NDM5E

The NDM5E Series Electronic Molded Case Circuit Breaker (hereinafter referred to as the circuit breaker) is designed for AC 50/60Hz applications, with a rated operational voltage up to AC690V and a rated operational current up to 1600A. It is suitable for infrequent switching operations in circuits and offers functions including long-time delay, short-time delay, instantaneous, ground fault (except for NDM5E-125 and NDM5E-160 frames), pre-alarm, and undervoltage protection (with undervoltage release). It protects lines and power equipment from damage and provides feedback on current, voltage, power, energy, frequency, lifespan, open/close status, and operation count to a host computer or other energy management systems. This enables circuit breaker monitoring and control, reduces grid operation and maintenance costs, and supplies essential data for future energy efficiency systems.
