Product details

Function and Usage

The NB1L residual current device is suitable for AC 50Hz, rated voltage 230V, and rated current up to 25A circuits. When a person is electrocuted or the grid leakage current exceeds the specified value, the residual current device can quickly cut off the faulty power supply within an extremely short time, protecting personal safety and electrical equipment. It also provides overload and short-circuit protection for the circuit and can be used for infrequent switching of the circuit. This product is applicable in various places such as industrial, commercial, high-rise buildings, and residential areas. It complies with the standards GB/T 16917.1 and IEC 61009-1, and has obtained CCC, CE, VDE, and SEMKO certifications.
