BDA160703 SQUARE D 1P 70A 347/600V B PH I LINE

The BDA160703 belongs to Square D's I-Line breaker family and is designed to plug into Square D I-Line panelboards and switchboards rated for 600V commercial/industrial use. It is not compatible with residential QO or Homeline loadcentres. Share your panelboard model with us and we'll confirm compatibility before you order.

Square D's BDA I-Line series breakers can be difficult to locate through standard distribution channels. Northern Breaker Group specializes in hard-to-find and obsolete breakers across Canada — contact our Calgary, Edmonton, or Vancouver counter or request a quote online and we'll advise on current availability, whether new, reconditioned, or equivalent.

The 14kA AIC (Ampere Interrupting Capacity) rating means the BDA160703 can safely interrupt a fault current of up to 14,000 amps at 347/600V. Before installation, your electrical engineer or qualified electrician should verify that the available fault current at the point of installation does not exceed this rating — this is a Canadian Electrical Code (CEC) requirement. If your system has higher available fault current, a higher-rated breaker will be required.
