SONTUOEC Brand Recharge station protection switch B type RCCB Residual current circuit breaker RCD
B type leakage circuit breaker is added on the basis of AC type: pulse DC leakage, high frequency leakage (including 150HZ, 400HZ, 700HZ, 1000HZ), three-phase rectifier leakage, two-phase rectifier leakage, composite wave leakage, smooth DC leakage (pure DC DC type)Added leakage protection functions, mainly using in photovoltaic, new energ vehicles, high precision and requirements of the control system , recharge station switch ,complys with IEC62423 standards.
Tripping Current Range
| Lagging Angle | I n>0.01A | I n≤0.01A |
| 0° | 0.35I n≤I≤1.4I n | 0.35I n≤I ≤2I n |
| 90° | 0.25I n≤I≤1.4I n | 0.25I n≤I ≤2I n |
| 135° | 0.11I n≤I≤1.4I n | 0.11I n≤I ≤2In |
| Detectable wave form | Pulsating direct current sensitive | Surge current proof |
| B class 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. |
They react to AC and pulsating DC fault current which reach 0 or almost 0 within one time period of the mains frequency. |
RCCB's surge capacity. Not tripping at standardized 8/20 υs surge-current waves acc.to VDE 0432 Part 2 with surge current values of up to 250A. |
