JC3RS-B Residual Current Device
Features
Electromagnetic Type
Earth Leakage Protection
Breaking capacity 6KA,10KA
Rated current up to 100A
Detect smooth DC residual currents
Tripping sensitivity: 30mA

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.
Application
JC3RS-B Type B RCCBs are suitable for non-linear circuits that are able to generate leakage with high direct current（higher than 6mA）and/or high frequency components, for example single-phase rectifiers, rectifiers with active correction of the power factor, continuous voltage generator with no separation from AC networks and inverted at variable frequency.
