Introduction
Molded Case Circuit Breakers, also known as device-type circuit breakers, seal all parts within a plastic enclosure. Auxiliary contacts, under-voltage release, and auxiliary release are typically modular. Due to their compact structure, molded case circuit breakers are essentially unmaintainable. They are typically operated manually, with larger capacities available for electric operation. With the application of electronic overcurrent release mechanisms, molded case circuit breakers can be classified into A and B types. Type B offers a three-stage protection feature, but due to cost considerations, the market for type A products with thermal-magnetic release mechanisms is more prevalent. Molded case circuit breakers house contacts, arc-extinguishing chambers, release mechanisms, and operating mechanisms within a single plastic enclosure. They are generally not designed for maintenance and are suitable for protecting branch circuits. Overcurrent release mechanisms include thermal-magnetic and electronic types. Generally, thermal-magnetic molded case circuit breakers are non-selective, offering only over-current long-delay and short-time instantaneous protection. Electronic molded case circuit breakers offer four protection functions: over-current long-delay, short-time instantaneous, short-time instantaneous, and ground-fault protection. Some newly introduced electronic molded case circuit breakers also feature regional selective linking. Most molded case circuit breakers are operated manually, with some featuring motor-operated mechanisms.
