NKM1LE-63H 4 Pole 32a 40a 30ma RCBO Residual Current Circuit Breaker For Industrial Electrical

The NKM1LE-63H residual current circuit breaker has the characteristics of reasonable structure, reliable performance, beautiful and compact appearance. There are five models in total: 1P+N, 2P, 3P, 3P+N, and 4P.The shell and other components are made of impact resistant and high flame retardant materials, suitable for AC 50Hz (or 60Hz), rated voltage 400V, and single-phase 230V, rated current from 3A to 63A lines. It has protection functions such as leakage and electric shock, overload, and short circuit, and can also be added with overvoltage protection function according to user requirements, To ensure personal safety and prevent accidents caused by equipment leakage current, and can be used to protect the overload and short circuit of the line. Under normal circumstances, it is used for infrequent breaking and switching of the line. The leakage circuit breaker with a rated residual operating current of 30mA can provide direct protection against personal electric shock. If it detects abnormal currents such as residual current or overcurrent, it will quickly disconnect the circuit to prevent electrical shock accidents, circuit overload, or short circuits that could lead to electrical safety issues.NKM1LE-63H is commonly used in residential, commercial buildings, and industrial facilities to provide comprehensive circuit protection.
