Why Choose the ABB UK648NB UK600 Flush-Mounted Consumer Unit?
The ABB UK648NB, manufacturer order code 2CPX031377R9999, is a four-row, 48-module flush-mounted consumer unit without a door or trim frame from the ABB UK600 enclosure range. Designed for low-voltage electrical distribution, this enclosure provides a practical solution for organising modular protective and switching devices in residential, commercial and building services installations.
Featuring an IP30 protection classification, RAL 9016 traffic white finish and Class II double-insulated construction, the ABB UK648NB combines a professional appearance with practical electrical installation features. Its four-row configuration provides 48 modular positions, arranged across four rows of 12 modules, making it suitable for distribution boards requiring multiple circuits and organised device grouping.
The UK648NB is manufactured with a thermoplastic enclosure housing and incorporates a removable device carrier, integrated cable-retaining rail and N/PE quick-connect terminals. Preformed cable-entry positions support flexible wiring routes, while the flush-mounted design allows the distribution board to be recessed neatly into a suitable wall.
With overall enclosure dimensions of 722 mm high × 362 mm wide × 97 mm deep, the ABB UK648NB is designed for compatible UK600 installations where a separate front trim frame and door can be selected as required. Its coordinated construction supports efficient assembly, accessible wiring and dependable operation within the specified electrical ratings.

Reliable Electrical Distribution with a Four-Row Flush-Mounted Design
The ABB UK648NB provides a structured enclosure arrangement for installations requiring up to 48 standard modular positions. Its four-row layout supports logical grouping of circuit breakers, residual current devices and other compatible modular equipment, helping electrical installers create distribution boards that are straightforward to identify, inspect and maintain.
The flush-mounted construction allows the enclosure to be recessed into a suitable wall opening. ABB specifies both flush-mounting niche dimensions and hollow-wall cut-out dimensions, helping installers plan the installation according to the wall construction and the selected mounting method.
The Class II double-insulated thermoplastic housing provides an important insulation characteristic for the enclosure assembly. Its IP30 classification provides protection against relevant solid-object access, while the IK07 impact-resistance rating indicates a defined level of resistance to mechanical impact. The IP30 rating does not provide a rated level of protection against water ingress, so the installation environment must be selected accordingly.
Practical cable-management features are integrated into the UK648NB design. Preformed openings at the top, bottom, sides and rear support alternative cable-entry routes, while the integrated cable-retaining rail and strain-relief provisions help maintain an organised wiring arrangement. The removable device carrier further supports installation and servicing of compatible modular equipment.
The UK648NB is supplied as a basic consumer unit configuration without a decorative trim frame or door. Compatible finishing accessories must be selected separately where required. The stated electrical ratings apply to the specified enclosure design and do not replace the need to verify protective device ratings, circuit loading, thermal performance and the requirements of the complete distribution assembly.
