The BDA160401 Square D 1 Phase 40A 347/600V circuit breaker is designed for reliable protection and performance in industrial applications. This compact, high-efficiency breaker ensures optimal safety for your electrical systems, providing excellent overload and short-circuit protection. Ideal for heavy-duty usage, it meets industry standards for reliability and durability.
The BDA160401 is a plug-in breaker from Square D's BDA frame series, designed for industrial and commercial panelboards rated at 347/600 V. It is not compatible with residential QO or Homeline loadcentres. To confirm whether it fits your specific panelboard, contact our team with your panel model number and we'll verify compatibility.
The 347/600 V rating is standard in Canadian commercial and industrial electrical distribution, where three-phase 600 V systems are widely used. The 347 V figure represents the phase-to-neutral voltage of a 600 V wye system — common for lighting and motor circuits in larger Canadian buildings. This breaker is specifically engineered to handle those higher-voltage applications safely.
Availability can vary as Square D periodically updates its BDA frame lineup. Northern Breaker Group specialises in obsolete and hard-to-find breakers across Canada, so even if this unit is no longer in active production, we can often source new, reconditioned, or equivalent replacement stock.
