1. Appearance design: Compact and integrated, easy to install
The DASN series three-phase current transformers launched by Wenzhou Heyi Electric Co., Ltd. have the primary advantage in their innovative appearance and structural design. This series inherits from the mature DAS series and has undergone targeted structural optimization.
1.1 Integrated structure, high space utilization rate
The product adopts a three in one integrated structure designed specifically to match mainstream molded case circuit breakers (MCCBs). The center distance and installation dimensions of the window strictly follow the CM1 and other circuit breaker frames, achieving seamless installation inside the distribution cabinet. This highly integrated design fundamentally solves the problem of loose layout and large space occupation of traditional split type transformers, and is a direct manifestation of the concept of efficient integration.

1.2 Humanized details for more convenient operation and maintenance
The series of products can be equipped with transparent terminal covers for easy on-site observation of wiring status, while also providing protection against dust, moisture, and corrosion. The overall design is compact and lightweight, greatly simplifying the handling and assembly process, significantly saving installation time and labor costs, and once again verifying the value of efficient integration from the user end.
2.Performance parameters: stable and accurate, safe and reliable
The DASN series not only pursues integration in structure, but also achieves a high standard and high reliability in core electrical performance, ensuring stable operation in various harsh environments.
2.1 Broad electrical adaptability
The product is suitable for AC circuits with a rated voltage of AC 0.72kV and below and a frequency of 50/60Hz. The primary current covers a wide range of 60A to 1600A, and the secondary output provides 5A or 1A options, which can flexibly adapt to the needs of different measurement and protection equipment. This wide range of adaptability is the foundation for it as an efficient integrated solution.

2.2 Excellent environmental tolerance and safety standards
The product has strong overload capacity (1.2In), high-level thermal stability current (60In), and dynamic stability current (2.5Ith). The working temperature range is wide up to -10 ℃~50 ℃, and the flame retardant level reaches V0 level, ensuring safe operation under complex working conditions. Its accuracy meets the FS5 limit coefficient requirements and has passed multiple international and domestic authoritative certifications such as IEC60044-1 and GB1208-2006, providing a solid guarantee for the efficient integration and long-term stable operation of the system.
3.Application scenarios and core values
The birth of the DASN series stems from a profound understanding of market demand, and its design always revolves around creating greater value for users.
3.1 Wide application coverage
This series is an ideal matching device for molded case circuit breakers, widely used in low-voltage distribution systems, smart meters, energy management systems, industrial automation control, and commercial building power distribution. Whether it is a new project or a renovation project, its ready to use feature can achieve rapid deployment and upgrade of the system.
3.2 Creating Systematic Value
Choosing the DASN series means that users not only receive a single component, but also an optimized system solution. It helps customers achieve comprehensive and efficient integration of power distribution systems in terms of space, efficiency, and reliability by saving valuable cabinet space, simplifying wiring complexity, improving overall system aesthetics, and reducing overall installation costs.
4. Conclusion
In summary, the DASN series current transformers, with their iconic compact structure, robust and excellent performance parameters, and scenario oriented application design, perfectly embody the development direction of efficient integration of modern electrical equipment. Wenzhou Heyi Electric Co., Ltd. will continue to deepen its cultivation of transformer technology, drive development with innovation, and provide more intelligent, reliable, and valuable power measurement solutions for global partners.
