Product Description
Product DescriptionVCBThe Vacuum Circuit Breaker (VCB) is a medium-voltage power switching and protection device designed for safe and reliable operation in electrical distribution systems. By using vacuum as the arc-extinguishing medium, the VCB provides fast arc interruption, high dielectric recovery strength, and excellent performance under frequent switching conditions.The VCB is equipped with a high-quality vacuum interrupter featuring a sealed-for-life design, which ensures long mechanical and electrical service life with minimal maintenance requirements. When coordinated with suitable protection relays, the breaker effectively protects power systems against short circuits, overloads, and abnormal operating conditions, enhancing overall system safety and stability.With a compact and robust structure, the VCB is available in both fixed and withdrawable types, allowing flexible installation in indoor metal-clad switchgear. The withdrawable version enables convenient inspection, testing, and replacement, improving operational safety and reducing downtime during maintenance. Its reliable operating mechanism ensures consistent opening and closing performance even in demanding environments.VCBs are widely used in medium-voltage applications such as substations, industrial facilities, commercial buildings, power plants, mining operations, and infrastructure projects. They are suitable for controlling feeders, transformers, motors, and capacitor banks.Manufactured in compliance with IEC 62271-100, the VCB offers high breaking capacity, excellent insulation performance, low operating energy, and environmentally friendly operation without the use of oil or SF6 gas, making it an ideal solution for modern medium-voltage power systems.| Arc-Extinguishing Medium | Vacuum |
