The BDA34070 uses the Square D I-Line plug-in mounting system, making it compatible with Square D I-Line panelboards and switchboards (e.g., NQ, NF, and similar I-Line series enclosures). It is not designed for residential QO or Homeline loadcentres. If you're unsure whether your panel accepts I-Line plug-in breakers, send us the panelboard model number and we'll confirm compatibility.
18kA AIC (Ampere Interrupting Capacity) is suitable for many commercial and light industrial branch and feeder circuits on 480Y/277V systems where available fault current has been confirmed at or below that level. For installations with higher available fault current — common closer to large transformers or main distribution — a higher AIC-rated breaker may be required. We recommend verifying your system's available fault current with your engineer or utility before specifying.
Availability of specific I-Line frame breakers like the BDA34070 can vary. Northern Breaker Group specializes in obsolete and hard-to-find breakers, so even if this unit has been superseded or is difficult to source through standard channels, we can often locate new, reconditioned, or equivalent stock. Contact our Calgary, Edmonton, or Vancouver counter for a quote and lead-time estimate.
