The WMCURC6/4 four usable way consumer unit combines a 63A, 30mA RCD and four MCBs of your choice in a steel enclosure with a drop-down lid. Choose the breaker mix for your circuit schedule and order the board and protective devices together.

It is a practical option for a garage, workshop or small outbuilding installation where the design calls for four MCB-protected circuits behind a shared RCD. The IP40 enclosure needs a suitable indoor position; a garage application does not make the board weatherproof.

Four outgoing circuits, with the breakers you need

  • Four usable ways: four outgoing circuit positions in addition to the fitted RCD.
  • Four selectable MCBs included: specify the ratings and trip curves your electrician needs, instead of relying on the example mix in the photograph.
  • Shared RCD protection: the RCD provides residual current protection for the circuit group; the MCBs provide overcurrent protection.
  • Steel enclosure and metal lid: the enclosure and devices arrive as one board configuration, reducing separate component sourcing.

Plan for the shared RCD arrangement: an RCD trip can disconnect every circuit it supplies. If keeping other circuits running is important, ask about an individually protected RCBO configuration.

Product Supplied configuration Choose when
WMCURC6/4 — this product RCD + four MCBs; four usable outgoing ways You need a four-circuit board with shared residual current protection.
WMCU6/4 Main switch + four MCBs; four usable outgoing ways Your design specifies a main-switch board, with any required residual current protection provided separately.
WMCURC8/6 63A RCD + six MCBs; six usable outgoing ways You need two more outgoing circuits in an RCD-equipped board.

Specify your four MCBs

contact Power & Data UK quoting WMCURC6/4 with the required rating and trip curve for each circuit, board quantity and delivery date. We can confirm your breaker mix and build lead time before you order. Include any enclosure-size limits or requirement for surge protection.

Confirm the RCD type for the supplied build. The gallery shows a 63A, 30mA device, but the photograph alone should not be used to specify a Type A RCD. Agree the required residual current protection with your electrician when confirming the order.
