The Allen-Bradley/Rockwell Automation 104-E146EN22L contactor is a reversing type of contactor that has built-in terminal lugs. It is a specialized version of the basic 104-E146EN22 contactor, which does not have built-in terminal lugs. The 104-E146EN22L reversing contactor with built-in terminal lugs is part of the Allen-Bradley IEC 104 Contactors series, specifically part of the 104-E product line of 3-pole reversing contactors that run on AC and DC voltage. The 104-E146EN22L reversing contactor is a 3-pole contactor because it has 3 normally open contacts that it uses to host its power source connections. It also has a normally open auxiliary contact and a normally closed auxiliary contact for making other kinds of connections, and its special built-in terminal lugs make it easy to connect this contactor to a variety of terminals that it could not otherwise connect to. 

The Allen-Bradley/Rockwell Automation IEC 104 series 104-E146EN22L reversing contactor can operate with 146 Amps of current at 400 Volts in AC-3 applications and it can operate with 225 Amps of current at 690 Volts in AC-1 applications. It can be installed in a mechanical interlock device along with another contactor in order to operate in the reversing mode. When the 104-E146EN22L reversing contactor is installed in a mechanical interlock device, its dimensions are 150 millimeters in height, 180 millimeters in width, and 126 millimeters in depth. The electronic coil that is used by this reversing contactor is an AC/DC electronic coil with coil voltage ratings of 250 to 500 Volts AC with 50 to 60 Hertz frequency and 250 to 500 Volts DC.
