Product FAQs
5 answersWhat type of panelboards are compatible with the FH16030A?
This breaker is designed exclusively for use in Square D I-Line panelboards and switchboards. It utilizes the I-Line plug-in mounting system and will not fit in standard NQ, NF, QO, or Homeline load centers.
What does the A suffix in the FH16030A catalog number indicate?
The A suffix indicates that this 1-pole breaker is factory-configured for an A-phase connection. The line-side jaw is positioned to plug directly onto the A-phase bus of an I-Line panelboard stack.
Is the FH-frame series still manufactured, or is there a modern replacement?
The Square D F-frame series is a legacy product line. Schneider Electric has superseded these with the modern PowerPact B-frame series. When sourcing a direct replacement for the FH16030A, a 1-pole, 30A PowerPact B-frame I-Line breaker with an A-phase connection (such as the BGA140301) is typically used.
How is the FH16030A physically installed into the panel?
The breaker features an I-Line plug-on jaw on the line side that snaps directly onto the panelboard bus stack. It is then secured to the backpan using a mounting bracket or screw. The load side utilizes a standard mechanical lug for the branch circuit wire.
What does the LI trip function code mean on this breaker?
The LI designation indicates that the thermal-magnetic trip unit provides two specific types of protection: Long-Time (L) for standard overload conditions and Instantaneous (I) for short-circuit protection. Both the thermal and magnetic trip thresholds are fixed on this specific model.
