The GE DTH series 100A fusible disconnect is designed to accept Class H and Class R (RK1/RK5) fuses up to 100A, 600V. Class R fuses are generally recommended for improved short-circuit protection. Always verify the required fuse class with your local electrical code (CEC) and application specifications before installing.

Yes — a NEMA 3R rating provides protection against rainfall, sleet, and the formation of external ice, making this disconnect appropriate for outdoor installations in Canadian climates. However, NEMA 3R is not dust-tight; for dusty or wash-down environments, a higher enclosure rating (such as NEMA 4 or 4X) may be required. Confirm your site conditions with your engineer or AHJ.
