Product FAQs
5 answersWhat equipment is compatible with the FAP36020 circuit breaker?
The FAP36020 is a legacy F-frame molded case circuit breaker designed for use in Square D motor control centers and industrial panelboards. It utilizes a bolt-on connection and cannot be installed in standard residential QO or Homeline load centers.
Can the FAP36020 be used in direct current applications?
Yes, this thermal-magnetic breaker is suitable for DC applications. It carries a dedicated 250VDC rating, making it viable for specific industrial control circuits or battery systems.
What type of wire can be used with the FAP36020 lugs?
The factory-installed lugs accept both copper and aluminum conductors ranging from 14 AWG to 4 AWG. Ensure proper torque specifications are followed during installation to prevent terminal overheating.
Can the FAP36020 be reverse fed?
Yes, standard Square D F-frame breakers do not feature directional Line and Load markings. This allows them to be reverse fed safely when permitted by local NEC requirements.
Is the Square D FAP36020 still manufactured?
No, the FAP36020 is a legacy F-frame breaker that has been officially discontinued by Schneider Electric. It is primarily sourced to maintain or expand existing legacy panelboards without requiring a complete system upgrade.
