The Square D 2510KO2 is a 3-pole manual motor toggle switch from the K Series, designed for direct on/off control of single and three-phase motors in industrial and commercial applications. Rated at 30 A and 600 V AC, it handles motors up to 10 hp at 460/575 V AC and 7.5 hp at 230 V AC — making it a reliable choice for controlling pumps, fans, compressors, conveyors, and other motor-driven equipment on Canadian job sites. The compact open-device profile (4.13 in H x 1.69 in W x 2.34 in D) and screw clamp terminals simplify panel integration and field wiring with AWG 14–10 copper conductors. UL Recognized (E42243) and CSA Certified (LR25490), the 2510KO2 meets the standards required for motor control installations across North America.
