Product details

Function and Usage

NB2LE residual current circuit breakers are suitable for AC 50/60Hz, rated voltage 230V/240V, and rated current up to 40A circuits, providing residual current protection, overload and short-circuit protection. When a person gets an electric shock or the circuit leakage current exceeds the specified value, the residual current circuit breaker can automatically cut off the faulty power supply within a very short time, ensuring the safety of people and electrical equipment. The residual current circuit breaker can also be used as infrequent switching in normal conditions, and is applicable to various occasions such as industry, commerce, high-rise buildings, and residential houses. The product complies with GB/T 16917.1 and IEC 61009-1 standards.
