Eaton Cutler-Hammer W201 Contactors

The W201 Contactors are contactor devices manufactured by Eaton Cutler-Hammer. They use PWM control and digital microprocessors for control purposes. They are available in different specifications. They come with non-reversing, reversing horizontal, and reversing vertical variants. They are also available in different voltage ratings and available in different frame sizes, different current ratings, and different power ratings. The contactors use 24 Volts DC coil control which is safe and reliable according to global standards. The W201 Contactors can be operated in a temperature range between -40 and 149 degrees Celsius. The contacts can be used for 2 or 3-wire control. They are equipped with long-life silver nickel and silver tin oxide contacts which provide excellent conductivity and superior resistance to welding and arc erosion.

The W201 Contactors are mainly used for controlling squirrel-cage poly-phase motors. The contactor devices are available in compact sizes and they can fit even in small factory spaces. The contactors are available in NEMA sizes 1 to 6 and with 3-pole variants. These devices can also be mounted by using different enclosures. Some of the variants come with control transformers, local cover controls, auxiliary control modules, bell alarm modules, mechanical interlocks, remote electrical resetting, and different communication modules. The W201 Contactors from the Eaton family have set a new standard for motor control. They help to maintain constant coil power, regardless of the varying control circuit conditions. They help to eliminate coil burnout, contact chatter, and welding due to low-voltage or fluctuating control signals. The W201 Contactors are equipped with application-specific SURE chip processors. These devices can be operated at a maximum altitude of 2000 meters above sea level without derating.
