CBRs Type B
Type B residual current
Regulation 531.3.3 Tripping on:
- 50Hz sinusoidal AC
- Pulsating DC
- Smooth DC
- Residual currents ≠ 50 Hz
BSK version suitable for applications where lower sensitivity to high frequency leakage currents is required.
         BNK version (300 mA setting) meets the requirements of Regulation 531.3.2
