The BGA160503 SQUARE D 1P 50A 347/600V B PH I LINE is a high-performance circuit breaker designed for reliable protection in electrical systems. This single-pole breaker efficiently handles up to 50A and is ideal for both commercial and residential applications. Ensure safety and compliance with this durable and versatile component.
The BGA160503 is rated for 347/600V, which is the standard commercial and industrial three-phase wye voltage system used throughout Canada. The 347V single-pole rating means it is suitable for protecting 347V branch circuits — common in Canadian commercial lighting and HVAC systems — making it a code-compliant choice for those applications under the Canadian Electrical Code (CEC).
The BGA160503 belongs to Square D's BG-frame series, and other BG-frame breakers share the same mounting footprint. However, amperage, pole count, voltage rating, and interrupt rating (18kA in this case) must all match your application requirements. Always verify the exact replacement part number against your panelboard's breaker schedule before substituting. Contact our team and we'll help identify the right match.
Certain BG-frame Square D breakers can be difficult to source through standard distribution channels. Northern Breaker Group specialises in obsolete and hard-to-find breakers, and we maintain stock of legacy Square D commercial breakers. Reach out to our Calgary, Edmonton, or Vancouver counters for availability — we can also assist with sourcing reconditioned or new-old-stock units if required.
