Generac is proud to offer the first ever, CSA approved service rated transfer switches for Canadian use. These switches use patent pending technology to allow for use in whole house applications in Canada. The switches are available in 100 and 200 amp ratings for single phase applications. The switches employ CUL rated circuit breakers on the utility side of the transfer contactor for full downstream protection. The aluminum enclosure is rated for NEMA/UL Type 3R installation and is fully protected from the elements. Both transfer switches are housed in an aluminum NEMA/UL Type 3R enclosure, with electrostatically applied and baked powder paint. The Heavy Duty Generac Contactor is a UL recognized device, designed for years of service. The control at the generator handles all the timing, sensing and exercising functions. Features: • Electrically operated, mechanically-held contacts for fast, positive connections. • Rated for all classes of load, 100% equipment rated, both inductive and resistive. • 2 pole, 250 VAC contactors. • 160 millisecond transfer time. • Dual coil design. • Main contacts are silver plated or silver alloy to resist welding and sticking. • NEMA 3R (indoor/outdoor rated) aluminum enclosure is standard.
