Function and Usage
The NL1E-63 residual current circuit breaker (without overcurrent protection) is suitable for AC 50/60Hz, rated voltage of 230V for two-pole and 400V for four-pole, with a rated current up to 63A. When a person gets electrocuted or the leakage current of the power grid exceeds the specified value, the residual current circuit breaker can quickly cut off the faulty power supply in an extremely short time, protecting personal safety and electrical equipment. It can also be used for infrequent switching of circuits. The product is suitable for various places such as industry, commerce, high-rise buildings, and residential areas. It complies with the standards GB/T 16916.1 and IEC 61008-1, and has obtained CCC certification.
