Quality Assurance

As a company policy to ensure customer confidence products undergo third party certification and all active devices are 100% tested prior to shipping. Furthermore the manufacturing processes have been awarded ISO9001:2015 Quality System by the British Standards Institute for its design, manufacture and supply of electrical LV Switchgear.


As part of our UK testing facility, thermal testing of miniature circuit breakers and RCBO devices ensure our products meet the performance requirements of BS EN 60898.

Our range of RCD and RCBO devices undergo 100% electronic testing to ensure each device trips within the required time parameters. Each device is given a unique code following testing for complete traceability.


In the Proteus Industrial factory we have a purpose built, temperature controlled test room. This allows us to test our products at their rated current to ensure no problems occur. We have various current injection test sets, 3 phase and 1 phase, with a maximum output of up to 2500A.

Our current injection sets are continuously rated allowing us to test the products for many hours after the temperature steady state condition has been reached. This is far in excess of BS EN standards which require only temperature steady state to be achieved for 1 hour.


LV Switchgear

With increasing emphasis on energy conservation, Proteus Switchgear offers the complete range of intrinsic energy management, varying from timeswitch and relay logic to electronic microprocessor control* of lighting, heating and ventilation and fire/security systems.

Laser Cutting Machine

Once sheets of steel or copper are brought into the factory, the first process will be going through the CNC fibre laser machine. This machine cuts out all of our pre-programmed parts from the sheet material before they go on to the next step, bending on the press brake. 

Bespoke Units

In addition to our standard product range, we have the ability to offer fully bespoke units, tailored to customer needs to suit any individual installation.

Insulated, IP rated or metalclad units | Optional circuit control devices | Pre-wired short circuit protective devices | Fully tested assembly


CPD Certified Training Course

18th Edition Wiring Regulations

This presentation highlights the proposed significant changes to the 18th Edition Wiring Regulations, related to the protection of electrical equipment from electrical surges. It considers protection against voltage transients on the electrical installation only. Consideration should also be given to the protection against transient over-voltages transmitted by data transmission systems. BS EN 50174 refers.

BS EN 61439

BS EN 61439 is a series of standards to which LV switchgear manufacturers must comply. This course will explain what it is; the various parts; changes since the previous standard and how switchgear manufacturers comply with these new standards.


Case Study – Blackfriars

Rising up behind the Black Friars Inn, Salford, Manchester, itself a Grade II listed building now renovated as part of the project, are two striking towers of apartments as developed by M&E contractors Aberla M&E, part of the Aberla Group from Warrington.

Local Blackfriars, a Domis Construction led project consists of 380 luxury apartments, townhouses and top floor penthouses, plus a gym, café, cinema, launderette, a landscaped piazza area and commercial accommodation on the ground floor.
