Niglon PCU0604M Protego 4 Way Consumer Unit
100A Double Pole Main Switch – Compact Metal Consumer Unit
The Niglon PCU0604M Protego 4 Way Consumer Unit is a compact metal consumer unit designed for professional electricians carrying out smaller domestic installations, consumer unit replacements and dedicated electrical distribution projects. Featuring a factory-fitted 100A double-pole main isolator, twin-screw terminals and four usable outgoing ways, this 6-module enclosure combines practical circuit capacity with space-saving dimensions.
Part of the Niglon Protego range, the PCU0604M features durable powder-coated steel construction, a right-hand incomer, raised DIN rail and multiple cable entry positions. Its compact design makes it particularly useful where installation space is limited but a robust metal consumer unit is required.
The Niglon PCU0604M Protego 4 Way Consumer Unit is supplied without outgoing RCBOs or surge protection, allowing electricians to select suitable protective devices for their installation. It is compatible with the Niglon NSA2-240 Type 2 SPD, available separately from Electrical4Less.

Niglon Protego Range – Designed for Professional Electricians
The Niglon Protego consumer unit range combines robust steel construction with practical design features intended to simplify installation, conductor termination and maintenance.
The Niglon PCU0604M Protego 4 Way Consumer Unit benefits from a built-in spirit level, allowing electricians to position the enclosure accurately before fixing it to the mounting surface.
A raised DIN rail creates additional clearance for cable routing behind protective devices, helping installers organise conductors within the compact enclosure.
Multiple cable entry knockouts offer flexibility when routing incoming and outgoing conductors. Square rear knockouts are particularly useful during replacement installations where existing cables enter through the wall behind the consumer unit.
The Protego range also features accessible earth and neutral terminal arrangements, large terminal screws and a robust curved cover design.
These installer-friendly details help make the PCU0604M suitable for electrical contractors who require a practical metal enclosure without unnecessary additional circuit capacity.
Compact 4 Way Consumer Unit for Smaller Installations
The Niglon PCU0604M Protego 4 Way Consumer Unit provides four usable outgoing ways within a 6-module enclosure measuring 160mm wide, 240mm high and 110mm deep.
This compact arrangement is useful for electrical installations requiring a limited number of individually protected circuits.
Typical applications include:
- Smaller flats and domestic electrical installations.
- Garage and workshop distribution arrangements.
- Garden rooms and outbuildings with suitable indoor mounting conditions.
- Small domestic consumer unit replacements.
- Dedicated circuits for fixed electrical equipment.
- Suitable heating equipment supplies.
- Small commercial installations requiring limited circuit distribution.
- Ancillary distribution boards where four outgoing ways are sufficient.
The available ways can accommodate compatible Niglon protective devices selected according to the installation design.
The IP20 enclosure is intended for suitable indoor environments. Outdoor or exposed installations require an appropriately rated enclosure or additional protection.
Final circuit arrangements, conductor sizing and protective device selection must comply with the relevant requirements of BS 7671.
100A Double Pole Main Switch with Twin-Screw Terminals
The Niglon PCU0604M Protego 4 Way Consumer Unit incorporates a factory-fitted 100A 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 for incoming supply connections.
With a manufacturer-specified terminal capacity of 35mm², the main isolator accommodates suitably sized conductors when correctly terminated according to the manufacturer’s installation instructions.
The 100A rating refers to the rated main switch and consumer unit assembly. The actual supply characteristics, upstream protective device and conductor sizes must be assessed as part of the installation design.
SPD Compatible – Add the Niglon NSA2-240 Type 2 Surge Protection Kit
The Niglon PCU0604M Protego 4 Way Consumer Unit can be upgraded with the compatible Niglon NSA2-240 Type 2 Surge Protection Kit, available separately from Electrical4Less.
The NSA2-240 is a single-module Type 2 surge protection device designed to help protect connected electrical equipment against transient overvoltages associated with switching operations and indirect lightning-related events.
The device connects directly to the busbar in the compatible Protego consumer unit arrangement, without requiring a separate MCB.
Adding the single-module SPD to the standard PCU0604M occupies one of the four available outgoing ways, leaving three usable ways for compatible protective devices.
This provides a practical option for electricians who require surge protection but still want to select their consumer unit and protective devices separately.
Buy the Niglon NSA2-240 Type 2 Surge Protection Kit with Cables.
Please note: The standard PCU0604M is supplied without an SPD. The NSA2-240 must be purchased separately unless you choose the Electrical4Less SPD combination below.
Upgrade to Our Niglon Protego 3 Way SPD Consumer Unit
For electricians who prefer to purchase the consumer unit and surge protection together, Electrical4Less offers an exclusive SPD combination based on the original PCU0604M.
Our Niglon Protego 3 Way Main Switch SPD Consumer Unit (PCU0604M/SPD) combines the standard 4-way consumer unit with a compatible Niglon Type 2 SPD and a meter tails gland.
The standard board offers four outgoing ways. Once the included single-module SPD is installed, three usable outgoing ways remain for compatible RCBOs.
The SPD connects directly to the busbar and does not require a separate MCB in the specified arrangement.
This combination has been created by Electrical4Less using genuine Niglon components. It is not a separate factory-manufactured Niglon consumer unit model.
The Electrical4Less package includes:
- Niglon PCU0604M 4-way metal consumer unit.
- Factory-fitted 100A double-pole main switch.
- Compatible single-module Niglon Type 2 SPD.
- Meter tails gland for incoming supply cable entry.
- Three usable outgoing ways after SPD installation.
Outgoing RCBOs must be selected and purchased separately.

Compatible Niglon 6kA Bi-Directional RCBOs
The Niglon PCU0604M Protego 4 Way Consumer Unit is supplied without outgoing RCBOs, giving electricians flexibility when selecting individual circuit protection devices.
RCBOs combine residual current and overcurrent protection in one device, providing protection against residual current faults, overloads and short circuits when correctly selected and installed.
Using individual RCBOs can help minimise disruption by disconnecting the affected final circuit without necessarily interrupting other circuits.
Electrical4Less offers Niglon 6kA bi-directional RCBOs in a range of current ratings and tripping characteristics for compatible Protego consumer units.

Electricians must confirm protective device compatibility, current ratings, prospective fault current and disconnection requirements before installation.
