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 ...

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.

Arc flash is defined as an explosive release of energy caused by an electrical arc. Typically, the arc results from either a phase-to-ground or phase-to-phase fault created by many possible events.
