What it is

The Lewden B63/30/2 is a residual current device (RCD) rated at 63A with 30mA sensitivity, in a 2 pole configuration. It monitors the circuit for residual current to earth and disconnects the supply when that current exceeds the trip threshold. It forms part of the Lewden electrical range.

Before you order

  • Confirm the 63A rated current matches the circuit design.
  • Check that 30mA is the required trip sensitivity for the installation.
  • Verify that a 2 pole device suits the wiring configuration.
  • Match the part number B63/30/2 against the device being replaced.
