ABB F200 RCCB, 63A, 2 Pole, 30mA, 230V ac

this means that they detect sinusoidal AC currents as well as pulsating DC currents. In addition to this, they are also tested according to IEC/EN 62423 which foresees the application of a simulated multi-frequency residual current with appropriate coefficient associated to the each level of frequency up to 1kHz.

The intervention characteristic has a short-time delayed which prevents unwanted tripping in case pulsed leakage currents of up to ten milliseconds occur at activation of filters.
The RCDs Type F have a surge current withstand capacity of more than 3kA and can accept superimposed smooth DC residual currents of up to 10mA without affecting their standard functionality.
