Built for demanding industrial applications, this 15-amp, two-pole molded case circuit breaker provides essential thermal-magnetic protection. The PowerPacT B-Frame construction ensures durability while minimizing panel space. It mounts into standard I-Line panelboards and switchboards, and replaces older FA24015BC breakers to ensure a smooth transition for maintenance. Operating with a BC phase connection, it delivers an 18 kAIC rating at 480VAC and features dual-break rotating contacts.
What type of panelboards are compatible with the BDA24015Y4?
This breaker is designed exclusively for Square D and Schneider Electric I-Line panelboards and switchboards. It utilizes an I-Line style plug-in connection that mounts directly onto the panel's internal bus assembly.
What does the "Y4" suffix indicate on the BDA24015Y4 catalog number?
The "Y4" suffix designates a BC phase connection. When installed in an I-Line panelboard, this 2-pole breaker will draw power specifically from the B and C phases of the busbar.
What does the "D" in the BDA frame designation mean?
In the PowerPacT B-frame series, the second letter indicates the interrupting capacity tier. The "D" signifies an 18 kA interrupting rating at 480Y/277VAC and 25 kA at 240VAC.
Can the trip settings on the BDA24015Y4 be adjusted in the field?
No, this breaker features a fixed thermal and fixed magnetic trip unit. The Long-Time and Instantaneous (LI) protection parameters are factory-set and cannot be modified.
Is the BDA24015Y4 suitable for direct current (DC) systems?
Yes, this thermal-magnetic breaker is dual-rated for both AC and DC applications. It provides a 10 kA interrupting capacity for systems operating up to 250VDC.
What wire sizes are accepted by the standard lugs on the BDA24015Y4?
The factory-installed lugs on this 15A breaker accept either aluminum or copper wire ranging from 14 AWG to 2/0 AWG.
