The BDA161255 Square D 1P 125A Circuit Breaker is designed for high-performance electrical systems, operating at 347/600V. This unit features a compact design suitable for commercial applications and is ideal for protecting circuits from overload and short-circuit damage. Trust Square D quality for your critical power needs.
The BDA161255 belongs to Square D's I-Line plug-in breaker family and is designed to install in Square D I-Line panelboards and switchboards rated for 347/600V service — common in Canadian commercial and industrial installations. It is not compatible with residential QO or Homeline loadcentres. Contact us with your panelboard model number and we can confirm the fit.
The BDA frame series is an older Square D I-Line product line and can be difficult to source through standard supply channels. Northern Breaker Group specializes in obsolete and hard-to-find breakers — reach out to our Calgary, Edmonton, or Vancouver counters or request a quote online and we'll advise on current stock or suitable alternatives.
The BDA161255 carries a 14kA interrupting rating at 347/600V. Whether this is adequate depends on the available fault current at the point of installation, which must be calculated by a qualified electrician or engineer. If your system's available fault current exceeds 14kA, a higher-rated breaker will be required to meet Canadian Electrical Code (CEC) requirements. We can help you identify higher-interrupting-capacity alternatives if needed.
