Built for high-fault commercial and industrial applications, the FIL36060 is a 60A, 3-pole current limiting molded case circuit breaker. It mounts into Square D switchboards, individual enclosures, and motor control centers using standard feed-thru lug connections. Featuring a thermal-magnetic trip unit with long-time and instantaneous (LI) functions, it safely restricts let-through current during short circuits. This legacy F-Frame breaker is officially replaced by the HRL36060.

Product FAQs
7 answers
What equipment is the FIL36060 compatible with?
This unit-mount breaker is designed for use in Square D switchboards, motor control centers, and individual enclosures that accept legacy F-Frame breakers.
How is the FIL36060 mounted?
It features a unit-mount, feed-thru design. It secures directly to the backpan or mounting plate using screws rather than plugging onto a busbar, and connects to the circuit via standard lugs.
What wire sizes are accepted by the lugs on this breaker?
The standard lugs accept copper or aluminum wire ranging from 14 AWG to 1/0 AWG.
Does the interrupting rating change depending on the system voltage?
Yes. This breaker provides a 200kAIC rating at 240VAC and 480VAC, but the interrupting capacity drops to 100kAIC when applied to 600VAC systems.
What does the current-limiting feature of this breaker do?
As a current-limiting breaker with a 200kAIC rating at 480V, it is designed to clear high-level short circuits extremely fast. This reduces the peak let-through current and thermal energy to protect downstream equipment.
Is the FIL36060 still in active production?
The FIL36060 is a legacy F-Frame breaker. For new installations or direct replacements, Square D officially replaces this model with the PowerPact H-Frame HRL36060.
How does the thermal-magnetic trip unit operate?
The fixed thermal element provides long-time protection against sustained overloads, while the fixed magnetic element delivers instantaneous tripping to quickly clear short circuits.
