The BDA160803 is a commercial/industrial plug-in breaker from Square D's BDA frame series. It is designed for Square D NQ, NQOD, and compatible I-Line panelboards rated for 347/600V — not residential loadcentres. Send us your panel model and we'll confirm the fit.
Availability of BDA-series breakers can vary. Northern Breaker Group specializes in obsolete and hard-to-find breakers, so even if this unit has been discontinued or has limited supply, we have extensive sourcing channels across Canada and internationally. Contact us or visit one of our Calgary, Edmonton, or Vancouver counters for a quote.
The 14kA AIC (Ampere Interrupting Capacity) rating means the breaker can safely clear a fault of up to 14,000 amps without rupturing. For many commercial 347/600V distribution panels in Canada this is adequate, but you must verify the available fault current at your panel against this rating. If your system's available short-circuit current exceeds 14kA, a higher-interrupting-capacity breaker will be required — our specialists can help you assess your options.
