Product FAQs
8 answersWhat panelboards are compatible with the BDA34080Y?
This I-Line plug-in circuit breaker is designed exclusively for use in Square D I-Line panelboards and switchboards.
What is the direct replacement for the discontinued FA34080 circuit breaker?
The PowerPacT B-Frame BDA34080Y is the designated replacement for the legacy F-Frame FA34080. It fits the same I-Line panelboard space and offers upgraded performance for retrofit applications.
How much mounting space does this 3-pole breaker require in an I-Line panel?
The 3-pole PowerPacT B-Frame circuit breaker requires 4.5 inches of I-Line mounting space, which equates to 1.5 inches per pole.
Can the BDA34080Y be used in DC voltage applications?
Yes, this breaker is dual-rated for AC and DC applications. It carries a DC interrupting rating of 10kA at 250VDC.
Are the trip settings adjustable on the BDA34080Y?
No, this breaker features a thermal-magnetic trip unit with fixed long-time and fixed instantaneous trip settings.
Is this breaker rated for 100% continuous loading?
No, standard PowerPacT B-Frame breakers like the BDA34080Y are rated for 80% continuous loading per NEC requirements.
Does this breaker feature a push-to-trip button?
Yes, all PowerPacT B-Frame circuit breakers include an integral push-to-trip button on the cover. This allows you to manually trip the breaker to verify the mechanical operation of the trip mechanism.
What type of contacts are used inside the PowerPacT B-Frame breakers?
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 currents and enhancing equipment protection.
