Product FAQs
8 answersWhat type of panelboards accept the FY14030A circuit breaker?
The FY14030A is designed exclusively for use in Square D I-Line panelboards and switchboards. It features a plug-in mounting style that connects directly to the I-Line bus assembly.
How is the FY14030A secured to the panelboard bus?
This breaker utilizes Square D's I-Line plug-in design. It is seated onto the bus bar using a flat-blade screwdriver in the mounting plate notch with a ratcheting action, then locked in place with a retaining screw.
What wire sizes and materials are compatible with the terminals on this breaker?
The factory-installed lugs accept 14 to 4 AWG copper (Cu) wire, or 12 to 4 AWG aluminum (Al) wire.
What are the specific interrupting ratings (AIC) across different voltages for the FY14030A?
This thermal-magnetic breaker provides an interrupting capacity of 18kA at 277VAC, 14kA at 240VAC, and 10kA at 125VDC.
What does the "A" suffix in the FY14030A catalog number signify?
For Square D 1-pole I-Line breakers, the "A" suffix indicates the unit is factory-configured specifically for an A-phase connection on the panelboard bus.
Is the FY14030A part of a current product line?
The FY series is a legacy F-frame molded case circuit breaker. It is primarily sourced as a direct replacement to maintain existing I-Line infrastructure without requiring panel upgrades.
What type of fault protection does the LI trip function provide?
The fixed thermal-magnetic trip unit includes Long-Time (L) and Instantaneous (I) functions. The Long-Time function protects against sustained overloads, while the Instantaneous function trips immediately during short circuits.
Can the FY14030A be used in DC power systems?
Yes, in addition to its AC ratings, this breaker is rated for use in direct current applications up to 125VDC with a 10kA interrupting capacity.
