Product overview

NM10 series plastic shell circuit breakers (hereinafter referred to as circuit breakers) are mainly applicable to infrequently operated circuits of distribution networks with AC 50Hz, rated working voltage up to 380V and rated current up to 600A. They are used to distribute electric energy and protect lines and power supply equipment from overload, short circuit, undervoltage and other faults. The circuit breaker of 250A and below can also be used as infrequent starting, overload, short circuit and undervoltage protection of motor.

The cover of the transparent shell circuit breaker derived from this series is made of high temperature resistant and high-strength polycarbonate material, which can visually judge the on-off state of the contact, and is widely used in temporary electric field on construction sites.

Standards: GB 14048.2, IEC 60947-2.
