Providing superior overcurrent defense, the Square D FIL36100 is a 100-amp, 3-pole molded case circuit breaker from the legacy F-Frame family. It is equipped with a thermal-magnetic trip unit for commercial applications. The breaker mounts into Square D switchboards and standalone enclosures via a standard unit-mount configuration. When upgrading older panels, the PowerPact HRL36100 serves as the manufacturer replacement. It boasts a massive 200 kAIC interrupting rating at 480VAC.

Product FAQs
9 answers
Is the Square D FIL36100 still manufactured?
The FIL36100 is a legacy F-frame breaker that has been superseded by the PowerPact H-frame series. For applications requiring a direct replacement with the same 200kAIC interrupting rating at 480VAC, the PowerPact HRL36100 is the recommended manufacturer substitute.
What does the I in the FIL36100 catalog number indicate?
In Square D legacy F-frame nomenclature, the I designates a current limiting circuit breaker. This provides an exceptionally high interrupting rating of 200kAIC at 480VAC, making it suitable for distribution systems with high available fault currents.
Can the FIL36100 replace a standard FAL or FHL breaker?
Yes, the FIL36100 shares the same physical dimensions and unit mount configuration as other legacy F-frame breakers. It can serve as a direct drop-in upgrade for FAL or FHL models when a higher interrupting capacity is required by the system design.
What type of enclosures can accommodate the FIL36100?
This unit mount breaker is designed for installation in Square D switchboards, motor control centers, and individual enclosures configured for legacy F-frame breakers. It is not compatible with I-Line panelboards, which require specialized plug-on mounting brackets.
Are the lugs removable on the FIL36100?
Yes, the standard mechanical lugs on this feed-thru breaker can be removed or replaced in the field. The factory lugs accept 14 to 1/0 AWG copper or aluminum conductors. Always torque replacement lugs to the specifications printed on the breaker faceplate.
Does the FIL36100 provide ground fault protection?
No, this model features a standard thermal magnetic trip unit with long-time and instantaneous functions for overload and short circuit protection. It does not include integrated ground fault or equipment protection features.
Can the FIL36100 be reverse fed?
Standard thermal magnetic F-frame breakers can generally be reverse fed unless specifically marked Line and Load on the housing. Always verify the physical labeling on your specific unit before wiring it in a reverse feed configuration.
Will PowerPact H-frame accessories work on the FIL36100?
No, legacy F-frame breakers require specific F-frame internal accessories. Shunt trips, auxiliary switches, and undervoltage releases designed for the newer PowerPact series are not backwards compatible with the FIL36100.
Can I adjust the trip settings on the FIL36100?
No, the FIL36100 features a fixed thermal and fixed magnetic trip unit. Neither the long-time overload nor the instantaneous short circuit settings can be adjusted in the field.
