Product: 1PCS All-Copper 2P100A HK11 Load Knife Switch Key benefits Reliable heavy-duty switching: 2-pole, double-throw knife switch rated at 100 A for handling substantial loads without frequent replacement. Good conductivity and long service life: all-copper construction provides low electrical resistance for efficient power transfer and improved durability. Flexible circuit control: bidirectional reverse double-throw configuration lets you switch between two circuits or reverse connections safely and quickly. Corrosion resistance for varied environments: copper resists corrosion better than many alloys, helping maintain performance in different working conditions. Load protection and system stability: designed as an HK11 load switch to control and isolate loads, helping maintain stable operation of electrical systems. Key features and specifications Model: HK11 load switch Quantity: 1 PCS Poles: 2-pole (2P) Rated current: 100 A Type: Double-throw, bidirectional/reverse knife switch Material: High-quality copper (all copper components where specified) How it solves common problems Prevents overheating and voltage loss associated with poor conductors by using high-quality copper for all current-carrying parts. Simplifies manual changeover or isolation of circuits with a clear, mechanical double-throw action. Provides a robust physical switch for load control in installations where simple, dependable manual switching is required. Typical applications Industrial control panels and machinery for manual isolation or circuit selection. Electrical distribution and maintenance panels for load transfer or testing. Workshops, test benches, and repair facilities where reversible or alternate circuit connections are needed. Compatibility and installation notes Designed as a conventional 2-pole knife switch; suitable for installations that accept a 2P mechanical switch form factor. Install and secure according to local electrical codes and safe working practices. Ensure connections and mounting match the panel or enclosure configuration before energizing. What makes this product stand out Pure copper construction combined with the HK11 load-switch design gives a balance of conductivity, mechanical simplicity, and reliability for demanding switching tasks without adding electronic complexity.
