What it is

The Lewden RCBO-20/30/SPA is a 20A residual current breaker with overcurrent protection (RCBO) for use in consumer units and distribution boards. It combines a 30mA Type A residual current device with a B curve miniature circuit breaker in a single 1 module device. It provides protection against earth leakage, overload and short circuit on final circuits.

Before you order

  • Confirm the existing device is 20A, 30mA, B curve, Type A, 6kA and 1 module wide.
  • Check the consumer unit or distribution board accepts 1 module RCBOs.
  • Verify the part number RCBO-20/30/SPA matches the required replacement.
  • Ensure the circuit's protective conductor and wiring are suitable for a Type A RCD.
