The BGA161251 Square D 1-Pole Circuit Breaker is designed for reliable performance with a 125A capacity at 347/600V. Featuring a compact design for efficient space utilization, this breaker is ideal for high-load applications. Perfect for commercial or industrial use, it ensures safe and effective protection for your electrical systems.
The BGA161251 uses Square D's I-Line plug-in mounting system, making it compatible with Square D I-Line panelboards and switchboards rated for 347/600V commercial and industrial service. It is not interchangeable with QO or Homeline residential loadcentres. Send us your panelboard model number and we'll confirm compatibility.
Yes — the 347/600V voltage rating makes this breaker well-suited for Canadian commercial and industrial installations, where 347V (phase-to-neutral on a 600V system) is the standard for lighting and other single-phase branch circuits. Always verify your system voltage and panel ratings with your licensed electrician to ensure full CEC compliance.
Availability can vary as Square D periodically updates its I-Line product lineup. Northern Breaker Group specialises in obsolete and hard-to-find breakers, so even if the BGA161251 has been superseded or is difficult to find, we can often source new, reconditioned, or equivalent units.
