SONTUOEC Brand B Type Rccb Residual Current Circuit Breaker Electro-magnetic using charging station for electric vehicle
General:
STID-B RCCB B model is worked on type A and in addition for smooth DC residual currents, residual DC currents that may results from rectifying circuits and high frequency AC residual currents.It protects in the event of contunuous fault current on three phase networks. It usually is used in the field of Recharging Station, Medical Apparatus and Instruments, Controllers and Variable Speed Drives, Batter Charges and Inverters(DC)...STID-B complys with IEC/EN61008 and IEC/EN62423 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. |
