The GmbH residual current circuit breaker DFS4 063-4/0.30-B SK from Doepke is a highly advanced residual current device designed for use in single-phase and three-phase networks. This switch provides reliable protection against dangerous residual currents that can pose risks to people, animals, and electrical installations. With a rated residual current of 0.3 A and a rated current of 63 A, the DFS4 is suitable for a wide range of applications. The compact design of the device occupies only four modular units and allows for easy installation on a DIN rail. The switch is all-current sensitive and can detect residual currents with frequencies ranging from 0 Hz to 150 kHz, making it particularly versatile. Additionally, it offers high immunity to operational leakage and fault currents at frequencies starting from 1 kHz. The type B tripping characteristic ensures a targeted response to specific residual currents, while the large double-decker terminals can accommodate thicker conductor cross-sections. The integrated labeling software simplifies the labeling and documentation process.
