Why Choose the Square D FA36100?

The FA36100 combines Square D's trusted thermal magnetic technology with the convenience of a plug-in I-Line design. The long-time and instantaneous (LI) trip functions provide two-level protection: the long-time element guards against sustained overloads, while the instantaneous element reacts instantly to dangerous short-circuit events — protecting both equipment and personnel.

Ideal for use in industrial facilities, manufacturing plants, data centers, commercial buildings, and anywhere that demands dependable three-phase circuit protection at 600V.

I-Line Plug-In Connection – Fast, Reliable Installation

The I-Line plug-in design allows the FA36100 to connect directly to Square D I-Line panelboards without additional wiring to individual bus bars. This speeds up installation and replacement, and ensures a solid, low-resistance connection that meets Square D's strict manufacturing tolerances.
