Product FAQs
8 answersWhat type of enclosures accept the FAL14035 circuit breaker?
This unit-mount breaker is designed for installation in compatible Square D enclosures and switchboards that accommodate legacy F-Frame feed-thru breakers.
Can the FAL14035 be installed in an I-Line panelboard?
No. The FAL14035 features a feed-thru connection with terminal lugs on both ends. It does not have the plug-on jaw connections required for Square D I-Line panelboards.
What applications typically require a 1-pole 277VAC circuit breaker?
A 1-pole 277VAC breaker like the FAL14035 is commonly used in commercial and industrial facilities to protect 277V single-phase lighting and control circuits fed from a 480Y/277V three-phase system.
What wire sizes are compatible with the terminal lugs on the FAL14035?
The factory-installed lugs accept 14 to 1/0 AWG copper wire or 12 to 1/0 AWG aluminum wire. Ensure proper torque specifications are followed during installation.
How is a feed-thru breaker like the FAL14035 mounted?
Feed-thru circuit breakers are unit-mounted, meaning they are bolted directly to a backpan or mounting plate within the enclosure, rather than plugging into a busbar system.
Can the FAL14035 be used in DC control circuits?
Yes, in addition to its 277VAC rating, this breaker is rated for 125VDC applications with an interrupting capacity of 10kA.
Are the trip settings on the FAL14035 adjustable?
No. This breaker features a fixed thermal and fixed magnetic trip unit, providing non-adjustable long-time and instantaneous protection.
Is the FAL14035 part of a current or legacy product line?
The FAL series is a legacy F-Frame molded case circuit breaker. It is commonly sourced to maintain or repair existing Square D switchboards without needing to retrofit newer breaker frames.
