Niglon PCU3632M Protego 32 Way Consumer Unit
125A Main Switch – 36 Module Dual Row Metal Consumer Unit
The Niglon PCU3632M Protego 32 Way Consumer Unit is a high-capacity metal distribution board designed for professional electricians working on larger domestic properties, extensive rewires and suitable light commercial electrical installations. Featuring a factory-fitted 125A double-pole main isolator, right-hand incomer and 36-module dual-row enclosure, it provides 32 usable outgoing ways for individually protected circuits.
Part of the Niglon Protego range, the PCU3632M combines durable powder-coated steel construction with installer-focused features, including raised DIN rails, a built-in spirit level, accessible terminal arrangements and multiple cable entry knockouts.
The Niglon PCU3632M Protego 32 Way Consumer Unit is supplied without outgoing RCBOs or surge protection, allowing electricians to configure the board with compatible protective devices. For installations requiring surge protection, it can be upgraded using the Niglon NSA2-240 Type 2 SPD or purchased as our exclusive Electrical4Less 31-way SPD combination.

Niglon Protego Range – Designed for Professional Electricians
The Niglon Protego consumer unit range combines robust steel construction with installation features intended to improve cable management, mounting accuracy and access to protective devices.
The Niglon PCU3632M Protego 32 Way Consumer Unit features a spacious double-row configuration, providing additional capacity for larger installations where numerous outgoing circuits must be accommodated within one enclosure.
Raised DIN rails create clearance for cable routing behind the protective devices, helping electricians organise conductors and access terminal connections. This can be particularly useful on substantial rewires where multiple circuits enter the enclosure from different directions.
The built-in spirit level assists with accurate mounting, while multiple cable entry knockouts provide flexibility for incoming supply cables and outgoing final circuits.
Square rear knockouts are useful when cables enter through the wall behind the consumer unit, particularly during replacement installations where existing conductor routes need to be retained.
The Protego range also features large terminal screws, accessible earth and neutral bars, a robust curved steel cover and a clean powder-coated finish.
32 Usable Ways for Large Residential Installations
The Niglon PCU3632M Protego 32 Way Consumer Unit offers 32 usable outgoing ways across its dual-row arrangement, providing substantial flexibility when designing installations with numerous final circuits.
This makes the board particularly suitable for larger properties where individual circuits may be required for different areas, appliances and fixed electrical equipment.
Typical applications include:
- Large domestic properties and high-end 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.
- Utility room and laundry equipment supplies.
- Garage, workshop and outbuilding circuits.
- Dedicated supplies for selected fixed electrical equipment.
- Suitable light commercial installations requiring numerous outgoing circuits.
The dual-row configuration helps electricians organise larger numbers of outgoing circuits within a single consumer unit, potentially reducing the need for multiple separate enclosures where the installation design permits.
The final number of circuits, protective device ratings and circuit arrangements must be determined according to the installation requirements and BS 7671.
125A Double Pole Main Switch with 50mm² Terminals
The Niglon PCU3632M Protego 32 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 twin-screw terminals for secure termination of suitable incoming conductors.
Niglon specifies a main switch terminal capacity of 50mm², offering additional conductor capacity compared with smaller Protego models.
The PCU3632M has a rated operational voltage of 230V AC and a rated frequency of 50Hz.
The 125A rating refers to the manufacturer’s rated main switch and consumer unit assembly. It does not determine the required supply fuse rating or the permissible load of the installation. Supply characteristics, upstream protection, conductor sizing and thermal considerations must be assessed by the installer.
SPD Compatible – Add the Niglon NSA2-240 Type 2 Surge Protection Kit
The Niglon PCU3632M Protego 32 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 in the compatible Protego arrangement, without requiring a separate MCB for the specified configuration.
Adding the NSA2-240 to the original 32-way PCU3632M occupies one outgoing way, leaving 31 usable ways for compatible protective devices.
For electricians wishing to retain flexibility over SPD selection and installation, the surge protection kit can be purchased separately.
Buy the Niglon NSA2-240 Type 2 Surge Protection Kit with Cables.
Please note that the standard PCU3632M does not include an SPD. Surge protection must be purchased separately unless you choose our Electrical4Less SPD combination.
Upgrade to Our Niglon Protego 31 Way SPD Consumer Unit
For electricians requiring a large-capacity consumer unit with surge protection included, Electrical4Less offers an exclusive combination based on the original Niglon PCU3632M.
Our Niglon Protego 31 Way Main Switch SPD Consumer Unit (PCU3632M/SPD) combines the standard 32-way board with a compatible Niglon single-module Type 2 SPD and a meter tails gland.
The original PCU3632M provides 32 free ways. With the Type 2 SPD occupying one way, 31 outgoing ways remain available for individual circuit protection.
The supplied SPD connects directly to the busbar without requiring a separate MCB.
This exclusive Electrical4Less combination uses genuine Niglon components and is supplied as a convenient package rather than a separate factory-manufactured Niglon SPD consumer unit model.
The combination includes:
- 1 × Niglon PCU3632M 36-module, 32-way dual-row metal consumer unit.
- 1 × Factory-fitted 125A double-pole main isolator.
- 1 × Compatible single-module Niglon Type 2 SPD.
- 1 × Meter tails gland.
- 31 usable outgoing ways after the SPD is installed.
Outgoing RCBOs must be selected and purchased separately.

Compatible Niglon 6kA Bi-Directional RCBOs
The Niglon PCU3632M Protego 32 Way Consumer Unit is supplied without outgoing RCBOs, giving electricians the flexibility to select suitable circuit protection devices for the installation.
RCBOs combine residual current protection with overload and short-circuit protection in one device. Using individual RCBOs can help reduce disruption by disconnecting an affected final circuit without unnecessarily interrupting other circuits.
This arrangement is particularly useful for larger residential installations where individual protection may be required across numerous lighting, socket outlet and dedicated appliance circuits.
Electrical4Less supplies Niglon 6kA bi-directional RCBOs in a range of current ratings and tripping characteristics for compatible consumer unit installations.

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