Product FAQs
8 answersWhat panelboards accept the BDA24050Y2 circuit breaker?
This B-Frame breaker is designed exclusively for Square D I-Line panelboards and switchboards. It features an I-Line style plug-in connection on the line side and cannot be installed in standard QO or Homeline load centers.
What does the "2" suffix indicate in the BDA24050Y2 part number?
For 2-pole PowerPacT breakers, the "2" suffix indicates that the breaker is factory-configured for an AC phase connection on the I-Line busbar stack.
What does the "D" in the BDA prefix represent?
The "D" indicates the interrupting rating tier for this PowerPacT B-Frame breaker. It provides an 18 kA interrupting capacity at 480VAC and 480Y/277VAC, as well as 25 kA at 240VAC.
Is the BDA24050Y2 rated for use in DC circuits?
Yes, this thermal-magnetic breaker is rated for DC applications. It provides an interrupting capacity of 10 kA at 250VDC.
What wire sizes and materials are supported by the load lugs?
The load-side mechanical lugs accept wire gauges ranging from 14 AWG to 2/0 AWG. They are rated for use with both aluminum (Al) and copper (Cu) conductors.
How is the BDA24050Y2 mounted in a panel?
It utilizes an I-Line plug-on jaw assembly on the line side that engages directly with the panelboard bus stack. The load side uses standard mechanical lugs for wire termination.
Can I adjust the trip settings on this breaker?
No, the BDA24050Y2 features fixed thermal and fixed magnetic trip elements (LI, Long-Time and Instantaneous). The trip points are factory-set and cannot be adjusted in the field.
Can the BDA24050Y2 replace older legacy breakers?
Yes, PowerPacT B-Frame I-Line breakers are designed to replace legacy Square D F-Frame breakers, such as the FA24050AC. They maintain the same 1.5-inch per pole width, allowing for direct substitution without requiring blank fillers.
