CHINT NM8NL-400 4P RCD1+NM8N-400S Circuit Breaker, 400A, 4P, 50kA (thermal & magnetic)

The CHINT NM8NL-125 4P RCD1 + NM8N-125S TM 100 4C residual current device is a combined solution that integrates an automatic circuit breaker and RCD in a single enclosure. It provides full protection: against overloads and short circuits (overcurrents) and against earth leakage currents. Equipped with thermal and electromagnetic trip units for reliable operation in fault conditions, as well as a sensitive residual current device (RCD1) with a leakage current setting range of 30 mA – 1 A. The four-pole design ensures protection of all phases and neutral conductor, while the high breaking capacity of 50 kA allows the device to be used in high-power industrial networks.
