The Allen-Bradley 104-E146KD22L Large Frame Reversing Contactor is an IEC 104 series contactor with factory-supplied terminal lugs. The 104-E146KD22L Contactor works with low levels of power consumption and with a wide operating range to fit a wide range of applications. It offers an environmentally friendly design that complies with the RoHS standards. It is also designed to meet other relevant worldwide industry standards including the c-UL-us, CE, IEC, CSA, UL, CCC, EAC, and RCM standards. The 104-E146KD22L Contactor comes with a complete line of accessories that provide application flexibility. The 104-E146KD22L Contactor features a small design footprint (up to 25% smaller than standard contactors) to save panel space and application expenses. The 104-E146KD22L Contactor has a factory-rated operating temperature range of -40 to 70 degrees Celsius (-40 to 158 degrees Fahrenheit). It supports safe and reliable operation in conditions with high levels of vibration and shock (per the IEC 60068-2-6 standards) and can be installed at a maximum altitude of 3000 meters. The 104-E146KD22L Contactor supports an insulated IP2X environmental enclosure that houses the internal components and provides a degree of protection for both the users and the electrical equipment.

The Allen-Bradley 104-E146KD22L Large Frame Reversing Contactor from the IEC 104 series is designed to accept either AC or DC input voltage as required by the application. It has 3 Normally Open (NO) main power contacts or poles that are labeled from L1 through L3 and that are used for the wiring to the power source. It also has a factory-supplied side-mounted mechanical interlock that does not have any normally closed auxiliary contacts which is used for connecting 2 contactors with the same kind of frame together. The 104-E146KD22L Contactor supports reversing contact connections, and by jumping the input wires from one contactor to another, the operators can achieve forward and reverse switching for AC motors. The 104-E146KD22L Contactor comes with 2 factory-supplied side-mounted auxiliary contacts with a snap-in design. These contacts include 1 normally open contact and 1 normally closed contact and they are used for hosting the low-power feedback wiring.
