The NM10 series plastic-enclosed circuit breaker is mainly used for non-frequent operation of AC 50Hz, rated working voltage up to 380V, rated current up to 600A of distribution network. It is used to distribute electricity and protect lines and power equipment from over-loading, short circuit, under-voltage and other faults. The transparent cover of the series derivative circuit breaker is made of new, high-temperature and high-strength polycarbonate material, which can visually judge the on-off state of the contacts and is widely used in construction sites for temporary power supply.
The NM10 series molded case breakers are designed for infrequent operation in 50 Hz AC distribution networks with a rated voltage up to 380 V and a rated current up to 600 A. They protect circuits from overload, short‑circuit, and undervoltage faults and are widely used in temporary construction site power supplies.\n\nThe manual details environmental limits, technical parameters, accessory options, mounting dimensions, and ordering procedures. It also explains the operation of thermal‑magnetic and instantaneous trip units, as well as the transparent polycarbonate cover that allows visual inspection of the contacts. This manual is written in Chinese.
