The Hager CFB640E four-pole residual current circuit breaker is designed for commercial, industrial and photovoltaic installations with TT, TN-S and TN-C systems. It protects against AC residual currents with pulsating DC and smooth DC components, and withstands high-frequency current surges up to 1 kHz. It is suitable for power equipment without galvanic isolation from the mains.
It is used in electric vehicle charging stations, photovoltaic installations, frequency and speed converters, lifts and UPS systems. It has an integrated label holder, accepts MZxxx auxiliary contacts and is compatible with MZ906 and MZ916 remote-control motors.
