Description
Part of the legacy F-Frame series, the FI36080 is an 80A, 3-pole molded case circuit breaker for commercial power distribution. It utilizes thermal-magnetic trip technology to ensure reliable protection. This current-limiting breaker mounts into Square D I-Line panelboards and switchboards. It includes load-side lugs and serves as a replacement for older systems, with the HRA36080 acting as its modern substitute. It delivers 200kAIC at 480VAC and features a Visi-Trip indicator.Specifications

Product FAQs
6 answersWhat types of panels are compatible with the FI36080 circuit breaker?
This breaker is designed for use in Square D I-Line panelboards and switchboards. It utilizes an I-Line plug-in mounting style for the line side connections.
What wire sizes do the lugs on the FI36080 accept?
The load-side lugs on this breaker accept copper or aluminum wire ranging from 14 AWG to 1/0 AWG.
Is the Square D FI36080 a current-limiting breaker?
Yes, it is a current-limiting molded case circuit breaker. It is rated to interrupt up to 200kA at 480VAC, which restricts let-through energy to help protect downstream equipment from high fault currents.
Can the FI36080 be used in DC electrical systems?
Yes, this breaker is rated for DC applications. It provides an interrupting capacity of 10kA at 250VDC.
What type of trip unit does the FI36080 feature?
It features a thermal-magnetic trip unit with fixed thermal and fixed magnetic settings. This provides standard Long-Time and Instantaneous (LI) trip functions for overload and short-circuit protection.
Is the FI36080 still in active production?
The FI36080 is part of the legacy Square D F-frame series. While still widely used, modern applications typically utilize Schneider Electric PowerPact B-frame or H-frame breakers as replacements.
