Description
Designed for heavy-duty electrical systems, the Square D FAL36050 is a 3-pole, 50A molded case circuit breaker. It operates safely up to 600VAC and 250VDC, providing essential thermal-magnetic protection. This unit-mount device uses standard line and load lugs, fitting perfectly into commercial control panels and switchboards. As part of the legacy F-Frame family, it is replaced by the PowerPact HGL36050. The breaker delivers an 18 kAIC rating at 480VAC and includes a Visi-Trip indicator flag.Specifications

Product FAQs
8 answersCan the FAL36050 be installed in an I-Line panelboard?
No. The FAL36050 is a unit-mount circuit breaker equipped with feed-thru line and load lugs. It lacks the plug-on jaw connectors required for I-Line panelboards. For I-Line installations, the FA36050 is the correct plug-on equivalent.
What size wire is accepted by the standard lugs on the FAL36050?
The factory-installed lugs accept a wire range of 14 AWG to 1/0 AWG for copper conductors, and 12 AWG to 1/0 AWG for aluminum conductors.
Does the FAL36050 breaker have adjustable trip settings?
No. This breaker uses a standard thermal-magnetic trip unit with fixed thermal (overload) and fixed magnetic (short-circuit) settings, providing basic LI (Long-Time, Instantaneous) protection functions without adjustable dials.
Is the FAL36050 still actively manufactured, or is there a direct modern replacement?
The FAL36050 is part of the legacy F-Frame series. For new installations or panel upgrades, Schneider Electric replaced this F-Frame with the modern PowerPact H-Frame series, specifically the HGL36050 for equivalent 50A applications.
What is the maximum short-circuit interrupting rating (AIC) of the FAL36050 at 480VAC?
The FAL36050 is rated for a maximum of 18 kAIC at 480VAC. If your system requires a higher interrupting capacity, you will need a higher-tier breaker such as the FHL series, which is rated for 25 kAIC at 480VAC.
How does the FAL36050 indicate that it has tripped due to a fault?
It features Square D's signature Visi-Trip indicator. When the breaker trips due to an overcurrent or short-circuit fault, the handle snaps to a distinct midpoint position and a red indicator flag appears, visually separating a fault trip from a manually turned-off breaker.
Can I field-install electrical accessories like a shunt trip or auxiliary switch into the FAL36050?
No. The legacy Square D F-frame circuit breakers do not accept field-installed electrical accessories. Any accessories, such as shunt trips or auxiliary switches, must be factory-installed. If your application requires field-installable accessories, you should upgrade to the modern PowerPact H-Frame series.
Is the FAL36050 suitable for use with HVAC equipment?
Yes, this circuit breaker is HACR rated (Heating, Air Conditioning, and Refrigeration), making it suitable for providing branch circuit protection for compatible commercial HVAC equipment.
