Product Description

Designed specifically for electrical equipment operating at 2.3kV~7.2kV, the MVC Series medium-voltage vacuum contactors can also handle motors with a maximum capacity of 7000HP under 6600V voltage.

Boasting a comprehensive product range, the MVC Series medium-voltage vacuum contactors fully meet various customer needs. They cover voltage ratings of 2.5kV, 5.0kV, and 7.2kV, with rated currents available in 200A, 400A, 600A, 800A, 1200A, and up to 3000A for single-pole configurations.The reversible terminal design allows for both same-side and opposite-side installation of incoming and outgoing wires, enabling quick on-site switching. Additionally, their ultra-long mechanical and electrical service life provides users with enhanced safety guarantees.The 7.2kV MVC vacuum contactors are widely used in power distribution systems and drive systems, such as power distribution cabinets, soft-start cabinets, and frequency converter cabinets. With a maximum three-phase current of 1200A and a maximum single-phase current of 3000A, they deliver maximum power for power plants. Complete phase-to-phase insulation, near-zero maintenance requirements, and ultra-long service life offer reliable guarantees for stable production. As one of the core components in frequency converter cabinets, the vacuum contactors also effectively contribute to energy conservation and efficiency improvement.

Feature

• Broad Voltage & Power Adaptability for Diverse Scenarios：Covers a rated voltage range of 2.5kV-7.2kV, perfectly matching electrical equipment in medium-voltage power systems. It also supports high-power motor control—under 6600V voltage, it can handle motors with a maximum capacity of 7000HP, eliminating the need for separate product selection due to voltage or power differences. This makes it suitable for power plants, industrial distribution networks, and renewable energy facilities.

• Multiple Current Ratings to Meet Varied Load Demands:Offers a wide range of rated current options, including 200A, 400A, 600A, 800A, and 1200A for three-phase configurations, while single-pole models can reach up to 3000A. From medium-capacity circuit switching (e.g., 200A for small industrial pumps) to high-power drive systems (e.g., 1200A/3000A for power plant main circuits), it flexibly adapts to different load requirements.

• Reversible Terminal Design for Flexible Installation:Features reversible terminals that allow both same-side and opposite-side mounting of incoming and outgoing wires. This design enables quick on-site switching of wiring modes without modifying the overall installation structure, significantly reducing rework time during equipment debugging or system upgrades—ideal for scenarios like frequency converter cabinet retrofits.

• Superior Arc-Extinguishing Performance & Safety:Equipped with a high-performance vacuum interrupter, it delivers strong arc-extinguishing capability, effectively cutting off rated currents and short-circuit currents within the 2.5kV-7.2kV range. There is no arc leakage during operation, and it achieves complete phase-to-phase insulation, minimizing risks of electrical faults (e.g., phase short circuits). It is highly reliable for safety-critical environments such as chemical plants and coal mine power systems.
