Molded Case Circuit Breaker MCCB is a common circuit breaker, which is widely used in life. Electricity is closely related to us, so we really need to understand the characteristics and applications of molded case circuit breakers. Molded case circuit breakers are generally divided into air circuit breakers and leakage circuit breakers. In the following, I will specifically introduce moulded case circuit breakers to everyone. I hope everyone can take a good look.
The role of Molded Case Circuit Breaker MCCB:
1. There are three types of Molded Case Circuit Breaker MCCB, namely air circuit breakers and leakage circuit breakers, which have short circuit and overload protection functions. Second, with leakage protection. Third, with short circuit, overload, leakage protection. To see the specific thing, the short-circuit means that the electric switch will trip, the overload means that the current switch that exceeds the switch will jump, and the leakage means that the single-phase leakage of the line after the switch will jump to the rated leakage current switch of the switch to protect it. effect.
2. Molded case circuit breaker (including cm1 100 mccb) can play the role of overload, short circuit, under voltage. Under the premise of molded case circuit breaker, leakage circuit breaker can protect human body and other functions!
3. Molded case circuit breaker (including cm1 100 mccb) can automatically cut off the current after the current exceeds the trip setting. Molded shell refers to a plastic insulator used as the housing of the device to isolate the conductors and the grounded metal portion. Molded case circuit breakers usually contain a thermal-magnetic trip unit, while large-sized molded case circuit breakers (including cm1 100 mccb) are equipped with a solid-state trip sensor. The trip unit is divided into: thermal magnetic trip and electronic release. The dynamic and static contacts and contact bars of the circuit breaker are designed to be parallel. The electric repulsive force generated by the short circuit is used to break the moving and static contacts, and the breaking capacity is high, and the current limiting characteristics are strong.
Through the introduction of molded case circuit breakers above, I think we must understand a lot. Everyone knows more about this kind of related knowledge that can be applied to our lives. For example, buying a circuit breaker and the like. If you want to buy a circuit, then I strongly recommend that you buy this molded case circuit breaker. In fact, when everyone is OK, they can look at the knowledge about circuit devices. Knowing more about them will not be a bad thing.
