Yes — 347V is a standard single-phase voltage in Canada, derived from 347/600V three-phase wye systems commonly used in commercial and industrial buildings. It is widely used for lighting circuits and some HVAC branch circuits. The EDB16040's 347V, 1-pole rating makes it well suited to these Canadian commercial applications.
The EDB16040 is a bolt-on breaker, meaning it secures mechanically to the bus bar with a screw rather than snapping on. It cannot be interchanged with plug-in style breakers (such as Square D QO). You must confirm your panelboard accepts bolt-on EDB/ED-frame breakers before ordering — contact us with your panel model and we'll verify compatibility.
Availability can vary — some EDB-frame breakers move in and out of active production. Northern Breaker Group specializes in obsolete and hard-to-find breakers and maintains extensive inventory across our Calgary, Edmonton, and Vancouver locations. Reach out for a quote and we'll let you know current stock status or sourcing options.
