SONTUOEC RCD Type B 4P 10KA 415V Residual Current Circuit Breaker RCCB
Type B RCCBs, in addition to normal AC, can detect high frequency AC and pure DC earth leakage currents. Reducing the risk of fire and/or electrocution through automatic disconnection of the electrical supply relies on the selection of the correct type of RCCB.
View 'B' Type
Applications requiring 'B' types include:
EV & PV installations
Frequency converters
UPS installations
High-frequency power converters
Building site power supply cabinets
Technical Data
1. Provides protection against earth fault/leakage current and function of isolation.
2. High short-circuit current withstand capacity.
3. Applicable to terminal and pin/fork type busbar connection.
4. Equipped with finger protected connection terminals.
5. Automatically disconnect the circuit when earth fault/leakage current occurs and exceeds the rated sensitivity.
6. Independent of power supply and line voltage, and free from external interference, voltage fluctuation.

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. |
Approvals: CE,CB, SAA, ISO9001
