Relays

What is a Relay?

Relays are electrically operated switches that open and close circuits receiving electrical signals from external sources. The relays built into electrical products work in a similar way; they receive an electrical signal and send the signal to other equipment by turning the switch on and off. The three main functions of relays are to allow a small amount of electrical current to control high current loads, send different types of electrical signals, and drive multiple outputs with just one input.

Why Choose E. Preston?

We are an official distributor and wholesaler of relays from brands such as Crouzet, Crydom and Finder. These are well known companies in their fields with excellent reputations for the quality of their products.

What really sets us aside from our competition is our choice and range of relays – you really don’t need to look anywhere else for your requirements.

As we have been operating for over forty years, we have developed a fantastic relationship with our suppliers. This benefits us in two main ways: We gain access to the widest choice of components from those suppliers, and secondly, they sell us those components at competitive prices because we purchase such significant volumes. We are able to pass on those competitive prices to you, our customer.

We have a large stockholding of our products at our warehouse in Dukinfield, Cheshire in the UK. This stock means that our product availability is consistently high, and we can get your order for stock items out to you in a 24 to 48 hour time frame.
and we can talk through your specific relay requirements.

NR520R Receptable, NEMA-Mains Socket Outlet

  • High Performance 20 A / 125 VAC up to 150°C
  • Snap-In and IDC-Terminals efficient installations.
  • Available in black, white and grey
Schurter Nr520r

The Schurter NR520R mains socket outlet, as an additional variant to the NR010, NR020 and NR021 models, represents an even more powerful performance to the NEMA mains socket outlet portfolio. The new NR520R complies with UL 498 and CSA C22.2 no. 42.

The higher load capacity of 20 A at 125 VAC makes the NR520R particularly suitable for demanding applications where both high performance and temperature resistance up to 150°C are required. The NR520R mains sockets are ideal for applications in data centers, telecommunications, power distribution and energy management.

Simple Installation, Maximum Safety

The new NR520R power sockets from SCHURTER are designed for particularly efficient snap-in installation and can be wired particularly quickly and easily thanks to IDC and Quick Connect terminals. With these features, the NR520R combines the highest safety and performance standards with time-saving and user-friendly installation. This is particularly interesting for manufacturers of power distribution products. After all: safe, effective and efficient.

Black, White or Gray

The NR520R from Schurter is available in three different colors: black, grey and white. These color options not only offer aesthetic advantages, but also enable targeted adaptation to different environments and areas of application.
