The Doepke FIS switch DFS 4 02540,03A R is a highly advanced residual current circuit breaker designed for use in electrical installations. This switch provides reliable protection against electrical fault currents and contributes to the safety of both people and equipment. With its independent network voltage design, it is sensitive to both alternating and pulsating direct fault currents. The switch is touch-safe and features a viewing window for labeling, which facilitates identification and documentation. The switching position indicator shows the neutral position in case of a fault, allowing for quick diagnosis. The DFS 4 is robustly constructed, frost-resistant down to -25°C, and offers a short-circuit breaking capacity of 10kA. The double terminal on both sides allows for easy and flexible installation with cables up to 50mm².
