No. The BDA140353 is an I-Line plug-in breaker designed for Square D I-Line panelboards and switchboards used in commercial and industrial applications. QO breakers are a completely different plug-in style intended for residential and light-commercial QO loadcentres. The two systems are not interchangeable. If you're unsure which breaker type your panel requires, contact our team with your panel model number and we'll point you in the right direction.
Northern Breaker Group specializes in obsolete and hard-to-find breakers. Whether the BDA140353 is current stock or a discontinued unit, we work to source it for you. Availability can vary, so we recommend reaching out for a quote — our Calgary, Edmonton, and Vancouver counters maintain extensive inventory of Square D I-Line breakers across multiple vintages.
The 18kA (18,000 amperes) interrupting rating is the maximum fault current the BDA140353 can safely clear without damage. For most commercial and light-industrial 480V distribution systems this rating is adequate, but you must verify that the available fault current at the point of installation does not exceed 18kA. If your system has a higher available fault current, a higher-rated breaker in the I-Line frame may be required. Contact us or consult a qualified electrician to confirm.
