Product Details

B type residual current circuit breakers

B type residual current circuit breaker (earth leakage protection)

The B type residual current circuit breakers provide:
Protection in the event of a continuous fault current on three-phase networks generated by:
- Controllers and variable speed drives
- Battery chargers and inverters
- Backed-up power supplies

They include and also guarantee protection against fault currents:
- Sinusoidal AC residual currents (AC type)

- Pulsed DC residual currents (A type)


Applications requiring 'B' types include:    

         
EV & PV installations
Frequency converters
UPS installations
High-frequency power converters
Building site power supply cabinets
