Residual current circuit breaker ELKO
RCB-2:Residual current device 2-pole
* Residual current devices RCB-2 are used as protection of energized parts in a circuit against indirect touching. It is a protection against direct touching, against residual voltage on grounded parts which apear when there is a fault in eletrical installation and for prostection against direct contact with energized parts in case IΔN ≥ 30 mA.
* RCDs can be used in the main systems TN-S, TN-C, TT or in other words - in all systems where there is separated neutral and protective wire (VDE 0100 part 410).
* Residual current device RCB-2:
* Type A - sensitive to alternating and pulsating direct current
* Type AC - sensitive to alternatingt and residual current
