Advice On Using Cutler Hammer Contactors
by Kelli Evans
A contactor is an electrical switch, which is similar to a relay. A contactor, however, handles much bigger currents and motors in terms of their voltage and horse power and give safe control, enabling switching and preventing arcing in powerful machinery and currents. Cutler hammer contactors are well suited to major commercial and industrial applications. Capacitors are the best switches for currents 15 amps and over, and deal with AC or DC motors to several kilovolts.
Cutler-Hammer has long been a name of repute in the manufacture of circuit breakers. Acquired by the Eaton Corporation of Cleveland Ohio in the late Seventies, the name is synonymous with safety in electrical applications. Eaton themselves have been in existence since 1911, and are a global giant, with annual sales of over sixteen billion dollars. Selling to more than 150 countries, they provide jobs for over 70,000 people and are a leading player in the power management sector.
For over a century, this company has been making industrial control tools. Harry H. Cutler and Edward W. Hammer created the Manufacturing Company back in 1893, when they began to specialize in speed regulators, field rheostats and electrical starters. Harry was the first inventor to patent the automatic motor starter at the very start of the twentieth century. The company designed all the control equipment for the Panama Canal in 1901. When rolled into Eaton, they brought half a billion dollars-worth of sales under one roof.
Their new Freedom series upholds the tradition, and offers freedom of choice when it comes to a contactor. You can now select a contactor, from this Freedom family, designed to IEC or NEMA standards. Both standards are international and highly regarded. This state-of-the-art product line is the only single family to offer both NEMA and IEC.
The company has been awarded the stringent ISO 9000 certification. This international standard for quality is recognized in over ninety countries worldwide. The International Standards Organization or ISO examines twenty elements in design, the production and then installation of the contactor, so they're truly amongst best, which is what anybody wants when purchasing a product that will have an important job.
The company's contactors are used in heavy industry, mining, telecommunications, quarrying, hospitals, schools and universities, office and retail building, major heating and lighting applications plus power-intensive machines such as escalators and elevators. They protect circuits from surges, arcs and damage from lightning strikes, outages in power, electric motor wear and utility switching.
A reversing plus a non-reversing contactor is available. A reversing contactor will reverse three-and single phase motors, with an electrically, also mechanically interconnected pair of contactors built in. This pair means there is no chance of energization or shorting out of both contactors at the same time. They'll handle as many as 3 million operations at 25 hp or 600 volts. These contactors meet NEMA standards.
Non-reversing <A href="http://www.lancocontacts.com">cutler hammer contactors</A> are magnetic, three phase AC motor switches. They run full voltage, and their starters feature both an overload relay and a contactor in one. The contactor is single: simply turning the motor on and off. It includes 3 switching terminals, with one for every phase.
