347V is a standard single-phase voltage in Canadian commercial and industrial electrical systems, derived from a 600V three-phase supply (600V ÷ √3 ≈ 347V). This makes the FH17030B well suited for lighting and branch circuit protection in Canadian commercial buildings operating on 347/600V distribution systems.
