Now in the third generation of family ownership E Preston Electrical continues to grow and build on traditional values.

“We work hard for our customers to get the best products at the best prices while providing exceptional customer service.  We always do what we say we will, even if that is just a call back,” says Mark Preston, MD.

This is a principle that was rooted in the business from its inception over 30 years ago by founder, and grandfather to the current directors, Ernest Preston.

Although there is still a great emphasis on these traditional values the company has embraced new technology in all of its business operations and now launches a new digital venture.  The new interactive e-shop eprestononline.co.uk is aimed at increasing accessibility to existing and new customers.

“We have access to the latest technology from our suppliers,” says Matthew Preston, sales director. “We want to make dealing with E Preston as easy as possible.  We will continue to visit new and existing customers, and speak to them on the telephone, but with eprestononline we can offer them access to our company whenever they want.”

Click AwayThe new eShop will allow customers to log in to their own portal to view orders, print off documents such as acknowledgements and invoices, and allows them to place repeat orders.  Data sheets and supplier catalogues will also be readily available.

The company believes it maintains its position as a traditional company – or more appropriately, a modern company with traditional values.

Crouzet Timers

crouzet1

A timer is a simple automation component which is used to manage actions over a period of time or control how long actions last.  The timer is a control device which triggers an action according to a time and a function.  After a predefined time has elapsed, the timer closes or opens one or more contacts. Timing cycles, whether single shot or repetitive, are started by latching inputs or pulsed inputs, allowing a wide variety of functions to be created.

Timers can be found in electrical cabinets associated with other automation functions for the following markets:

• Food industry
• Industrial automation systems
• Lighting
• Building equipment
• HVAC
• Small or large industrial machines

Schurter AEO 10.3×38 Fuse

Schurter Logo1.jpg

High Performance Fuse For Automotive Applications
• Very high rated current up to 50 A
• Safely interrupting 1000 VDC
• Versatile mounting options

With the AEO 10.3×38, SCHURTER launches a high-performance fuse for particularly high voltages up to 1000 VDC and currents up to 50 A, which is particularly suitable for automotive applications.

High voltages and high currents occur in electric vehicles in numerous places. Their battery packs with several thousand rechargeable cells store enormous amounts of energy. This in order to meet customer requirements concerning driving performance and range by still providing the shortest possible recharging times. To safeguard this level of power, you need highly reliable high power fuses. Such fuses are required, for example, in the BMS (Battery Management System), for on-board and off-board chargers, DC-DC converters and other systems exposed to high voltages.

Welding Is More Reliable
A weak point of every fuse is the connection between the melting wire and the contact cap. This connection is usually done by a solder joint. In the fuse production process, however, this technology brings quite many difficulties. Creating the connection by welding increases the reliability by far. SCHURTER uses a new, patented process which guarantees highest reliability.

Versatile Mounting Options
The new fuses of the AEO series offer a multitude of possible mounting options. In addition to the cartridge fuse, which requires a fuse clip (recommended model: SCHURTER CSO) and the classic mounting directly on a printed circuit board, screwable version for surface mounting or even axial mounting are available.

Applications Automotive:
DC/DC Converter, On Board Charger, Battery Management System, PTC-Heater and Houshold Charging Stations.

Schurter NEMA Receptacles 5-15R

Schurter Logo1.jpg

Convenience Outlets Redesigned
• NR010 – IDC for efficient wiring
• NR020 – The classic with improved temperature rating
• NR021 – Tamper Resistant

Schurter’s latest series of appliance outlets NR020 and NR021 combine classic features with new ones to meet increased fire protection and safety standards according to UL 498 Tamper Resistant, as well as facilitating compliance of receptacles used in Household and Commercial Furniture and Furniture Power Distribution Units (FPDUs), according to UL 962 and UL 962A. Higher temperature ratings and added configurations for series NR010 and NR020 respond to power demands facing Datacom infrastructures today.

Tamper Resistant Receptacles – TRR The concept of tamper-resistant receptacles is not a recent development; these devices have been a standard product offering of wiring device manufacturers for many years. The devices are designed to protect individuals (primarily children) from accidental shock resulting from the insertion of foreign objects. The US National Electric Code NEC® Article 406.12 states that all 15- and 20-ampere, 125- and 250-Volt nonlocking-type receptacles installed in dwelling units must be Tamper Resistant. In 2017, changes to the Code expanded on these requirements and locations. Previously, tamper-resistant receptacles were required in dwelling units, guest rooms and guest suites of hotels and motels, and in child care facilities. The expanded code brings these safety devices to preschools and elementary education facilities; business offices, corridors, waiting rooms and the like in clinics, medical and dental offices and outpatient facilities; to assembly occupancies such as places of awaiting transportation, gymnasiums, skating rinks, auditoriums; and to dormitories. These expanded locations are areas that small children frequently occupy.

Tamper resistant receptacles feature a UL recognized safety shutter system that prevents the insertion of foreign objects into a receptacle. The safety shutters will only open upon simultaneous insertion of two plug blades. Additional tests including Probe Test, Impact Test, Mechanical Endurance Test and Dielectric Voltage Withstand Test for Tamper Resistant Receptacles TRR are included in UL 498. After passing all the above performance tests, tamper-resistant receptacles must have either the words “Tamper Resistant” or the letters “TR” (minimum 3/16 inches high) on the device as a clear indication that this is a tamper-resistant receptacle.

Schurter’s NR021 NEMA 5-15R Tamper Resistant series meets the expanded code requirements according to UL 498. Additionally, with the option of an added insulated wall between the L, N terminals, compliance with the Spill Test, outlined in UL 962 Sec. 62, is more cost effective and efficient for manufacturers of Household and Commercial Furniture and Furniture Power Distribution Units (FPDUs).

Higher Temperature Rated Receptacles Packing density of equipment for data communication and storage continues to be regularly revolutionized with the surge of usage and functionality. Increasing ambient temperatures go hand in hand with these advancements, as demand trickles down to the smallest components to keep pace with emerging needs of the appliance manufacturers. The NR010 and NR020 series have an operating temperature range of -25 ˚C to 150 ˚C in response to the power needs of the Datacom industry. In addition, the NR010 with IDC terminals provides a version with an independent L terminal. The neutral and ground terminals can still be bussed, while the line terminal can be used for maximum load according to UL rating 15 A, 125 V. It also extends the capability of adding functionality to each outlet individually.
