The Hubbell Circuit-Lock® HBL13R89 is a standard-duty, non-fused motor disconnect switch built for outdoor and industrial applications where reliable isolation of single-phase equipment is essential. Housed in a rugged all-aluminium NEMA 3R flip-lid enclosure, it stands up to rain, sleet, and windblown debris — making it a dependable choice for rooftop HVAC units, outdoor compressors, pumps, and other motor-driven equipment rated up to 20 hp (18,000 W). The 30 A, 600V AC rating covers a wide range of commercial and industrial motor loads, while pressure terminal screw connections and back and side wiring options give installers flexibility in tight panel or junction box layouts. Terminals accommodate up to #10 AWG solid or stranded copper wire, and the toggle mechanism is rated for a minimum of 10,000 mechanical cycles — delivering long service life in demanding environments. CSA and UL listed for confidence on inspected installations across Canada.
