BDA160453 SQUARE D 1P 45A 347/600V B PH I LINE

The BDA160453 belongs to Square D's BDA (NF) frame series and is rated for 347/600V — the higher voltage found in Canadian commercial and industrial distribution. QO and Homeline breakers are residential-grade, typically rated 120/240V, and are not interchangeable with BDA-frame units. The BDA160453 is designed for 347/600V panelboards only.

Availability on BDA-series breakers can be limited as Square D has transitioned some product lines over the years. Northern Breaker Group specializes in obsolete and hard-to-find breakers — contact us and our team will check current stock, reconditioned units, or cross-reference an equivalent replacement if the original is no longer manufactured.

The 14kAIC (14,000 Amperes Interrupting Capacity) rating indicates the maximum fault current the breaker can safely interrupt. For many Canadian commercial distribution panels at 347/600V, this is adequate; however, installations closer to the utility source or with larger transformers may require higher AIC ratings. Always verify the available fault current at your panel with your electrician or engineer to ensure the breaker's rating meets CEC requirements.
