Product details
Basic parameters：
The CH24L series leakage circuit breakers have the characteristics of advanced structure, reliable performance, high breaking capacity, and beautiful and compact appearance. housing and main components are made of impact-resistant and high-flame-retardant materials. It is suitable for alternating current of 50Hz or 60, rated working voltage of 400V and below, and rated current of 6A to 63A. It is mainly used for the lighting distribution line and of office buildings, residential buildings and similar buildings for overload, short circuit and leakage protection. It can also be used for infrequent switching of lines under normal conditions.
The product the standard GB16917.1.
Model meaning:
