Product FAQs
6 answersCan I use the BDA160251 to replace an older FA or FH series circuit breaker?
Yes. The PowerPacT B-frame is the modern, direct replacement for legacy Square D FA and FH series 1-pole circuit breakers. It maintains the same I-Line mounting footprint for easy retrofitting in existing panelboards.
What does the "D" in the BDA160251 catalog number signify?
The "D" indicates the interrupting rating tier of the PowerPacT B-frame circuit breaker. For this model, it signifies a D-interrupting tier, providing 25kA at 240VAC, 18kA at 480Y/277VAC, and 14kA at 600Y/347VAC.
How does this breaker connect to the panelboard bus?
The BDA160251 features an I-Line style plug-in connection. It uses a plug-on jaw that snaps directly onto the I-Line panelboard bus stack, allowing for faster installation compared to traditional bolt-on breakers.
Is the BDA160251 suitable for direct current (DC) applications?
Yes, this thermal-magnetic circuit breaker is rated for use in DC systems. It provides an interrupting rating of 10kA at 125VDC.
What type of wire can be used with the lugs on this breaker?
The factory-installed mechanical lugs accept both aluminum and copper (Al/Cu) conductors ranging from 14 AWG to 2/0 AWG.
Are the trip settings on the BDA160251 adjustable?
No. This breaker features a fixed thermal-magnetic trip unit, meaning both the long-time (overload) and instantaneous (short circuit) trip functions are factory-set and cannot be adjusted in the field.
