What it is

The Lewden RCBO10-40/30/1M/C is a residual current breaker with overcurrent protection (RCBO). It is manufactured by Lewden and rated at 40A with a Type C curve, 30mA residual operating current and 10kA breaking capacity. The device is single-pole (Sp) and occupies a 1M module width.

Before you order

  • Confirm the 40A current rating and Type C curve are correct for the circuit's load and fault characteristics.
  • Check the 30mA residual operating current meets the required protection level for the installation.
  • Verify that the single-pole, 1M module format is compatible with the available ways in the distribution board.
