Application
JC3RH-BS Type B RCCBs are suitable for non-linear circuits that are able to generate leakages with high direct current (higher than 6 mA) and/or high frequency components, for example single-phase or poly-phase rectifiers, rectifiers with active correction of the power factor, continuous voltage generator with no separation from AC networks and inverters at variable frequency.
B Type
Tripping is ensured for sinusoidal AC residual currents pulsed DC residual currents, alternating residual sinusoidal currents up to 1000Hz, pulsating direct residual currents and for smooth direct residual currents, whether applied suddenly or increasing slowly.
