Part of the legacy F-Frame series, this 15A current-limiting molded case circuit breaker provides high-capacity thermal-magnetic protection for commercial and industrial applications. It minimizes let-through energy to safeguard sensitive downstream equipment. This unit-mount breaker installs into standard Square D enclosures, switchboards, and panelboards. It serves as a replacement for older installations and is superseded by the HRL36015. Rated 200kAIC at 480V, it features Visi-Trip.

What type of mounting does the Square D FIL36015 use?
The FIL36015 is a unit-mount circuit breaker. It is designed to be hardwired and mounted directly to a backpan in Square D enclosures, switchboards, or panelboards, rather than plugging into an I-Line bus.
What wire sizes are compatible with the lugs on this breaker?
The factory-installed line and load lugs accept 14 AWG through 1/0 AWG copper or aluminum conductors.
What are the magnetic trip settings for the FIL36015?
This 15A thermal-magnetic breaker features fixed instantaneous protection with an AC magnetic hold setting of 275A and a trip setting of 600A.
Can the FIL36015 be used in direct current systems?
Yes, in addition to its 600 VAC rating, this F-frame breaker is rated for use in DC applications up to 250 VDC.
What does the L in the FIL prefix signify?
The L indicates that this is a current-limiting molded case circuit breaker. It provides an exceptionally high interrupting capacity, rated up to 200kA at 480VAC and 100kA at 600VAC.
What trip functions are included in this F-frame breaker?
It is equipped with a thermal-magnetic trip unit that provides fixed long-time and instantaneous overcurrent protection, commonly referred to as LI functions.
What equipment is this breaker designed to be installed in?
It is engineered for use in compatible Square D enclosures, switchboards, and panelboards that accept legacy F-frame unit-mount breakers.
Is the Square D F-frame series still the current standard?
The F-frame is considered a legacy molded case circuit breaker family. For new installations or modernizations, Square D typically utilizes the PowerPact H-frame series, though F-frame breakers remain essential for maintaining existing enclosures and switchboards.
