The Allen-Bradley 104-E146KD22 Large Frame IEC 104 Series Contactor is a 3-pole reversing contactor designed for large frame industrial applications. The 104-E146KD22 Contactor features a compact design with significantly reduced weight and dimensions that save panel space in installation. It also operates with low energy consumption levels and a wide operating voltage range that is made to suit a wide range of applications. The 104-E146KD22 Contactor features premium and eco-friendly components that are RoHS compliant. It also has an industrial design that meets several major industry standards such as the UL, IEC, and CSA standards. The 104-E146KD22 Contactor is built for high-vibration operating conditions per the IEC 60068-2-6 standards. It has an operating temperature range of -40 to 158 degrees Fahrenheit and a storage temperature range of -76 to 176 degrees Fahrenheit. The 104-E146KD22 Contactor comes with an enclosure with an IP2X ingress protection rating, which prevents the users from touching the contacts and suffering electric shock. This industrial enclosure also provides insulated housing to the current carrying contacts, coil, and other internal components of the contactor.

The Allen-Bradley 104-E146KD22 Large Frame IEC 104 Series Reversing Contactor can be wired to a 3-phase power source for standard operation. It supports both AC and DC input levels. The 104-E146KD22 Contactor specifically supports operating input voltage ranges from 115 Volts AC to 575 Volts AC with 50 to 60 Hertz frequency or 24 Volts DC to 440 Volts DC. It has 3 main contacts that are all the normally open type for wiring to the power lines. It also comes with line-side bolt-type terminals that support a direct bolt-in type of connection to the main power source. The 104-E146KD22 Contactor has 2 factory-installed auxiliary contacts (1 normally open and 1 normally closed) for low-power feedback wiring in addition to its 3 main contacts or poles. The users can order additional contacts and terminal lugs to meet specific application requirements. The 104-E146KD22 Contactor has a factory-supplied mechanical interlock device that allows for easy and secure reversing connections.
