In modern power systems, ensuring continuous, safe, and automated operation is becoming a top priority. The Recloser plays a critical role in protecting the distribution network by quickly isolating and restoring power after temporary short-circuit faults.

The NOVA Recloser, manufactured by Eaton’s Cooper (China), is a high-end switching device integrated with advanced technology, optimized for medium-voltage systems requiring high levels of automation, monitoring, and remote operation. The product is officially distributed by My Phuong, a leading company in electrical equipment and SCADA solutions in Vietnam.

Key Features:

NOVAi three-phase automatic recloser, equipped with six integrated voltage sensors and microprocessor-based control (S280-43A).

Advanced solid insulation material; epoxy-molded solid insulator meeting leakage distance and creepage distance requirements, ensuring reliable outdoor operation.
• Vacuum interrupter arc extinguishing chamber.
• Six integrated voltage sensors on both source and load sides.
• Built-in current transformer with 5P20 accuracy class (ratio: 1000:1).
• Permanent magnet actuator with reliable operation capability up to 10,000 switching operations.
• Manual operation function (open/close).
• Intelligent controller with dual-CPU architecture.
• 37-pin control cable.

Practical Applications

The NOVAi recloser is effectively used in various types of projects and systems, including:

• Medium-voltage distribution networks (22 kV, 35 kV, etc.) in urban and rural areas
• Intermediate substations or RMU substations
• Industrial parks, export processing zones, and large manufacturing plants
• Ring-type distribution power systems
• Renewable energy projects (solar power, wind power)
• Ports, airports, and large-scale technical infrastructure

Why choose My Phuong as the supplier of NOVAi Recloser?

My Phuong is not only an authorized equipment supplier but also a comprehensive consulting, implementation, and technical support partner throughout the entire project lifecycle. We have in-depth understanding of Vietnam’s power grid, a highly experienced engineering team, and a commitment to accompanying customers from design, installation to maintenance and operation.

NOVAi Recloser is a next-generation medium-voltage circuit breaker integrated with solid insulation technology, a vacuum interrupter chamber, voltage sensors, and an intelligent control system. The equipment fully complies with international standards and can be easily integrated into modern SCADA–DAS systems. It is an optimal choice for projects requiring high levels of safety, automation, and long-term operational reliability.

 

NOVAs is a modern pole-mounted recloser series integrated with a Disconnect Switch (DS), designed to meet the increasingly demanding requirements of modern medium-voltage power grids—from automation and safety to optimized installation costs.

Manufactured by Eaton’s Cooper (China) and officially distributed by MP Co., the NOVAs recloser is an ideal solution for 24kV ring networks, combining overcurrent protection, load switching, and a three-phase disconnect switch in a compact device, helping to reduce deployment time and ensure safe operation.

Key Features:

• The NOVAs recloser is equipped with solid insulation, eliminating the need for oil or SF₆ gas, thereby reducing the risk of leakage and environmental pollution. At the same time, the vacuum interrupter enables fast switching without arc generation, protecting contacts and extending the equipment lifespan during continuous operation.
• One of the most outstanding features of NOVAs is the integrated three-phase disconnect switch within the device. This eliminates the need for a separate LBS (Load Break Switch), thereby reducing equipment costs, shortening installation time, and ensuring maximum safety for operators during maintenance or isolation from the grid.
• When the overcurrent protection function is disabled, NOVAs can operate as a Load Break Switch (LBS). This feature provides high operational flexibility, especially useful in situations requiring network reconfiguration, load isolation, or maintenance zoning without affecting the entire system.
• The device is equipped with six built-in voltage sensors, enabling accurate measurement on both the incoming and outgoing sides. This is a critical feature for operation in ring networks, supporting power quality analysis, rapid fault detection, and automation of medium-voltage distribution systems.
• The control cabinet accompanying NOVAs supports full communication protocols such as IEC 60870-5-101/104, DNP, and more, ensuring compatibility with SCADA and DAS systems widely used today. As a result, the device enables easy communication, monitoring, and remote control, helping to improve grid management efficiency and support timely fault response.

Practical Applications

The NOVAs pole-mounted recloser is widely applied across various fields:

• 22/24kV medium-voltage distribution networks in urban and rural areas
• Distribution and intermediate substations
• Industrial zones, manufacturing plants, and processing facilities
• Ring network connection and branching points
• Renewable energy projects: solar power and wind power
• Premium residential areas, commercial complexes, and coastal resorts
