Technical Field
The invention relates to the technical field of molded case circuit breakers, in particular to a molded case circuit breaker with a heat insulation shell.
Background
The molded case circuit breaker is also called a device type circuit breaker, all parts are sealed in a plastic shell, and an auxiliary contact, an undervoltage release, a shunt release and the like are modularized. The molded case circuit breaker can automatically cut off the current after the current exceeds the trip setting. Because the structure is very compact, the molded case circuit breaker can not be overhauled basically, manual operation is mostly adopted, and high-capacity electric opening and closing can be selected.
In order to avoid the circuit breakers generating heat in the working process, the temperature of the working environment is increased, and the normal work is influenced, each circuit breaker needs to be insulated independently, but the heat generated by the circuit breaker is not enough to be separated, and the external heat needs to be separated together, so that the heat insulation effect can be really played.
