The Square D BGA160703 is a 1-pole, 70A, 347/600V plug-in circuit breaker from the BGA frame series, rated for 18kA interrupting capacity. This frame is designed for commercial and industrial panelboards and loadcentres that accept Square D BGA-series plug-in breakers — it is not a residential QO or Homeline unit. Its 347/600V rating makes it well suited to Canadian commercial distribution systems.
Compatibility depends on your specific panelboard's busbar and frame acceptance. Send us your panelboard model number and we'll confirm the fit.
The BGA160703 belongs to Square D's BGA frame series and is intended for commercial/industrial panelboards that accept BGA-series plug-in breakers at 347/600V. It is not interchangeable with residential QO or Homeline loadcentres. Send us your panelboard model and we'll verify compatibility before you order.
The Square D BGA frame series is considered a legacy/hard-to-find product line. Northern Breaker Group specialises in sourcing obsolete and discontinued breakers — contact us for current availability and lead times, as stock can be limited.
The 347/600V rating is specific to Canadian commercial and industrial distribution, where 347V phase-to-neutral (on a 600V wye system) is the standard for lighting and branch circuits. This breaker is built for those higher-voltage systems and must not be used as a direct replacement for standard 120/240V residential breakers.
