What the product is

Hager Design 10 12 way consumer unit bundle with Type 2 SPD and 9 selectable RCBOs is built around the Hager VML112SPDRK consumer unit and nine customer selected Hager ADA series RCBOs. The board is a round knockout Design 10 consumer unit with a 100A switch disconnector incomer and Type 2 SPD. The selectable outgoing protection comes from the Hager ADA family, covering ADA306G 6A, ADA310G 10A, ADA316G 16A, ADA320G 20A, ADA325G 25A and ADA332G 32A. On the website that makes the product a configurable bundle based on one fixed board and one fixed Hager RCBO family rather than a single prebuilt circuit schedule.

That is the right way to present it. Hager's official references verify the board and RCBO families, while your site bundle definition sets the included RCBO quantity at nine. The copy therefore needs to explain both sides clearly. The enclosure specification is fixed and verified. The RCBO family is fixed and verified. The outgoing rating mix is selected by the customer from the stated ADA options.

Why the 12 way bundle variant matters

The practical reason to choose this variant is capacity. VML112SPDRK sits in the middle of the three bundle sizes you asked for. It gives you more outgoing room than the smaller 8 way enclosure but avoids stepping up to the much wider 18 way board. At 368.4 mm wide it is still a single row enclosure, which makes it attractive for standard domestic installations where the circuit schedule has grown beyond the smaller board size but does not justify the largest single row format.

The nine selectable RCBO positions strengthen that middle ground role. For many refurbishments and new domestic boards, nine outgoing RCBOs cover a useful range of circuit schedules without oversizing the enclosure. That keeps the page commercially useful because the customer sees a verified Hager mid size bundle rather than a one size fits all description that could apply to every board on the site.

Board details that matter in practice

Hager identifies VML112SPDRK as a Design 10 surface mounted steel consumer unit with 12 ways, one row and one rail. The official datasheet confirms indoor use only, IP2XC ingress protection, IK05 impact resistance and a 100A rated current. Round knockouts and the Design 10 enclosure format make it a defined Hager board choice rather than a generic metal enclosure. Hager's wider Design 10 catalogue also ties these boards to BS EN 61439-3 including Annex ZB and confirms that references ending in SPD come with Type 2 SPD fitted.

The same Hager catalogue identifies VM04CE as the standard meter tail cable entry plate for Design 10 boards and lists accessories including VM02CE, VA10MT and VAP00. Hager also recommends these switch disconnector SPD boards for TT systems when RCBOs are used on all outgoing circuits. That context matters because it shows how the bundle sits within Hager's intended installation ecosystem rather than being treated as a loose collection of parts.

RCBO selection and buying logic

The bundle stays within the Hager ADA reduced height RCBO family for all selectable outgoing devices. Hager identifies the ADA306G to ADA332G range as 1P 6kA B curve 30mA Type A RCBOs for final circuits from 6A to 32A. Keeping the bundle inside one RCBO family avoids mixed specifications and gives the buyer a clear set of selectable ratings. The product page can therefore target both the board bundle intent and the underlying RCBO demand without inventing unverified compatibility with other devices.

For the buyer, the important point is that the enclosure and protection family are fixed while the rating mix is flexible. That makes the bundle easier to specify against real board schedules. A customer can choose the RCBO ratings needed for the outgoing circuits while staying within one verified Hager bundle structure.

Who this exact bundle suits

This bundle suits mid size single phase domestic boards, standard refurbishment projects, consumer unit replacements and new installations that need more headroom than a compact enclosure but still benefit from a single row board. It is also a sensible fit where the installer wants RCBO based outgoing protection with customer selected 6A to 32A options and integrated Type 2 SPD in the board from the outset.

Why buy this exact variant

Choose this 12 way Hager bundle when the job needs a Design 10 round knockout board with Type 2 SPD and nine customer selected Hager ADA RCBOs. The value in this exact version is the balance between board width and outgoing flexibility. It gives you a clearly verified Hager enclosure platform, a defined RCBO family and more circuit headroom than the 8 way bundle without moving into the widest single row option.
