FA26040AC **Old Style** - 40 Amp Circuit Breaker Description
FA26040AC **Old Style** - 40 Amp Circuit Breaker
If you're replacing an existing FA26040AC Old Style breaker, it's important to match the original specifications. This 40 Amp, 2-pole molded case circuit breaker is designed for use in compatible I-Line plug-in panelboards and features the original A-C phase configuration. It uses a thermal-magnetic trip mechanism that responds to both overloads and short circuits, helping to protect connected equipment and branch circuits during normal operation.
With an interrupting rating of 25kA at 240VAC and 18kA at 480VAC, this breaker is intended for 60Hz electrical systems and carries a HACR Type classification for compatible heating, ventilation, air conditioning, and refrigeration applications. The Old Style design is an important detail when replacing an existing breaker, since the physical configuration should match the equipment already installed.
