Technical Field

[0001] The utility model belongs to the technical field related to circuit breaker life testing, and particularly relates to a closing and opening component for life testing of a molded case circuit breaker. Background Art

[0002] A molded case circuit breaker (MCCB) is a device used to protect circuits and their components from overcurrent. It automatically interrupts current flow when the current exceeds the trip setting, preventing damage from overloads or short circuits. The MCCB's housing is typically made of plastic insulation, which isolates the conductors from each other and from grounded metal parts. This type of circuit breaker typically includes a thermal-magnetic trip unit, and larger models may also be equipped with a solid-state trip sensor. Trip units are available in two types: thermal-magnetic and electronic.

[0003] The closing and opening components of the molded case circuit breaker life test are devices used to detect the service life of the molded case circuit breaker.
