The DOEP DFS4 016-4/0.30-B NK residual current circuit breaker is a highly advanced safety device designed to protect people, animals, and electrical installations. This four-pole residual current circuit breaker (RCCB) provides reliable disconnection of the power supply in the event of dangerously high fault currents. With a rated current of 16 A and a rated residual current of 300 mA, it is suitable for use in single-phase and three-phase networks. The compact design of the device occupies only four modular units and allows for easy installation on a DIN rail. The switch is sensitive to all currents and can detect fault currents with frequencies ranging from 0 Hz to 150 kHz, making it particularly suitable for fire-risk workplaces. The independent tripping from the mains voltage for type A fault currents and the voltage-dependent detection of smooth DC fault currents enhance the safety and reliability of the device. Additionally, the triggered position of the multifunctional switch knob facilitates troubleshooting, while the free labeling software supports easy labeling.
