Description
A reliable solution for high-capacity power distribution, the Square D FIL36050 is a 3-pole, 50A current limiting molded case circuit breaker. This legacy I-Limiter device restricts let-through energy during a fault, protecting downstream circuits from thermal stress. It features a unit-mount design suitable for Square D switchboards and standalone enclosures. With an exceptional interrupting rating of 200 kAIC at 480VAC, it meets rigorous demands. It is replaced by the PowerPact HRL36050.Specifications

Product FAQs
8 answersWhat enclosures or panels accept the FIL36050?
This unit-mount breaker is designed for installation in Square D switchboards, motor control centers, and individual enclosures that accommodate legacy F-frame breakers.
What does the current limiting designation mean for the FIL36050?
As a current-limiting breaker, it is engineered to clear a short-circuit fault in less than a half-cycle. This rapid response significantly reduces the peak let-through current and thermal energy, providing enhanced protection for downstream equipment.
What wire sizes and materials are supported by the factory lugs?
The included terminal lugs accept 14 AWG through 1/0 AWG copper or aluminum conductors. Ensure proper torque specifications are applied during installation as indicated on the breaker faceplate.
How is the FIL36050 mounted in a panel?
This is a unit-mount, feed-thru breaker. It bolts directly to the mounting pan or enclosure backplate and is wired via lugs, rather than plugging into a busbar like an I-Line breaker.
Is the Square D FIL frame still actively manufactured?
The FIL series is a legacy F-frame molded case circuit breaker. For new installations or direct upgrades, Schneider Electric has replaced this series with the modern PowerPact H-frame circuit breakers.
Can the FIL36050 replace an older FAL or FHL breaker?
Yes, the FIL36050 shares the same physical F-frame footprint as FAL and FHL breakers. Because the FIL is a current-limiting version with a much higher interrupting capacity, it serves as a direct physical replacement and a performance upgrade for high-fault applications.
What type of trip unit is equipped in the FIL36050?
It features a non-interchangeable thermal-magnetic trip unit with fixed long-time overload and fixed instantaneous short-circuit trip functions, designated by the LI trip code.
Does this breaker provide ground fault protection?
No, the FIL36050 is equipped with standard LI trip functions for thermal overload and short-circuit protection. It does not include integral ground fault or equipment protection features.
