Yes — a NEMA 3R fused disconnect switch like the HFC365R is commonly used as a service-entrance disconnect in Canadian outdoor applications, subject to CEC (Canadian Electrical Code) requirements for your jurisdiction. You'll need to confirm with your local authority having jurisdiction (AHJ) that the switch's ratings (400A, 600V, 3P) meet the specific service-entrance rules for your installation.
