FA26050AB **Old Style** - 50 Amp Circuit Breaker Description
FA26050AB **Old Style** - 50 Amp Circuit Breaker
Keeping an existing electrical system in service starts with using replacement components that match the original specifications. The FA26050AB Old Style is a 50 Amp, 2-pole molded case circuit breaker built for compatible I-Line plug-in panelboards and features the original A-B phase configuration. If you're replacing an existing breaker in a legacy installation, this model provides the form, fit, and function needed to maintain the original panel layout without unnecessary modifications.
The thermal-magnetic trip mechanism responds to both overloads and short circuits, helping to protect branch circuits and connected equipment during normal operation.
