Description
Features
- This heavy-duty double-throw switch functions as a reliable manual transfer or bypass mechanism, allowing you to instantly shift a 100 Amp load from one electrical source to another. It provides a foolproof method to isolate power supplies or bypass commercial solar inverter systems without the risk of dangerous backfeeding.
- Engineered for high-capacity applications, this 3-pole, 3-wire non-fusible disconnect effortlessly handles up to 600V AC/DC systems and is rated for up to 100 HP at 600V AC. This extensive power threshold ensures your heavy-duty industrial motors, commercial HVAC compressors, and high-voltage feeders operate safely under rigorous continuous duty cycles.
- The Square D F-Series engineering incorporates a precision quick-make, quick-break toggle mechanism that drastically reduces contact arcing and heat degradation. Built to significantly exceed standard NEMA KS-1 and UL98 endurance benchmarks, it guarantees decades of trouble-free maintenance isolation and emergency power disruption.
- Housed in a robust, surface-mounted NEMA Type 1 steel enclosure finished with a premium gray baked enamel coat, this switch provides superior physical protection for indoor facilities. Measuring 29.94 inches high by 11.96 inches wide, its streamlined profile provides ample internal wire-bending space while minimizing your structural footprint on crowded electrical walls.
- Outfitted with high-grade mechanical lugs, the terminal block accepts a wide installation range from AWG 14 to 1/0 copper or AWG 12 to 1/0 aluminum wiring. This flexible compatibility eliminates terminal overheating anxieties and allows field electricians to utilize existing on-site wiring without requiring expensive reducers or specialized crimps.
