Function and use
CHINT Xinrui NM5 series plastic case circuit breakers are suitable for AC 50/60Hz, rated voltage AC1140V and below, and rated current 10A to 1600A circuits. As a device for making, breaking and carrying rated current, it can reliably protect lines and electrical equipment when they are overloaded, short-circuited or under-voltage. It can also be used as an infrequent starting and overload, short-circuit and under-voltage protection for motors. The product has the characteristics of safety, reliability, flexibility and ease of use, and intelligent IoT, and can be widely used in power distribution application scenarios in various industries such as construction, new energy, electric power, and infrastructure.
