Compatibility & Replacements
The 194E-GA20 /A is part of Allen-Bradley’s extensive Bulletin 194E load switch family, which shares operating handles and mounting configurations with the Bulletin 194L Control and Load Switches. Alternative models within the 194E series include the 194E-AA20E, 194E-CA20E, 194E-FA20E, and 194E-KA20E, each offering different enclosure types and voltage ratings (500 VAC to 600 VAC). When replacing or upgrading disconnect switches, verify voltage, amperage, pole count, and enclosure requirements match your application. The /A suffix indicates this is a later revision incorporating design improvements and enhanced reliability over earlier base catalog numbers.
