Low Voltage Knife Switch | HD11/HS11 Series, 4000A Breaking

Our low voltage knife switch is engineered with safety as a top priority. The switch provides visible isolation, ensuring that personnel can confirm the circuit is de-energized before performing maintenance. The contacts are made of high-conductivity silver alloy, which minimizes heat generation and prevents contact welding. The housing is arc-proof and flame-retardant, meeting international safety standards. We also incorporate a quick-make and quick-break mechanism to reduce arcing time, thereby extending contact life. Each switch is rigorously tested for dielectric withstand, temperature rise, and mechanical endurance, ensuring consistent performance. In real-world applications, our switches have facilitated safe maintenance in critical environments.

With 34 years of experience and exports to over 60 countries, we have developed deep expertise in diverse industrial requirements. Our low voltage knife switches are customized to meet local standards, such as CE in Europe, CCC in China, and specific voltage frequencies in other regions. We offer a wide range of accessories, including auxiliary contacts, padlock attachments, and extended handles, making integration into existing systems easy. Our R&D team collaborates with clients to develop unique solutions. For instance, we assisted a Chilean mining company to create a double-break switch for high-capacity motors, improving performance by 20%. We have also produced switches with colored handles for quick identification in complex installations, reducing operational errors.
