Schalk Central Pulse Switch ISK 41: further details
In electrical installations with multiple sub-distributions and residual current circuit breakers, an economical central ON-OFF control can be established using the specially designed switching devices ISK 41 and ISK 42. The central control inputs are galvanically isolated from the supply side inputs and outputs by optocouplers. This allows ISK 41 and ISK 42 to be connected without decoupling relays between different networks, RCDs, or potentials, unlike conventional pulse switches with central control.
