Motor Controls - Contactors/ Starters/ Overloads from Cutler-Hammer



So many Programmable Logic Controller (PLC) outputs hook up to motor contactors and starters that we thought it made sense to sell them.
We offer a variety of electromechanical motor control solutions for motors up to 20 - 300 horsepower at 480 volts.
You can choose from the Cutler-Hammer Freedom series IEC contactors and starters for lower horsepower solutions, the Fuji Electric line of motor controls for solutions up to 300 Hp, or the GH Series European-made contactors, overloads and motor starter/ protectors (also for lower horsepower solutions).

The Eaton Cutler-Hammer Freedom series of components are sized based on international ratings classifications. We carry IEC sizes A through F (roughly up to 20 Hp).
For higher horsepower motor control solutions, see the Fuji Electric line of motor controls.

Contactor
From Wikipedia, the free encyclopedia
Jump to: navigation, search

AC contactor for pump application.In semiconductor testing, contactor can also refer to the specialised socket that connects the device under test.
In process industries a contactor is a vessel where two streams interact, for example, air and liquid.
A contactor is an electrically controlled switch (a relay) used for switching a power or control circuit.[1] A contactor is controlled by a circuit which has a much lower power level than the switched circuit. Contactors come in many forms with varying capacities and features. Unlike a circuit breaker a contactor is not intended to interrupt a short circuit current.

Contactors range from those having a breaking current of several amps and 24 V DC to thousands of amps and many kilovolts. The physical size of contactors ranges from a device small enough to pick up with one hand, to large devices approximately a meter (yard) on a side.

Contactors are used to control electric motors, lighting, heating, capacitor banks, and other electrical loads.



Construction

Albright SPST DC contactor,
sometimes used in EV conversionsA contactor is composed of three different items. The contacts are the current carrying part of the contactor. This includes power contacts, auxiliary contacts, and contact springs. The electromagnet provides the driving force to close the contacts. The enclosure is a frame housing the contact and the electromagnet. Enclosures are made of insulating materials like Bakelite, Nylon 6, and thermosetting plastics to protect and insulate the contacts and to provide some measure of protection against personnel touching the contacts. Open-frame contactors may have a further enclosure to protect against dust, oil, explosion hazards and weather.

High voltage contactors (greater than 1000 volts) may use vacuum or an inert gas around the contacts.

Magnetic blowouts use blowout coils to lengthen and move the electric arc. These are especially useful in DC power circuits. AC arcs have periods of low current, during which the arc can be extinguished with relative ease, but DC arcs have continuous high current, so blowing them out requires the arc to be stretched further than an AC arc of the same current. The magnetic blowouts in the pictured Albright contactor (which is designed for DC currents) more than double the current it can break, increasing it from 600 A to 1,500 A.

Sometimes an economizer circuit is also installed to reduce the power required to keep a contactor closed; an auxiliary contact reduces coil current after the contactor closes. A somewhat greater amount of power is required to initially close a contactor than is required to keep it closed. Such a circuit can save a substantial amount of power and allow the energized coil to stay cooler. Economizer circuits are nearly always applied on direct-current contactor coils and on large alternating current contactor coils.

A basic contactor will have a coil input (which may be driven by either an AC or DC supply depending on the contactor design). The coil may be energized at the same voltage as the motor, or may be separately controlled with a lower coil voltage better suited to control by programmable controllers and lower-voltage pilot devices. Certain contactors have series coils connected in the motor circuit; these are used, for example, for automatic acceleration control, where the next stage of resistance is not cut out until the motor current has dropped.[2]
