Built for commercial distribution, the FAP36035 is a 3-pole, 35A molded case circuit breaker. It utilizes fixed thermal and magnetic trip elements for reliable overcurrent protection. Designed with a bolt-on mounting style, it fits into Square D motor control centers and panelboards. This legacy F-Frame unit is officially replaced by the HJP36035 for modern upgrades. Delivering an 18 kAIC interrupt rating at 480VAC, it features the signature Visi-Trip indicator.
Is the Square D FAP36035 still actively manufactured?
The FAP36035 is a legacy F-Frame molded case circuit breaker. For new installations or modern upgrades, Square D has replaced the F-Frame series with the PowerPact H-Frame family. Direct replacements typically include the HJA36035 or HJP36035, depending on your required interrupting capacity.
Will the FAP36035 fit into an I-Line panelboard?
No. The FAP36035 is a bolt-on circuit breaker designed for standard Square D panelboards and motor control centers. It does not have the plug-on jaw connections required for I-Line distribution panels. You must use an I-Line specific breaker for those enclosures.
Can I adjust the trip curve settings on the FAP36035?
No, the FAP36035 is built with fixed thermal and fixed magnetic trip elements. The long-time and instantaneous trip functions are factory set. If your application requires adjustable trip settings, you will need to upgrade to a breaker equipped with a Micrologic electronic trip unit, such as a modern PowerPact breaker.
How can I verify the mechanical linkage of the FAP36035 is functioning?
The breaker features a push-to-trip button on the front faceplate. Pressing this button manually trips the breaker, allowing electricians to verify the mechanical linkage is operating correctly and to exercise the mechanism during routine maintenance.
Does the FAP36035 require a specific wire material?
The factory installed lugs are dual rated for both copper and aluminum conductors. Ensure you use the correct torque specifications printed on the breaker faceplate when terminating either wire type to prevent overheating at the connection points.
