The Eaton-Moeller PFL6-40A/1N/C/003 differential circuit breaker is a modern device that combines the functions of a circuit breaker and a residual-current device (RCD). This differential circuit breaker provides reliable protection for electrical circuits against overloads, short circuits, and prevents electric shock from leakages. The operating voltage of this device is 230 V. The operating frequency is 50 Hz. The Eaton-Moeller PFL6-40A/1N/C/003 differential circuit breaker can operate at a current of 40 A. The device's leakage current is 0.03 A. There are 2 poles in this differential circuit breaker. The nominal breaking capacity reaches 4.5 kA. The device's sensitivity is set for both alternating and pulsating direct current.
