Type A EV
1. General
1.1 Function
Residual Current Circuit Breaker VKL11 TYPE A EV (RCCB TYPE A EV) is the Type EV RCCB which has been developed specifically for EV charging systems and can detect AC and DC residual currents in accordance with the requirements of EN61008-1 and IEC62955(RDC-PD:Residual Direct Current Protective Device )
VKL11 Type A EV RDC-PD/RCCB is designed specifically for use in Mode 3 charging applications.
1.2 Selection
Detectable wave form AC class
Tripping is ensured for slowly increasing sinusoidal AC
residual currents
A class
Tripping is ensured for sinusoidal AC residual currents and for pulsed DC residual currents, whether applied suddenly or increasing slowly.
Smooth DC 6mA
smooth DC residual currents (switch-off at max 6 mA)
1.3 Approvals and certificates :UKCA,CE
Tripping sensitivity
30mA - 50Hz sinusoidal AC; Pulsating DC
Smooth DC ≥ 6 mA (RDC-PD)
Tripping time
Instantaneous
It ensures instantaneous tripping(without time-delay).
