Product FAQs
10 answersWhat panelboards are compatible with the BDA260501?
This breaker is designed for use in Square D I-Line panelboards and switchboards. As a PowerPacT B-frame breaker, it serves as a modern replacement for legacy F-frame (FA and FH) breakers in I-Line panels.
What does the 1 at the end of the BDA260501 catalog number indicate?
The 1 indicates that this 2-pole I-Line breaker is factory-configured for an AB phase connection on the panelboard bus.
Can the BDA260501 be used on DC circuits?
Yes, this thermal-magnetic breaker is rated for use on DC systems up to 250VDC, where it provides a 10kA interrupting rating.
What wire sizes are accepted by the lugs on the BDA260501?
The factory-installed load-side mechanical lugs accept aluminum or copper wire ranging from 14 AWG to 2/0 AWG.
Does the BDA260501 have a push-to-trip feature?
Yes, like all PowerPacT B-frame breakers, it includes an integral push-to-trip button on the cover to manually trip the breaker and verify the mechanism is working correctly.
What older Square D breaker does the BDA260501 replace?
The PowerPacT B-frame BDA260501 is the direct modern replacement for the legacy 50A, 2-pole FA26050AB I-Line circuit breaker.
What is the continuous current rating of the BDA260501?
This breaker is standard-rated, meaning it is designed to be applied continuously at up to 80% of its 50A rating per NEC requirements.
How does the BDA260501 mount into the panel?
It features an I-Line style plug-in connection on the line side, which snaps directly onto the panelboard bus, and mechanical lugs on the load side for wire termination.
Are the trip settings adjustable on the BDA260501?
No, this breaker features a fixed thermal and fixed magnetic trip unit (LI functions), meaning the overload and instantaneous short circuit settings cannot be adjusted in the field.
What type of contact mechanism does the BDA260501 use?
All PowerPacT B-frame circuit breakers are equipped with dual-break rotating contacts. This design reduces the amount of peak current during a short circuit fault, lowering let-through energy and enhancing equipment protection.
