Yes — 347V is a standard voltage in Canadian commercial and industrial electrical systems. It is the phase-to-neutral voltage of a 600V, 3-phase, 4-wire (wye) distribution system, commonly used for commercial lighting circuits and branch distribution across Canada. The GBH1020 is specifically rated for this voltage, making it well-suited for Canadian commercial installations.
The GBH series is an older Eaton/Cutler-Hammer bolt-on line that can be difficult to source through standard distribution channels. Northern Breaker Group specializes in obsolete and hard-to-find breakers exactly like this one. Contact one of our Calgary, Edmonton, or Vancouver counter locations or request a quote online — we can often source units that others can't.
