Phoenix Contact's Contactronfamily of solid-state contactors now includes reversing and non-reversingcontactors in a variety of amperages. The contactors can activate or reverse 1-to 18.5 kW-powered ...

When voltage sags occur inside or outside of a facility, properly placed power quality mitigation technology will save sensitive equipment from costly shutdowns. The cost of this mitigation equipment ...

The Contactron solid-state reversing contactor from Phoenix Contact combines four functions in a module that’s just 22.5 mm wide (see the figure). Designed for three-phase ac motors up to 4 kW/5 HP in ...

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.

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 ...

Motor control centers (MCCs) were first introduced in 1937 as a way to conserve wall and/or floor space in industrial facilities. Before 1960, wall-mounted motor starters were used even if only a few ...

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 ...

It is often necessary for persons other than licensed electricians to perform minimal electrical work in a commercial or industrial facility. This work must be performed in the same safe manner as all ...

The automaker says defective contactors in its electrical motors could come loose, resulting in a loss of power. Lucid previously recalled its luxury Air sedans over a faulty wiring harness connected ...
