VS1-12kV/1600A Vacuum Circuit Breaker Technical Description The VS1-12kV/1600A is a high-performance vacuum circuit breaker (VCB) designed for medium-voltage applications, specifically rated for 12 kV systems with a continuous current capacity of 1600 A. It is widely used in power distribution networks, industrial plants, and commercial facilities due to its reliability, compact design, and advanced interruption technology. Key Features 1. Vacuum Interruption Technology - Utilizes a vacuum interrupter for arc extinction, ensuring minimal contact erosion and long service life. - The vacuum environment (10⁻⁶ to 10⁻⁷ bar) provides superior dielectric strength, enabling efficient interruption of high currents. 2. Rated Parameters - Rated Voltage: 12 kV - Rated Current: 1600 A - Short-Circuit Breaking Capacity: Typically 25–31.5 kA (depending on configuration) - Rated Frequency: 50/60 Hz 3. Compact and Modular Design - The VS1-12kV/1600A features a fixed or withdrawable design, allowing easy installation and maintenance in switchgear panels. - Its spring-operated mechanism ensures quick and reliable switching operations (open/close times < 50 ms). 4. High Mechanical and Electrical Durability - Mechanical endurance: ≥ 10,000 operations - Electrical endurance: ≥ 100 full-load interruptions - Robust construction with stainless steel or epoxy-insulated components for resistance to environmental factors. 5. Safety and Protection - Integrated overcurrent, short-circuit, and earth-fault protection (when paired with relays). - IP4X protection rating for dust and accidental contact prevention. 6. Environmental Compliance - SF6-free design, making it eco-friendly. - Complies with IEC 62271, ANSI C37.04, and other international standards. Applications - Power distribution substations - Industrial power systems (mines, manufacturing plants) - Renewable energy integration (solar/wind farms) - Commercial buildings and data centers Advantages - Low maintenance (no gas or oil replenishment required). - High breaking capacity with minimal arc energy. - Flexible integration with digital protection systems for smart grid compatibility. Conclusion The VS1-12kV/1600A vacuum circuit breaker is a robust, efficient, and sustainable solution for medium-voltage protection, combining cutting-edge vacuum technology with user-friendly operation.
