BDA160403 SQUARE D 1P 40A 347/600V B PH I LINE
The BDA160403 SQUARE D 1P 40A 347/600V B PH I LINE is a reliable single-pole circuit breaker designed for optimal performance in high-voltage applications. With a 40A current rating, it ensures effective protection for your electrical systems. Ideal for commercial and industrial settings, it provides peace of mind and safety for users.
The BDA160403 uses Square D's I-Line plug-in mounting system, which is designed for Square D I-Line commercial and industrial panelboards and switchboards. It is not compatible with residential QO or Homeline loadcentres. Contact us with your panelboard model number and we'll confirm it's the right fit.
The 347/600V rating is standard for Canadian commercial and industrial distribution systems — 347V is the phase-to-neutral voltage in a 600V three-phase wye system, widely used for lighting and mechanical loads across Canada. This breaker is specifically built for those higher-voltage applications and should not be used on standard North American 120/240V residential systems.
The BDA I-Line series can be difficult to source through standard channels, but Northern Breaker Group specializes in hard-to-find and obsolete breakers. We can help locate new, reconditioned, or compatible replacement options. Reach out to one of our counter locations in Calgary, Edmonton, or Vancouver — or request a quote online — and we'll track down what you need.
