With a remote drive (ARD), connected residual current circuit breakers are switched on and off remotely. This significantly increases system availability. ARD with automatic function automatically switches the circuit breaker back on. If a system error is detected, it will not be switched back on. The Doepke residual current circuit breakers DFS 2 and DFS 4 can be monitored and switched using the devices from the DFA 3 series, which are only one TE wide. Depending on the variant, the DFA switches the RCCB back on three or zero times. The DFA 3 signals the status of the connected residual current circuit breaker via a semiconductor output. Properties: - retrofittable remote drive for Doepke residual current circuit breakers of the DFS 2 and DFS 4 series, - very compact design, width 1 TE, - versions available with and without three switch-on attempts Mounting type: - to the left of the residual current circuit breaker by clamping - quick fastening to the mounting rail - installation position as desired Areas of use: Remote drives are used wherever electrical installations are difficult to access or where a high level of system availability is required. These can be, for example, agricultural operations, small wind turbines, photovoltaic installations, charging stations for electric vehicles, pumping stations, sewage treatment plants and telecommunications systems. Notes: According to the standard, automatic restarting is only permitted in areas to which only electrically trained persons and qualified electricians have access. The remote drive does not affect the function of the residual current circuit breaker.
