Product FAQs
6 answersCan the BDA140203 replace older Square D FA frame breakers?
Yes, the PowerPacT B-Frame BDA140203 is a direct substitute for the discontinued FA14020B 1-pole circuit breaker in Square D I-Line panelboards.
How does the BDA140203 connect to the panelboard?
This breaker features a shrouded I-Line plug-on jaw on the line side for quick installation onto the panelboard bus, and a mechanical lug on the load side that accepts 14 AWG to 2/0 AWG aluminum or copper wire.
What does the D in the BDA140203 part number signify?
The D indicates the interrupting rating tier within the PowerPacT B-Frame family. For this model, it provides an 18kAIC rating at 480Y/277VAC and a 25kAIC rating at 240VAC.
Which phase is this 1-pole breaker configured for?
The BDA140203 is factory-configured for a B-phase connection on Square D I-Line panelboards and switchboards.
Does this breaker include a way to manually test the trip mechanism?
Yes, all PowerPacT B-Frame circuit breakers are equipped with an integral push-to-trip button on the cover, allowing you to manually trip the breaker for testing and maintenance.
What type of contact mechanism does the PowerPacT B-Frame use?
It utilizes dual-break rotating contacts, which help reduce the amount of peak current during a short circuit fault for enhanced system protection.
