Product FAQs
7 answersWhat panelboards are compatible with the BDA24100Y4?
This I-Line style plug-in breaker is designed exclusively for use in Square D I-Line panelboards and switchboards. It cannot be used in standard QO or NQ load centers.
What does the Y4 suffix indicate on this breaker?
The Y4 suffix indicates that this 2-pole breaker has a factory-set BC phase connection for mounting onto the I-Line bus.
Can the BDA24100Y4 replace older Square D F-frame breakers?
Yes, this PowerPacT B-frame breaker is a direct upgrade and replacement for the legacy FA24100BC circuit breaker.
Are the lugs on the BDA24100Y4 rated for aluminum wire?
Yes, the factory-installed mechanical lugs are dual-rated for both aluminum and copper conductors, accepting wire sizes from 14 AWG to 2/0 AWG.
Can this breaker be used in DC power systems?
Yes, the BDA24100Y4 is dual-rated for AC and DC applications. It supports up to 250VDC with a 10kA interrupting capacity.
Does the interrupting rating change depending on the system voltage?
Yes, the AIC rating is voltage-dependent. It provides 25kAIC on 240VAC and 208Y/120VAC systems, but drops to 18kAIC when applied to 480VAC or 480Y/277VAC systems.
Are the trip settings adjustable on the BDA24100Y4?
No, this breaker features a fixed thermal magnetic trip unit. Both the long-time (overload) and instantaneous (short-circuit) protection settings are factory-set and non-adjustable.
