Niglon PCU2824M Protego 24 Way Consumer Unit
125A Main Switch – 28 Module Dual Row Metal Consumer Unit
The Niglon PCU2824M Protego 24 Way Consumer Unit is a high-capacity metal consumer unit designed for professional electricians carrying out larger domestic installations, extensive rewires and suitable light commercial electrical projects. Featuring a factory-fitted 125A double-pole main isolator, right-hand incomer and 28-module dual-row enclosure, it provides 24 usable outgoing ways for individual circuit protection.
Part of Niglon’s installer-focused Protego range, the PCU2824M combines durable powder-coated steel construction with a spacious internal layout, raised DIN rails, built-in spirit level and multiple cable entry positions. Its double-row configuration provides considerable circuit capacity without requiring the width of an equivalent single-row arrangement.
The Niglon PCU2824M Protego 24 Way Consumer Unit is supplied without outgoing RCBOs or surge protection, allowing electricians to select appropriate protective devices. For installations requiring Type 2 surge protection, the board is compatible with the Niglon NSA2-240 SPD, or customers can choose our exclusive Electrical4Less 23-way SPD combination.

Niglon Protego Range – Designed for Professional Electricians
The Niglon Protego consumer unit range has been developed to provide electricians with durable metal enclosures and practical features that make installation, wiring and maintenance more straightforward.
The Niglon PCU2824M Protego 24 Way Consumer Unit benefits from the spacious double-row arrangement, providing ample capacity for outgoing circuits while helping installers organise conductors across the two DIN rails.
Raised DIN rails offer additional clearance for cable routing behind protective devices, particularly useful during larger electrical installations where multiple conductors enter the enclosure.
The built-in spirit level helps electricians position the consumer unit accurately before fixing it to the mounting surface. Multiple round knockouts provide flexibility for cable entry, while square rear knockouts accommodate conductors entering from behind the enclosure.
The Protego range also incorporates accessible earth and neutral terminal arrangements, secure terminal connections, edging strips and a robust curved steel cover.
These features can be particularly beneficial during consumer unit replacements where existing cable routes, available conductor lengths and mounting positions influence the installation.
24 Usable Ways for Larger Domestic Installations
The Niglon PCU2824M Protego 24 Way Consumer Unit provides 24 usable outgoing ways within its 28-module dual-row enclosure.
This configuration offers electricians considerable flexibility when planning individual circuit protection for larger properties containing multiple lighting, socket outlet and dedicated appliance circuits.
Typical applications include:
- Larger domestic properties and substantial residential rewires.
- New-build homes requiring extensive circuit distribution.
- Properties with multiple lighting and socket outlet circuits.
- Separate kitchen appliance and cooking equipment circuits.
- Electric showers and suitable heating equipment supplies.
- Utility room and laundry equipment circuits.
- Garage, workshop and outbuilding supplies.
- Dedicated circuits for selected fixed electrical equipment.
- Suitable light commercial electrical installations.
The dual-row design allows electricians to arrange outgoing circuits in a logical layout, assisting with identification, maintenance and future circuit alterations.
Where additional circuit capacity may be required, the Niglon PCU2824M Protego 24 Way Consumer Unit offers more flexibility than smaller single-row boards, subject to the available ways and installation design.
The final circuit arrangement, protective device ratings and conductor sizing must be determined in accordance with the relevant requirements of BS 7671.
125A Double Pole Main Switch with 50mm² Terminals
The Niglon PCU2824M Protego 24 Way Consumer Unit includes a factory-fitted 125A double-pole main isolator positioned on the right-hand side of the enclosure.
The main switch provides a means of isolating the consumer unit assembly and features a twin-screw terminal arrangement intended for secure termination of suitable incoming supply conductors.
Niglon specifies a main switch terminal capacity of 50mm², providing additional conductor capacity compared with smaller Protego models fitted with 100A main switches.
The consumer unit has a rated operational voltage of 230V AC and a rated frequency of 50Hz.
The 125A rating refers to the manufacturer’s rated main isolator and assembly capacity. Actual installation loading, upstream protection, conductor sizing and supply characteristics must be assessed by the electrician.
SPD Compatible – Add the Niglon NSA2-240 Type 2 Surge Protection Kit
The Niglon PCU2824M Protego 24 Way Consumer Unit is compatible with the Niglon NSA2-240 Type 2 Surge Protection Kit, available separately from Electrical4Less.
The NSA2-240 is designed to help protect connected electrical equipment against transient overvoltages associated with electrical switching operations and indirect lightning-related events.
Its compact single-module design connects directly to the busbar within the compatible Protego consumer unit arrangement, without requiring an additional protective MCB.
Adding the SPD occupies one of the original 24 free ways, leaving 23 usable outgoing ways for compatible circuit protection devices.
This is an important consideration when planning circuit capacity. Although the SPD does not require a separate MCB, the surge protection device itself still occupies one module position.
Electricians wishing to purchase the standard consumer unit and surge protection separately can order the compatible kit directly.
Buy the Niglon NSA2-240 Type 2 Surge Protection Kit with Cables.
Please note that the standard PCU2824M consumer unit does not include an SPD. The NSA2-240 must be purchased separately unless you choose our Electrical4Less SPD combination.
Upgrade to Our Niglon Protego 23 Way SPD Consumer Unit
For electricians who prefer a consumer unit package with surge protection included, Electrical4Less offers an exclusive combination based on the original Niglon PCU2824M.
Our Niglon Protego 23 Way Main Switch SPD Consumer Unit (PCU2824M/SPD) combines the standard 24-way consumer unit with a compatible Niglon single-module Type 2 SPD and a meter tails gland.
The original PCU2824M provides 24 free ways. Once the included Type 2 SPD is fitted, 23 outgoing ways remain available for compatible RCBOs.
The SPD connects directly to the busbar without requiring a separate MCB, making it a space-efficient surge protection arrangement.
This combination is created by Electrical4Less using genuine Niglon components. It is not a separate factory-manufactured Niglon consumer unit model.
The Electrical4Less package includes:
- 1 × Niglon PCU2824M 28-module, 24-way dual-row metal consumer unit.
- 1 × Factory-fitted 125A double-pole main isolator.
- 1 × Compatible Niglon single-module Type 2 SPD.
- 1 × Meter tails gland for incoming supply cable entry.
- 23 usable outgoing ways after the SPD is installed.
Outgoing RCBOs are not included and must be purchased separately.

Compatible Niglon 6kA Bi-Directional RCBOs
The Niglon PCU2824M Protego 24 Way Consumer Unit is supplied without outgoing RCBOs, allowing electricians to configure individual circuit protection according to the installation requirements.
RCBOs combine residual current protection with overload and short-circuit protection within a single device. Using separate RCBOs can help reduce disruption by disconnecting an affected circuit without unnecessarily interrupting other final circuits.
This arrangement can be particularly useful for larger domestic installations with multiple lighting, socket outlet and dedicated appliance circuits.
Electrical4Less supplies Niglon 6kA bi-directional RCBOs in a selection of current ratings and tripping characteristics for compatible Protego consumer units.

Protective devices must be compatible with the consumer unit assembly and selected according to circuit design, prospective fault current, required disconnection times and manufacturer instructions.
