Product FAQs
8 answersWhat type of electrical panels accept the BGA34030Y?
This breaker uses an I-Line style plug-in connection, making it compatible with Square D I-Line panelboards and switchboards. Because it is a 3-pole B-Frame, it requires 4.5 inches of I-Line mounting space (1.5 inches per pole).
Are the thermal and magnetic trip points adjustable on this breaker?
No, the BGA34030Y features fixed thermal (overload) and fixed magnetic (instantaneous short circuit) trip settings. The magnetic hold current is 400A and the trip current is 600A.
What does the 'G' in the BGA34030Y catalog number indicate?
The 'G' designates the short-circuit breaking capacity tier within the PowerPacT B-Frame series. The G-tier provides a 35 kA interrupting rating at 480/277 VAC, which is higher than the standard D-tier (18 kA) but lower than the J-tier (65 kA).
What is the standard continuous current rating percentage for this breaker?
Like standard thermal-magnetic breakers under the National Electrical Code (NEC), the BGA34030Y is rated for continuous operation at up to 80 percent of its 30A capacity. It is not 100-percent continuous rated.
Can this breaker be used in DC applications?
Yes, the BGA34030Y is UL listed for DC applications up to 250 VDC, providing a short-circuit interrupting rating of 20 kA.
Does the BGA34030Y fit in standard Square D QO or Homeline load centers?
No, this is a PowerPacT B-Frame molded case circuit breaker designed specifically for I-Line bus systems. It will not fit in residential QO or Homeline enclosures.
What are the wire size limits for the lugs on the BGA34030Y?
The factory-installed mechanical lugs accept a wire range from 14 AWG up to 2/0 AWG for both aluminum (Al) and copper (Cu) conductors.
How does the BGA34030Y trip unit function during a fault?
It utilizes a thermal-magnetic mechanism (trip function code LI). The thermal element responds to prolonged overcurrents by heating up over time, while the magnetic element provides instantaneous protection against severe short circuits.
