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 ...

As an electric motor’s rotor turns in close proximity to the motor windings, a bucking voltage or back electromotive force (EMF) is generated. The back EMF (BEMF) generated across the start winding is ...

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 ...

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 ...

Sponsored by Rockwell Automation. New IEC and NEMA contactors improve flexibility for machine builders and operators. Global machine and equipment builders designing panels for global markets need to ...

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.

Schneider Electric South Africa, a leader in digital transformation for energy management and automation, has launched the TeSys Deca Advanced, an advanced contactor solution designed to revolutionise ...

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 ...
