Product FAQs
6 answersWhat type of panelboard is the FDA34030 designed for?
This breaker features an I-Line plug-on mounting style and is specifically designed for use in Square D I-Line panelboards and switchboards. It cannot be installed in standard load centers, NQ, or NF series panels.
Is the Square D FDA34030 an obsolete circuit breaker?
Yes, the Square D F-frame series is a legacy product that has been discontinued by Schneider Electric. The modern equivalent is the PowerPact H-frame series, specifically the HDA36030, which can be used as a direct replacement in I-Line panels.
How does the I-Line mounting system work on the FDA34030?
The breaker features built-in plug-on jaws that grip the panelboard busbars directly. It is then secured to the panel backpan using a retaining bracket and mounting screw, allowing for quick installation without individual wire connections to the bus.
What replacement lug kit is compatible with the FDA34030?
The standard mechanical lug kit for 15A to 30A Square D F-frame breakers is the AL50FA. This kit is used for terminating both copper and aluminum conductors on the load side.
Does the FDA34030 require external fuses to achieve its 18kAIC rating at 480V?
No, this is a standalone molded case circuit breaker. It achieves its 18kA interrupting capacity at 480VAC internally through its thermal-magnetic trip unit, without the need for upstream current-limiting fuses.
Can the FDA34030 I-Line breaker be reverse fed?
No. Because this is an I-Line breaker, the plug-on jaws are specifically designed to connect to the line-side busbars of the panelboard. The mechanical design dictates the direction of power flow, making reverse feeding inapplicable.
