Seminar introducing NOVA circuit breakers by Eaton

On October 08, 2025, My Phuong Trading Co., Ltd. (MPCo) – the official distributor of EATON in Vietnam – successfully organized a seminar introducing EATON’s NOVAs 24kV outdoor pole-mounted medium-voltage circuit breaker solution at VSIP Binh Duong Industrial Park.

The seminar was attended by the leadership and engineering team of MPCo, along with the management, engineers, and grid operation team of VSIP Joint Venture Co., Ltd. The event was not only an opportunity for technical exchange, but also a chance for VSIP engineers to directly experience one of the most advanced switching solutions available today.

About Eaton (USA), a global leader in the design, manufacturing, and supply of safe and efficient energy solutions in the electrical industry, compliant with international standards such as IEC and ANSI. Full-year 2024 revenue reached US$24.9 billion. With more than 100 years of experience and a team of leading experts in the power industry, Eaton is capable of delivering solutions that meet all customer requirements.

During the seminar, My Phuong Company introduced and demonstrated the actual NOVAs 24kV circuit breaker, highlighting its outstanding features and advantages compared to traditional solutions, delivering practical benefits to customers, as follows:

Outstanding features of NOVAs circuit breaker

• Solid epoxy insulation design, vacuum interrupter chamber, type-tested and certified at KEMA (member of the STL international association) in accordance with IEC 62271-100 standards.
• Short-circuit breaking capacity of 20kA/4s, mechanical endurance of 10,000 switching operations.
• Integrated disconnector (DS) with mechanical interlocking for absolute operational safety.
• SCADA/DMS connectivity via IEC 101/104 and GOOSE protocols, supporting selective protection as well as remote monitoring, control, and automation.
• SF₆-free design, environmentally friendly.
• Suitable for installation on main feeders and branch lines using insulated cable networks in 22kV power systems.

Key advantages over traditional switching equipment solutions

• “2-in-1” solution: circuit breaker integrated with disconnector in a single device → reducing the number of poles, conductors, and auxiliary materials.
• Fast and safe installation: reduces installation time by 40–60%, and saves 30–35% of total investment cost compared to separate Recloser + DS solutions.
• Maintenance-free design thanks to a sealed vacuum interrupter structure.
• Flexible operation: can switch between circuit breaker and load break switch (LBS) modes via control panel configuration.
• Compatible with digital grid infrastructure: ready to integrate SCADA/DMS (FLISR) systems for smart grid operation.

Practical benefits for customers

• Reduce investment and operating costs: thanks to intelligent integrated design that optimizes infrastructure and manpower.
• Improve power system reliability: safe operation, reduced connection risks, and equipment lifespan twice that of SF₆ LBS.
• Environmental protection, SF₆-free emissions – towards a green and sustainable power grid.
• Ready for digital grid systems, supporting IEC 104 and GOOSE communications, enabling efficient remote monitoring, control, protection, and automation.
• Technology connectivity – enhancing industrial power infrastructure

During the presentation, VSIP engineers and operation teams were able to directly operate the actual NOVAs equipment, witnessing the differences in structure, durability, and safety of the product.

The NOVAs solution not only demonstrates superior technical performance, but also represents a strategic step by MPCo and Eaton to bring advanced medium-voltage switching technology into smart industrial parks such as VSIP – where performance, safety, and sustainability are always top priorities.
