Description
The TeSys Non-Fusible Disconnect Switch from Schneider Electric is a robust solution for safe and reliable motor disconnection, capable of handling up to 25 horsepower at 600VAC. Designed with three poles and a maximum current rating of 32A, this switch ensures efficient power distribution while prioritizing operator safety. Its high-performance construction makes it an essential component in various industrial applications, serving as a critical safeguard for equipment and personnel alike. Whether for new installations or system upgrades, this disconnect switch underscores Schneider Electric's commitment to quality and innovation in power solutions.
Features
- Custom-engineered to isolate electrical loads safely, this load-break switch functions as a reliable manual motor circuit protector and main panel disconnect. It allows plant technicians to completely make or break power circuits under full load conditions, providing a physical, visible break in the upstream power line to ensure safety isolation during machinery maintenance.
- Belonging to the heavy-duty TeSys LK4 product family, this 3-pole (3P) AC device handles a continuous operational current of up to 30 Amps (UL/CSA) / 32 Amps (IEC) at voltages reaching 600 V AC. It is engineered to comfortably isolate high-demand machinery, delivering heavy-duty motor protection ratings of up to 25 hp at 600V, 20 hp at 480V, and 10 hp at 240V.
- This non-fusible switch features a robust, compact frame capable of handling extreme electrical stresses without structural failure. It delivers a high short-circuit current rating (SCCR) of up to 100 kA when paired downstream with appropriate Type J overcurrent protection fuses, and features a rated short-time withstand current ($I_{cw}$) of 5.5 kA to maintain downstream infrastructure protection.Featuring a highly compressed layout with dimensions of approximately 4.92 x 3.13 x 2.52 inches (125 x 79.5 x 64 mm), this switch reduces required panel space by up to 25% compared to traditional models. Equipped with universal ring-terminal / lug connections, it complies fully with UL 98, CSA C22.2 No. 4, and IEC 60947-3 standards, guaranteeing standard approval for industrial service-entrance installations.
