Auxiliary device for distribution board devices Doepke

A remote actuator (ARD) is used to remotely switch connected circuit-breakers on and off. This significantly increases system availability. ARDs with an automatic function automatically switch the circuit-breaker back on. No reclosing occurs if a system error is detected. Devices from the DFA 3 series are extremely compact remote actuators for the DFS 2 and DFS 4 residual current circuit-breakers across the entire rated current range. They are available in the versions without and with three restart attempts. If the latter version recognises all attempts as unsuccessful, it blocks any further switching operations. All designs have the option of a manual switch-off and a semiconductor output, which signals the status of the flange-mounted RCCB. Properties: retro-fittable remote actuator for Doepke residual current circuit-breakers of series DFS 2 and DFS 4; extremely compact design, installation width of 1 MW; designs without and with three activation attempts available; Mounting: mounting by clamping to the left of the residual current circuit-breaker; quick fastening to mounting rail; any installation position; Application areas: Remote actuators can be used anywhere where electrical installation are difficult to access or where high system availability should be achieved, This might be on agricultural premises, in small wind power stations, photovoltaic installations, charging stations for electric vehicles, pump stations, sewage treatment plants and telecommunications systems. Hints: According to the standard. automatic restart is only permitted in areas where only trained electricians have access. The remote actuator does not affect the function of the residual current circuit-breaker.
