The Square D BDA140905 is a BDA-frame, 1-pole, 90A, 480V plug-in circuit breaker rated at 18kA interrupting capacity. The BDA frame is a commercial/industrial molded-case series designed for use in Square D I-Line panelboards and switchboards — it is not a residential QO or Homeline breaker. Its plug-in I-Line configuration makes it compatible with Square D I-Line panelboard interiors that accept plug-on BDA-frame breakers.
Panel fit depends on your specific I-Line interior and busway configuration. Send us your panelboard model number and we'll confirm compatibility.
The BDA-frame is a commercial/industrial molded-case breaker rated for 480V systems with an 18kA interrupting rating and I-Line plug-in mounting. QO and Homeline breakers are residential-grade, rated for 120/240V loadcentres only. The BDA140905 is not interchangeable with those residential types.
Square D has evolved its I-Line breaker lineup over the years, and some BDA-series variants can be difficult to find through standard distribution channels. Northern Breaker Group specializes in obsolete and hard-to-find breakers — contact our Calgary, Edmonton, or Vancouver counters and we'll source or cross-reference a suitable replacement for you.
The BDA140905 is suitable for use as either a branch or feeder breaker within a compatible Square D I-Line panelboard or switchboard, subject to your system's busbar rating, coordination study, and applicable Canadian Electrical Code (CEC) requirements. Consult a licensed electrician or engineer to confirm the correct application for your installation.
