Designed to protect commercial and industrial electrical systems, this 35A F-frame MCCB offers standard thermal-magnetic trip functions. It installs into Square D I-Line panelboards and switchboards, providing a 25kAIC rating at 240V and 18kAIC at 480V. The unit features Visi-Trip visual indication for quick fault identification and is HACR rated for HVAC applications. This legacy breaker is replaced by the newer PowerPacT H-frame HDA36035.
What panelboards accept the FA34035 circuit breaker?
The FA34035 is designed specifically for Square D I-Line panelboards and switchboards. It will not fit in standard residential load centers like QO or Homeline, nor will it fit in NQ or NF panels without a dedicated I-Line section.
What is the modern replacement for the legacy FA34035?
The FA34035 is a legacy F-frame breaker. Schneider Electric has replaced it with the newer PowerPacT H-frame series. The direct modern equivalent is the HDA36035, which maintains the 35-amp rating and I-Line plug-in mounting.
How is the FA34035 installed into the panel?
This breaker features an I-Line plug-in connection on the line side. It snaps directly onto the interior bus assembly of an I-Line panelboard using a specialized jaw mechanism, eliminating the need for line-side wiring. The load side utilizes standard mechanical lugs.
How does the FA34035 indicate a fault trip?
This breaker is equipped with Square D Visi-Trip visual indication. When a fault occurs, the handle snaps to a center tripped position and a red indicator window appears, allowing electricians to quickly locate the tripped breaker in a crowded panel.
Can this breaker be used for heating and cooling equipment?
Yes, the FA34035 is HACR rated. This means it has been tested and approved for the specific inrush currents and operational demands of heating, air conditioning, and refrigeration equipment.
What type of trip unit does the FA34035 use?
It utilizes a fixed thermal-magnetic trip unit. The thermal component provides long-time protection against overloads, while the magnetic component provides instantaneous protection against short circuits. Both the thermal and magnetic trip points are factory-fixed and non-adjustable.
Can the FA34035 be used in direct current (DC) systems?
Yes, unlike many standard AC breakers, the FA34035 is dual-rated for both alternating and direct current. It can be safely deployed in 250VDC applications, such as industrial DC control panels or battery systems, providing up to 10kAIC of fault protection.

Great company
Ordered on a Saturday evening, paid for two day shipping and it arrived on time and in perfect condition. Would 100 percent be using this company going forward, beat out pricing and shipping times for all my local supply houses. Plus the staff were great to deal with.

Professional Service
So far, so good! The circuit breaker was installed along with a new compressor for our church AC, and everything is now working well.
The company has been professional, dependable, and reputable throughout the process. I had a question after the installation, and it was answered immediately. I also appreciated that they followed up and asked for feedback to make sure the new part was working properly and that we were satisfied with the service.
It’s refreshing to deal with a company that not only has quality products but also cares about its customers after the job is completed. I would definitely recommend them!

As good as new
The Square D FA32100 circuit breaker (refurbished) was as good as a new breaker, without exception. There was no wear and tear or any marks at all. It was basically new. It is an excellent choice and a great product without having to pay the cost of a new breaker.
