Niglon Protego 23 Way Main Switch SPD Consumer Unit
PCU2824M/SPD – 100A Double Row Consumer Unit with Type 2 Surge Protection
The Niglon Protego 23 Way Main Switch SPD Consumer Unit is a large-capacity metal consumer unit combination designed for professional electricians carrying out domestic and suitable light commercial electrical installations. Featuring a 100A double-pole main isolator, Type 2 surge protection and 23 usable outgoing ways, this double-row board provides a practical solution for installations requiring numerous individually protected circuits.
Created by Electrical4Less, the PCU2824M/SPD package combines the original Niglon Protego PCU2824M consumer unit with a compatible Niglon single-module Type 2 surge protection device. A meter tails gland is also included, providing electricians with an additional installation accessory while allowing them to purchase outgoing RCBOs separately.
Electrical4Less Exclusive – Why 23 Ways Instead of 24?
The Niglon Protego 23 Way Main Switch SPD Consumer Unit is an Electrical4Less-created product combination rather than a separate factory-manufactured Niglon SPD consumer unit.
Niglon’s standard PCU2824M consumer unit provides 24 free ways within its 28-module double-row enclosure. As this particular board is not supplied by Niglon as a factory-packaged SPD configuration, Electrical4Less has created a convenient alternative by combining the standard consumer unit with a compatible single-module Type 2 SPD.
The SPD occupies one of the original 24 free ways, leaving 23 usable outgoing ways for compatible protective devices. This explains why Niglon’s original consumer unit specification refers to 24 ways, while the Electrical4Less PCU2824M/SPD package is advertised as a 23-way consumer unit.
The included surge protection device connects directly to the busbar in its specified configuration without requiring an additional MCB. This helps retain maximum circuit capacity while providing Type 2 surge protection.
Niglon Protego Range – Designed for Professional Electricians
The Niglon Protego range combines durable metal construction with practical installation features intended to assist electricians during consumer unit replacements, property rewires and new electrical installations.
The Niglon Protego 23 Way Main Switch SPD Consumer Unit benefits from the range’s spacious double-row arrangement, providing convenient access for outgoing circuit wiring and protective device installation.
The Protego range includes several installer-focused features:
- Built-in spirit level to assist with accurate positioning during installation.
- Raised DIN rails providing additional space for cable routing and termination.
- Multiple round cable entry knockouts for flexible installation arrangements.
- Square rear knockouts for cables entering from behind the enclosure.
- Robust 1.2mm curved steel cover construction.
- Accessible earth and neutral terminal arrangements.
- Large terminal screws designed for secure conductor termination.
- Powder-coated RAL 9010 white steel enclosure with rounded edges.
- Double-row configuration providing substantial outgoing circuit capacity.
These features are particularly useful when working with installations containing multiple circuits, where adequate conductor space, accessible terminations and practical cable entry positions can help achieve a tidy installation.
23 Usable Ways for Larger Domestic Installations
The Niglon Protego 23 Way Main Switch SPD Consumer Unit offers 23 usable outgoing ways once the included single-module Type 2 SPD is fitted.
This configuration provides circuit capacity for larger homes, substantial property renovations and installations where numerous final circuits require individual protection.
Typical applications may include:
- Separate upstairs and downstairs lighting circuits.
- Multiple socket outlet circuits.
- Dedicated kitchen appliance circuits.
- Electric showers and suitable heating equipment.
- Utility room and laundry equipment supplies.
- Garage and outdoor electrical circuits.
- Additional dedicated circuits for fixed electrical equipment.
The double-row arrangement allows electricians to organise outgoing circuits across the available ways, while the included SPD occupies only one module within the original outgoing circuit capacity.
The final arrangement must be designed according to the installation requirements, protective device selection, circuit loading and applicable edition of BS 7671.
Type 2 Surge Protection Included
The Niglon Protego 23 Way Main Switch SPD Consumer Unit includes a compatible Niglon Type 2 surge protection device designed to help protect connected electrical equipment against transient overvoltages.
Transient overvoltages may occur due to electrical switching operations or indirect lightning-related events. These disturbances can affect electronic equipment such as televisions, computers, smart home controls, heating controls and other connected devices.
The supplied single-module Type 2 SPD is designed to connect directly to the consumer unit busbar without requiring a separate protective MCB in the specified arrangement.
This space-saving arrangement leaves 23 outgoing ways available for RCBOs while providing a convenient means of incorporating surge protection into the installation.
SPD installation, earthing arrangements and protective coordination must comply with the manufacturer’s instructions and the relevant requirements of BS 7671.
100A Double Pole Main Switch
The standard PCU2824M consumer unit incorporates a 100A double-pole main switch, providing a means of isolating the consumer unit assembly.
The main switch features a twin-screw terminal arrangement intended to provide secure termination of suitably sized incoming supply conductors when installed according to the manufacturer’s instructions.
The 100A main isolator is positioned within the designated incomer section of the consumer unit, leaving the remaining enclosure capacity available for outgoing circuits and the included surge protection device.
The suitability of the consumer unit and main switch must be assessed against the supply characteristics, upstream protective device, conductor sizing and overall installation design.
Meter Tails Gland Included
The Niglon Protego 23 Way Main Switch SPD Consumer Unit package also includes a meter tails gland for the incoming supply cable entry.
When correctly selected and installed, the gland helps achieve a neat and secure cable entry arrangement, making it a useful accessory during consumer unit replacements and new installations.
By including a meter tails gland with the original consumer unit and Type 2 SPD, Electrical4Less provides electricians with a convenient combination of components commonly required when completing a consumer unit installation.
Compatible Niglon 6kA Bi-Directional RCBOs
The Niglon Protego 23 Way Main Switch SPD Consumer Unit is supplied without outgoing RCBOs, allowing electricians to select individual protective devices appropriate for the installation.
RCBOs combine residual current and overcurrent protection within one protective device, helping limit the disruption caused by faults on individual final circuits.
Electrical4Less supplies Niglon 6kA bi-directional RCBOs in a selection of current ratings, allowing installers to choose suitable devices according to circuit loading, protective device characteristics and manufacturer compatibility requirements.
