The Allen-Bradley 104-E190EN22 Reversing AC/DC Contactor is a 3-pole reversing contactor from the IEC 104 Contactors series by Allen-Bradley/Rockwell Automation. The 104-E190EN22 Contactor is built to save panel space. It offers significantly reduced weight and dimensions (it is up to 25% smaller than older standard contactor models) to save installation panel space and reduce installation costs. The 104-E190EN22 Contactor saves energy with its low power consumption requirements and efficient operation. It features an eco-friendly design and parts that meet the RoHS compliance rating and it has a wide range of accessories that can be used to enhance and refine its performance and provide flexibility. The 104-E190EN22 Contactor comes with 2 side-mounted snap-on auxiliary contact blocks and a side-mounted mechanical interlock as factory-supplied options. The auxiliary contact blocks are of the normally open and normally closed type, and they are used for supporting the low-power feedback wiring.

The Allen-Bradley/Rockwell Automation 104-E190EN22 Reversing Contactor’s factory-supplied mechanical interlock helps to provide a connection to side-by-side mounted contactors for supporting the reverse and forward wiring of industrial AC motors. The 104-E190EN22 Contactor has a 3-pole main contact design for wiring to a 3-phase power source. The poles are of the normally open type and they come with bolt-in type terminals for quick and effective field wiring. The 104-E190EN22 Contactor has an IP2X enclosure protection rating. This enclosure provides insulated housing for all of the contactor’s internal components (including current-carrying terminals and coils) and it prevents the users from touching electrical contacts. Per the IEC 60068-2-27/60068-2-6 standards, the 104-E190EN22 Contactor is designed to withstand most high-vibration and high-shock industrial conditions. It has a wide operating temperature range and can be installed at a very high altitude (up to 3000 meters above sea level) without de-rating. The 104-E190EN22 Contactor has a rated working temperature range between -40 degrees Celsius and 70 degrees Celsius.
