E. Preston (Electrical) Ltd has been a specialist distributor of electrical and electronic components since 1980, offering thousands of products to meet a wide variety of needs and applications.
But we do more than simply sell components — we have built a reputation as a company who do business the traditional and honest way. Paying attention to the simple things — like phoning people back when we say we will — has kept our customers coming back for over four decades.
Our staff are experts in their fields, we maintain appropriate stock levels, and all of our processes are fully computerised to ensure a smooth operation.
We also understand that business is carried out between people, not companies. We do the hard work to maintain relationships with our suppliers as well as our customers. That way everybody in every part of the supply chain is satisfied – from the manufacturer to the end consumer.
The company, which is still wholly owned by the Directors, is located on a modern industrial estate which lies six miles to the east of Manchester in the North West of England.

The connector system for quick, easy, and safe bus cabling and signal applications. It meets all the requirements of modern building installation.
Low-Voltage Technology These connectors are used to distribute signals in buildings, in parallel to the distribution of power. Mechanical coding and clear assignment with different colors facilitate assembly. Complex installations can be realized with just four basic components – from the sub-distribution unit to any point of use. The connectors come as male and female connectors complete with strain relief and can be used to connect any current type of cable.
The BST14 are designed according to the KNX manual.
The 5G2.5/4+2X1.5 flat cable with shielded bus, as per the KNX manual, is available for the combined distribution of energy and signals.

Electrification is advancing across all industries – from electric vehicles and charging infrastructure to energy storage, aerospace, and fuel cells. As a result, the demand for reliable protection mechanisms in high-voltage systems is increasing. With the new Pyrofuse-APO Series, Schurter launches a fuse technology that sets a new benchmark for safety.
Unlike conventional fuses, the APO Fuse operates actively. In the event of a short circuit or accident, the control unit sends a trigger signal to an integrated micro gas generator. Within milliseconds, the generator produces high pressure that drives a piston to mechanically sever the solid copper busbar. The resulting arc is safely suppressed in a dedicated extinguishing chamber. The outcome is a complete galvanic isolation in less than two milliseconds – with measured values as fast as 0.9 ms.
The APO Series is rated for operating voltages up to 1000 volts and continuous currents up to 400 amperes. With an ultra-low internal resistance in the range of only a few dozen micro-ohms, power losses and temperature rise remain minimal. Its high breaking capacity ensures safe interruption even under extreme short-circuit conditions, while the fully encapsulated design prevents the release of gases or particles.
This unique combination of speed, robustness, and efficiency guarantees maximum system safety. At the same time, the compact design allows for seamless integration into existing architectures and relieves downstream components such as contactors.
With the Pyrofuse-APO Series, Schurter strengthens its position as a technology partner for emobility and the energy transition. Whether in electric vehicles, aerospace applications, or stationary storage systems, the APO Fuse ensures that high-voltage systems remain reliably protected – even under the most demanding conditions.
