The W201K4CF contactor is a non-reversing contactor that belongs to the Eaton Cutler-Hammer Advantage series and the W201 class of contactors. This electrically operated contactor provides low voltage release for protection. The maximum Horsepower rating of the contactor is 40 Horsepower. The DeviceNet communication module, auxiliary contact module, bell alarm module, control wire ring/spade terminal block, and transformer pilot light kit are some of the accessories for this contactor that can be ordered separately. The W201K4CF non-reversing contactor also offers low-cost communication facilities to link ON/OFF commands, status, and motor data to automated control systems. The voltage and the frequency ratings of the coil are 120 Volts and 60 Hertz, respectively. The device weighs 6 pounds and it has 135 Amps of current. The W201K4CF contactor features a voltage rating of 200 Volts AC and a vibration resistance of 5 G. The ambient operating temperature range is 0 to 40 degrees Celsius and the ambient operating storage temperature range of -40 to 70 degrees Celsius. 

The W201K4CF non-reversing contactor is UL listed and CSA certified and it follows the NEMA standards to meet industrial requirements. Some of the features of the contactor include a small physical size, reliable communication capabilities, a long electrical life, and higher than average level of contact force. This compact device is 20% to 80% smaller than conventional devices and it uses smaller control panel boxes and enclosures than they do. It employs state-of-the-art technology to solve problems in motor control applications. Its communication facilities have the flexibility to interact and link with control systems for monitoring, controlling, and troubleshooting purposes. The W201K4CF non-reversing, electrically operated contactor is a microprocessor-based contactor and its “SURE” chip is the brain of the device. In order to use the contactor, the users must install a separate source of control power for it. It is recommended to supply the power from the motor supply circuit via a control power transformer. The W201K4CF contactor uses a magnet assembly component that is similar to the magnet assembly in conventional starters.
