The HD13 Series Knife Switch is a heavy-duty manual isolating and control device from CHNAILE, designed for low-voltage power systems. It features a high-strength insulation structure, high-conductivity copper contacts, and a wear-resistant mechanical design, ensuring stable performance even under frequent operation. As an industrial load break switch, it is widely used in distribution cabinets, electrical control cabinets, and industrial equipment, providing reliable isolation and protection for electrical circuits.
The switch uses fiberglass-reinforced insulation boards, which enhance temperature resistance and mechanical stability. This prevents insulation breakdown in high-temperature or humid environments, ensuring user safety.
Its contacts are made of high-purity copper, which reduces contact resistance and improves heat dissipation. This minimizes energy loss and prevents contact overheating, ensuring long-term stable operation.
A precision mechanical linkage design ensures clear and reliable switching actions. The switch can withstand thousands of operations without wear, making it suitable for scenarios requiring frequent isolation (e.g., equipment maintenance).
Equipped with a multi-hole metal base plate, the HD13 Knife Switch supports multi-directional installation (horizontal or vertical) and is compatible with various distribution cabinet designs. This simplifies installation and reduces labor costs.
In industrial distribution boxes and electrical control cabinets, the HD13 Series acts as a manual isolator. Cutting off power safely during equipment maintenance or fault handling.
In the electrical control systems of mechanical equipment (such as machine tools and compressors) and automotive production lines. The switch is used to isolate local circuits, preventing accidental power-on during maintenance and protecting operators and equipment safety.
CHNAILE provides comprehensive customization for the HD13 Series Knife Switch to meet global industrial needs:
Current & Pole Customization: Adjustments to current ratings and pole numbers to match specific circuit requirements.
Mechanical Customization: Tailored terminal shapes and installation dimensions to fit customer’s distribution cabinet designs.
Branding & Packaging: Logo printing and custom packaging to support customer brand building in overseas markets.
Yes. It is a manual isolating device, with clear switching actions that ensure operators can confirm the circuit status intuitively—critical for safe maintenance.
The high-conductivity copper contacts reduce wear and heat damage, while the fiberglass-reinforced insulation board resists environmental aging, extending the switch’s service life.
While it is primarily designed for indoor use, customized versions with enhanced waterproofing can be provided for outdoor scenarios (e.g., outdoor power distribution stations), subject to customer requirements.
