Residual Current Circuit Breaker 4P Type B, FI Circuit Breaker 40A 30mA 4-Pin Residual Current Circuit Breaker All-Current Intensive Switch Automatic Fuse for Wall Boxes Charging Stations

Robust design: the FI circuit breaker 40 A 30 mA 4-pin is made of high-quality ABS material, which provides excellent insulation. It works even in extreme temperatures and is both heat and cold resistant
Technical superiority: Our FI circuit breaker is characterised by a 4-pin, type B construction, with a rated current of 40 A and a residual current trigger with a sensitivity of 30 mA
Increased safety features: it protects people from dangerous body currents by detecting residual currents and disconnecting the faulty circuit. our residual current circuit breaker and interrupts the power supply when it detects residual currents over 30 mA and offers a protective shut-off capacity of up to 10 kA
Versatile application: the RCD circuit breaker 40 A 30 mA 4-pin is an indispensable electrical protection device. It is ideal for current transformers that power inverters (convert DC to AC), and is used in residual current/AC devices, such as wall boxes, charging stations, photovoltaic systems and inverter systems
All-current sensitivity (type B): Detects AC, pulsating DC, smooth DC and high-frequency residual currents up to 2 kHz
