Product FAQs
7 answersWhat panels are compatible with the BDA34050Y circuit breaker?
This breaker is designed exclusively for Square D I-Line panelboards and switchboards. It features a shrouded I-Line plug-on jaw on the line side and mechanical lugs on the load side.
Can the BDA34050Y be used to replace older Square D breakers?
Yes, the PowerPacT B-Frame is the designated replacement for legacy F-Frame breakers. The BDA34050Y serves as a direct drop-in replacement for the obsolete FA34050 I-Line circuit breaker.
How is the BDA34050Y mounted during installation?
The breaker uses an I-Line plug-on connection on the ON end (line side) that attaches directly to the panelboard bus. The OFF end (load side) features factory-installed mechanical lugs for wire termination.
What is the continuous current rating for this breaker?
The BDA34050Y carries a standard 80 percent continuous current rating. Per the NEC, it should be applied continuously at no more than 80 percent of its 50A rating.
What phase connection does this 3-pole breaker use?
The BDA34050Y is configured for a standard ABC phase connection on the I-Line bus.
What internal contact design does the PowerPacT B-Frame use?
It is equipped with dual-break rotating contacts. This design helps reduce the amount of peak let-through current during a short circuit fault, enhancing overall system protection.
Does the BDA34050Y include a manual testing mechanism?
Yes, it includes an integral push-to-trip button on the front cover. This allows electricians to manually trip the breaker to verify the mechanical operation of the trip unit.
