What it is

The Lewden RCBO-40/30/SPA is a residual current breaker with overcurrent protection that combines 40A overload and short-circuit protection with 30mA earth leakage protection in one single module device. It is a Type A device with a B curve trip characteristic and a 6kA breaking capacity. It is used in consumer units and distribution boards to protect a single final circuit.

Before you order

  • Confirm the consumer unit accepts single module RCBOs and that the device suits the existing busbar and terminal arrangement.
  • Check that the circuit design current and cable rating are suitable for a 40A device.
  • Verify that Type A residual current protection suits the load characteristics of the circuit.
  • Confirm the 6kA breaking capacity meets the prospective fault current at the point of installation.
