Niglon Protego 7 Way Main Switch SPD Consumer Unit
PCU1008M/SPD – 100A Main Switch with Type 2 Surge Protection
The Niglon Protego 7 Way Main Switch SPD Consumer Unit is a compact metal consumer unit combination designed for electricians carrying out domestic installations, consumer unit replacements and suitable small electrical distribution projects. Featuring a 100A double-pole main isolator, Type 2 surge protection and 7 usable outgoing ways, this configuration provides individual circuit protection capacity within a practical 10-module enclosure.
Created by Electrical4Less, the PCU1008M/SPD package combines the original Niglon Protego PCU1008M 8-way consumer unit with a compatible Niglon single-module Type 2 surge protection device. A meter tails gland is also included, making it convenient for installers to purchase the main components together while selecting compatible RCBOs separately.
Electrical4Less Exclusive – Why 7 Ways Instead of 8?
The Niglon Protego 7 Way Main Switch SPD Consumer Unit is an Electrical4Less-created combination rather than a separate factory-manufactured Niglon SPD consumer unit.
The original Niglon PCU1008M is a 10-module metal consumer unit with 8 free ways and a 100A double-pole main switch. As Niglon does not offer this particular board as a standard factory-packaged SPD configuration, Electrical4Less has created its own package using the original consumer unit and a compatible Type 2 SPD.
The included single-module SPD occupies one of the original 8 free ways, leaving 7 usable outgoing ways for separately purchased protective devices.
The SPD connects directly to the busbar without requiring an additional MCB in this configuration, allowing the remaining seven ways to be used for outgoing circuits.
This explains why Niglon’s original PCU1008M datasheet identifies 8 free ways, while the Electrical4Less PCU1008M/SPD combination is advertised as a 7-way SPD consumer unit.
Niglon Protego Range – Designed for Professional Electricians
The Niglon Protego consumer unit range combines durable metal construction with practical features developed to assist electricians during installation, cable termination and maintenance.
The Niglon Protego 7 Way Main Switch SPD Consumer Unit benefits from the original PCU1008M enclosure’s compact dimensions of 232mm wide, 260mm high and 110mm deep. Its single-row arrangement makes it a practical option where fewer outgoing circuits are required.
Installer-friendly features across the Protego range include:
- Built-in spirit level to assist with accurate wall mounting.
- Raised DIN rail providing additional space behind protective devices for cable routing.
- Multiple round cable entry knockouts for flexible installation arrangements.
- Square rear knockouts for cables entering through the rear of the enclosure.
- 40mm side knockouts and 20mm/32mm top and bottom knockout options.
- Robust 1.2mm curved steel enclosure profile and matching cover.
- Short-turn cover screws to assist with cover removal and refitting.
- Accessible earth and neutral terminal arrangements.
- Large terminal screws designed for secure conductor retention.
- Powder-coated steel construction with a clean white finish.
- Right-hand main switch incomer arrangement.
These features are particularly useful for electricians carrying out replacement consumer unit installations where the existing cable entry positions, available wall space and cable lengths can affect the installation process.
7 Usable Ways for Smaller Electrical Installations
The Niglon Protego 7 Way Main Switch SPD Consumer Unit offers 7 usable outgoing ways after allowing for the included single-module Type 2 SPD.
Its compact design makes it suitable for smaller domestic electrical installations requiring individual circuit protection without the additional capacity of a larger consumer unit.
Potential applications include:
- Smaller residential properties and flats.
- Consumer unit upgrades where seven or fewer outgoing circuits are required.
- Separate lighting and socket outlet circuits.
- Dedicated circuits for suitable kitchen appliances.
- Small commercial premises requiring limited circuit distribution.
- Suitable workshop and ancillary electrical installations.
- Installations where a compact main switch consumer unit is preferred.
The available circuit capacity allows electricians to select suitable outgoing protective devices according to the installation requirements.
Final circuit arrangements, loading, protective devices and enclosure suitability must be assessed in accordance with BS 7671 and the manufacturer’s instructions.
Type 2 Surge Protection Included – Direct Busbar Connection
The Niglon Protego 7 Way Main Switch SPD Consumer Unit includes a compatible Niglon Type 2 surge protection device designed to help protect electrical installations and connected equipment against transient overvoltages.
Transient overvoltages can be caused by switching operations within electrical networks and indirect lightning-related events. These disturbances can affect sensitive electronic equipment, including televisions, computers, smart home systems, network equipment and appliances containing electronic controls.
The supplied Type 2 SPD connects directly to the Protego consumer unit busbar without requiring a separate protective MCB in its specified arrangement.
Because the SPD occupies only one module, the original 8-way consumer unit retains 7 usable ways for outgoing circuit protection.
The SPD must be installed according to Niglon’s instructions, including the required connection arrangement, conductor routing, earthing provisions and protective coordination.
100A Double Pole Main Switch with Twin-Screw Terminals
The original Niglon PCU1008M consumer unit incorporates a 100A double-pole main isolator, providing a means of isolating the consumer unit assembly.
The main switch is positioned on the right-hand side of the enclosure and features a twin-screw terminal arrangement for the incoming supply connections.
Niglon specifies a 35mm² main switch terminal capacity, 230V AC rated operational voltage and 50Hz rated frequency for the PCU1008M model.
The 100A rating refers to the manufacturer’s rated assembly and main isolator. Installation suitability must be assessed against the supply characteristics, upstream protective device, conductor sizes and applicable wiring requirements.
Meter Tails Gland Included
Electrical4Less supplies the Niglon Protego 7 Way Main Switch SPD Consumer Unit with a meter tails gland, providing a useful accessory for incoming supply cable entry.
When correctly fitted, the gland helps achieve a neat and secure cable entry arrangement, supporting a professional installation finish.
Including the meter tails gland alongside the consumer unit and Type 2 SPD means electricians can obtain these components together without needing to purchase the gland separately.
The supplied gland must be installed in a suitable enclosure entry and used with compatible conductors.
Compatible Niglon 6kA Bi-Directional RCBOs
The Niglon Protego 7 Way Main Switch SPD Consumer Unit is supplied without outgoing RCBOs, giving electricians flexibility to select individual protective devices appropriate for each final circuit.
RCBOs combine residual current and overcurrent protection within a single device. Providing individual RCBO protection can help minimise disruption by disconnecting an affected circuit without necessarily interrupting other circuits.
Electrical4Less supplies Niglon 6kA bi-directional RCBOs in a selection of current ratings, allowing electricians to choose devices according to circuit design, prospective fault current and manufacturer compatibility requirements.

Please note that outgoing RCBOs are not included in this package and must be purchased separately.
