This chapter covers representative general-purpose relays used in the control circuits of most industrial, commercial, and consumer products. Relay names and terminology are in accordance with ...

This new range of AC and DC solid state switching devices is an ideal solution for switching resistive, slightly inductive and motor loads, thanks to the reduced size per unit - starting at only ...

Relays and contactors use a variety of technologies to switch signals and power connections. Many devices called relays use similar techniques and topologies, but the terminology can be confusing.

Over the years, control relays of various types have been used by the hundreds — even thousands — to control nearly every function in commercial and industrial processes. Today, many of those ...

In continuing to provide the protective relay market with the newest innovations for replacement units, Basler Electric is offering a microprocessor-based BE1-50/51B-230 as an exact plug and play ...

When designing equipment with switching functions, most engineers find that switching high currents and high voltages is a major problem. A solid-state solution may be possible, but it’s complex and ...

ABB has installed more than 700,000 SPACOM relays used for power system protection and reliable power system operation world-wide. With the older generation of relays now aging, ABB is developing new ...
