What it is

The Lewden RCBO10-20/30/1M/C is a single-pole residual current breaker with overcurrent protection (RCBO). It combines a 20A Type C overcurrent trip with 30mA earth leakage protection in a single module. The device has a 10kA short-circuit breaking capacity.

Before you order

  • Confirm the Type C curve and 20A rating suit the circuit's expected load and inrush characteristics.
  • Check the 30mA residual current sensitivity and 10kA breaking capacity meet the installation's protection requirements.
  • Verify the single-pole configuration and 1M module width fit the consumer unit or distribution board.
  • Match the part number RCBO10-20/30/1M/C to the existing or specified device.
