30mA Type B Residual Current Circuit Breaker, 40A 30mA 3P+N 10kA RCCB Residual Current Circuit Breaker, AC400V, suitable for charging stations and industrial equipment GYL9

【40A/30mA Rated】: This 30mA 40A Type B residual current circuit breaker is suitable for circuits operating at 50/60 Hz AC, with a rated voltage of 400V and a rated current of 40A. Featuring a 30mA tripping current, the circuit breaker immediately cuts off the faulty power supply when the leakage current exceeds the specified value, thus protecting personnel and electrical equipment. 【Full-Frequency Leakage Protection】: This Type B residual current circuit breaker accurately detects AC leakage currents, pulsed DC leakage currents, smooth DC leakage currents, composite wave leakage currents, and high-frequency leakage currents up to 1 kHz. It covers complex electrical usage scenarios. 【Stable Performance】: Made of ABS, this 40A 30mA residual current circuit breaker (RCCB) is a type B RCCB offering excellent insulation properties and resistance to high and low temperatures. With an IP20 protection rating, it is robust and durable. 【Flexible and Convenient Installation】: Thanks to its dual-wiring design, the 40A 30mA RCCB allows for freely switching between input and output directions, regardless of whether it is a "power input" or a "load output." Compatible with standard 35mm DIN rails, it adapts to various distribution box configurations. 【Application Scenarios】: This 30mA 40A Type B residual current circuit breaker is specially designed for high-demand environments, ensuring electrical safety in photovoltaic systems, charging stations, industrial equipment, and commercial buildings.
