Cutler Hammer contactors are used regarding moving equipment and mill applications, as well as for general purposes. They are used to start, stop, reverse, and regulate functions of a DC motor, as well as to control line insulation. Industrial duty contactors are rated 5A to 150A and can be used in any type of environment.
Process industries use contactors as a relay, electrical control, or to change a control or power unit. In the industry, they are shown as a unit where things such as liquid and air interact. There are many different sizes and forms of these devices made, each having different features and capacities.
Common applications of contactors are capacitor banks, lighting, heating, electric motors, and other electrical loads. The breaking current of a unit can go from a small number of amps and 24 V DE, to thousands of amps and kilovolts. Their size ranges from that of a teacup to those that have a side a yard wide.
Contactors have three parts. One part consists of auxiliary, power, and springs contacts. There is also an electromagnet, required to close the contacts, and an enclosure to protect them. The enclosure may be sealed, with insulating materials, or open-framed which must be protected from the elements. When more than 1000 volts are involved, they are protected with inert gas or a vacuum surrounding the contacts.
These units are very complicated in construction with varying parts, depending on the model. Some parts involved, for example, are a coil input, economizer circuit, and an energized coil. These are required for such things as keeping an energized coil cool, saving power, automatic acceleration control, and so forth.
cutler hammer contactors are used in all types of commercial and general power uses. They are used as a power control device, a starter point, or alone, and can be found in electric switches and very intricate industrial equipment. They are commonly labeled as a device to start and stop any electrical power circuit.
