Key Features – Built for Electricians, Trusted by Installers

CE Certified to EU/UK Standards

Independently type-tested to BS EN 61439-3, BS EN 60947-3, and BS EN 60898-1. The design adheres to BS 7671 wiring regulations, providing a compliant foundation for domestic electrical upgrades.

Heavy-Duty Steel Enclosure

Fabricated from cold-rolled carbon steel with a uniform RAL9003 polyester powder skin. The IK05 impact classification ensures structural resilience against mechanical stress during transport, handling, and installation in confined voids.

Flexible Cable Entry

Pre-punched ports sit on the roof, floor, left flank, right flank, and back wall:

• Roof & Floor: 20 mm, 25 mm, 32 mm

• Flanks: 32 mm plus 40 mm slots

• Back wall: Wide trunking and conduit apertures

Cables thread in from any face to suit cramped flat layouts.

Spacious Interior Design

The 35 mm DIN rail is elevated on integral stand-offs, generating a sub-rail void for unimpeded conductor bending radii. This geometry permits RCBO insertion in a 158 mm chassis without compromising adjacent termination access.

Secure Magnetic Lid Closure

A ferrite magnet secures the hinged steel fascia panel against inadvertent disengagement from vibration or incidental contact. Release force is calibrated for single-handed operation during breaker inspection or overcurrent reset procedures.

Modular Wiring Configurations

The 6-way platform accommodates four distinct protective topologies:

• Main Switch distribution

• Dual RCD zonal protection •High Integrity selective discrimination

• RCD-only sub-panel derivation.

Configuration is dictated by installation scope and economic parameters.

Pre-Installed Ground & Neutral Bars

Solid-copper busbar assemblies are factory-integrated, equipped with multiple clamping terminals for direct connection of protective earthing and neutral conductors. No supplementary terminal hardware is required for standard installation.

Clear Circuit Labeling Area

An adhesive-backed label substrate is affixed to the internal panel surface, facilitating circuit-by-circuit annotation. This documentation protocol reduces diagnostic latency during subsequent maintenance or fault-rectification activities.

Key Applications

Urban studio flats requiring consolidated lighting, power, and appliance circuit protection

Ancillary dwelling units (granny annexes) annexed to principal residences

Small-scale retail kiosks and pop-up units with limited socket and lighting requirements

Compact home office conversions in spare bedrooms or loft spaces

Residential park homes and static caravan units with reduced circuit enumeration

Fast FAQ – Answers for Pros & DIYers

Q1: Do I need to leave the plastic transit covers on the knockouts until installation?

A: Yes. The plastic discs keep dust and debris out during storage and transport. Remove them only when you are ready to insert the cable gland or conduit, then discard.

Q2: How many RCBOs can I install in this 6‑module board?

A: Each RCBO occupies 2 modules, so you can fit up to 3 RCBOs. If you need more circuits, we recommend using MCBs (1 module each) for standard circuits and reserve RCBOs for critical ones.

Q3: Is the enclosure suitable for unheated garages or outbuildings?

A: The unit has an IP20 rating, suitable for dry indoor areas. For unheated spaces with temperature fluctuations, we advise fitting a weatherproof outer cabinet or choosing our IP65 range.

Q4: Does the lid have a provision for a padlock to prevent tampering?

A: The standard lid does not include a padlock hasp. However, we offer an optional locking kit that can be retrofitted. Without it, the magnetic catch provides basic security against casual opening.
