucial to follow the manufacturer's guidelines and local electrical codes to ensure safe and efficient installation. Regular maintenance of MCCBs is also essential to ensure their proper functioning and prevent potential hazards.
In summary, an MCCB is an essential component of an electrical circuit that protects equipment from damage due to excess current flow. China Foretech Elec.App. (Jiangsu)co., LTD is a reliable supplier of MCCBs and other related products.
