Key Features – Built for Electricians, Trusted by Installers

CE Certified to EU/UK Standards

The unit has passed independent type-testing to BS EN 61439-3, BS EN 60947-3, and BS EN 60898-1. Its construction is aligned with the demands of BS 7671 wiring regulations.

Heavy-Duty Steel Enclosure

Roll-formed from cold-rolled carbon steel and sealed beneath a matte RAL9003 polyester skin. The IK05 rating ensures the shell survives knocks, scrapes, and site traffic without deforming.

Flexible Cable Entry

Pre-punched ports ring the entire enclosure-roof, floor, left flank, right flank, and back wall:

• Roof & Floor: 20 mm, 25 mm, 32 mm

• Flanks: 32 mm plus 40 mm elongated apertures

• Back wall: Generous trunking and conduit slots

Installers can introduce cables from any compass point without field modification.

Spacious Interior Design

The 35 mm DIN rail is cantilevered above the base plate, opening a deep cavity beneath for generous conductor loops. RCBOs seat cleanly without pinching adjacent terminations.

Secure Magnetic Lid Closure

A high-pull magnet locks the hinged steel drop-flap against vibration and casual contact, yet releases with fingertip pressure for rapid breaker access.

Modular Wiring Configurations

The 14-way platform accepts these protection philosophies: • Main Switch topology - MCBs overseen by a single isolator

• Dual RCD topology - twin 30 mA zones for economical compliance

• High Integrity topology - RCDs married to selective RCBOs

• RCD-only topology - sub-panel duty with no main isolator

Match the topology to the contract brief and safety tier.

Pre-Installed Ground & Neutral Bars

Solid-copper distribution rails are factory-mounted inside, carrying multiple clamp terminals for immediate, code-compliant PE and N splitting once the lid is lifted.

Clear Circuit Labeling Area

A repositionable label sheet is taped to the inside face of the cover, letting every way be annotated for swift tracing during future service calls.

Key Applications

Multi-let houses and apartment blocks where separate circuits are needed per dwelling or floor

Workshop and light industrial units powering machine tools, compressors, and heating circuits

Social housing refurbishments requiring a higher way-count than standard domestic boards

Commercial kitchens with dedicated circuits for appliances, extraction, and lighting

Sub-distribution off a main incoming panel in larger properties

Fast FAQ – Answers for Pros & DIYers

Q1: Is the UTMCU14 suitable for a small factory, or is it only for domestic use?

A: It is rated for both residential and light commercial duty. Small factories, workshops, and retail units can use it provided the total demand does not exceed the incoming device rating.

Q2: How many spare ways should I leave for future expansion?

A: Best practice is to reserve at least two ways. With 14 positions, that leaves twelve for immediate circuits plus room for later additions such as EV charging or garden supplies.

Q3: Can I fit a surge protection device inside this enclosure?

A: Yes, provided the SPD is a DIN-rail module and the total installed depth does not exceed the 108 mm internal clearance. Mount it on the rail alongside the breakers.

Q4: Does the steel chassis need earthing separately, or is it already bonded internally?

A: The chassis is internally bonded to the earth bar. Simply connect your main earthing conductor to the provided terminal and the entire enclosure will be safely earthed.
