BDA141103 SQUARE D 1P 110A 480V B PH I LINE
The BDA141103 SQUARE D 1P 110A 480V B PH I LINE circuit breaker is engineered for reliable performance in high-demand environments. This single-pole breaker is designed to protect electrical circuits while ensuring optimal operation. Ideal for industrial applications, it guarantees safety and efficiency while supporting loads up to 110 amps at 480 volts.
"B PH" indicates this breaker is configured for the B-phase bus position, and "I LINE" refers to Square D's I-Line plug-in mounting system. This means the breaker uses Square D's I-Line jaw connector to plug directly onto a compatible I-Line panelboard bus, rather than requiring bolt-on connections. It's important to confirm your panelboard uses the I-Line bus system before ordering.
The Square D BDA-frame series is considered a legacy/hard-to-find product line. Northern Breaker Group specializes in sourcing obsolete and discontinued breakers across Canada. Whether new old-stock or a verified reconditioned unit is required, contact our Calgary, Edmonton, or Vancouver counter for current availability and to request a quote.
No. The BDA141103 is an industrial molded-case circuit breaker (MCCB) rated for 480 V AC and uses the I-Line plug-in mounting system. It is not designed or listed for use in residential loadcentres. It must be installed in a compatible Square D industrial panelboard or switchboard that accepts BDA-frame I-Line breakers at the appropriate voltage and bus ratings.
