Product FAQs
6 answersCan I install the FI36100 in a standard Square D QO or Homeline load center?
No, the FI36100 features an I-Line plug-on mounting style and is exclusively compatible with Square D I-Line panelboards and switchboards. It will not fit in standard residential load centers.
What is the modern replacement for the legacy FI36100 circuit breaker?
The FI36100 is a legacy F-Frame breaker. It can be substituted with the modern PowerPact equivalent, part number HRA36100U31X, which maintains the required I-Line mounting configuration.
What does it mean that the FI36100 is a current-limiting breaker?
As a current-limiting breaker, the FI36100 is designed to clear severe short circuits extremely fast, significantly reducing the peak let-through current and energy. This helps protect downstream electrical components from thermal and mechanical damage.
How does the FI36100 connect to the panelboard bus?
It features Square D I-Line plug-on mounting. The line-side jaws push directly onto the panelboard bus stack, and the breaker is then secured to the backpan with a captive mounting bracket screw, eliminating the need for individual bus cables or straps.
Can the FI36100 be used in DC power systems?
Yes, while primarily used in AC systems up to 600 VAC, this breaker is also rated for direct current applications up to 250 VDC, providing a 10 kA interrupting rating.
Are the trip settings on the FI36100 adjustable?
No, this breaker features a thermal-magnetic trip unit with fixed thermal and fixed magnetic settings. It provides standard Long-Time and Instantaneous (LI) protection without field adjustability.
