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.
This device is used for things such as heating, capacitor banks, lighting, electric motors, and other types of electrical loads. A breaking current can vary from a several amps with 24 V DC, to numerous kilovolts and many thousand amps. Their size ranges from that of a fist to ones having approximately a meter on one side.
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 varied. They can work alone, be used as a starter part, or as a power control device. They are used for a light switch or for industrial equipment. Their function is primarily to stop or start an electrical power circuit.
