In the contemporary electrical engineering landscape, the NT series (also known as NH fuses) remains the backbone of low-voltage distribution. Our NT00, NT1, and NT2 compatible disconnectors ranging from 100A to 400A are engineered to meet the rigorous demands of global industrial applications. As power systems migrate towards higher efficiency and integration, the role of a reliable disconnector has evolved from a simple isolation switch to a critical safety component that ensures the integrity of the entire electrical grid.
The global demand for NT compatible disconnectors is driven by the rapid expansion of renewable energy systems, data center cooling circuits, and high-intensity manufacturing hubs. In regions like Europe (IEC standards) and Southeast Asia, the NT/NH fuse link system is preferred due to its High Rupturing Capacity (HRC) and excellent thermal stability. OEM manufacturing in this sector is no longer just about mass production; it is about "Precision Protection"—ensuring that a 400A disconnector in a solar farm in Atacama performs with the same reliability as one in a German factory.
Designed to comply with IEC 60269 standards, our NT series ensures seamless compatibility with existing LV distribution boards globally.
Capable of handling short-circuit currents up to 120kA, protecting downstream sensitive electronics from catastrophic failure.
The NT00 (160A), NT1 (250A), and NT2 (400A) sizes allow for a tiered protection strategy in complex switchgear systems.
Located in the Economic Development Zone of Yueqing City, the "Electric Capital of China," IGOYE Energy is a premier OEM/ODM manufacturer specializing in low-voltage electrical solutions. Our 12,000 m² standard workshop is equipped with state-of-the-art production and testing facilities to ensure that every NT disconnector meets the highest safety benchmarks.
With a professional team of 212 employees and 20 technical experts, we adhere to a strict traceability system. From raw material accessories to the final key parameter testing, our SPC tools guarantee process control excellence.
The future of 100A-400A disconnectors is intrinsically linked to the Industry 4.0 and Smart Grid transitions. Our R&D department is currently focusing on three key technical trajectories:
| Technological Pillar | Focus Area | Outcome |
|---|---|---|
| Material Science | Silver-plated Copper & Ceramic Reinforcement | 30% reduction in contact resistance and improved heat dissipation. |
| Smart Monitoring | IoT-Integrated State Sensors | Real-time thermal monitoring to prevent accidental arching or melting. |
| Sustainability | Eco-friendly Thermoplastics | Full compliance with EU ROHS and circular economy recycling protocols. |
Our NT00/NT1/NT2 disconnectors are not "one size fits all." We customize solutions based on localized environmental factors:
Gongneng Electric provides intelligent plastic shell motor protection, ensuring stable pump operation even during frequent starts. NT series disconnectors act as the secondary protection layer for heavy-duty filtration units.
Operating in harsh environments, our high-reliability distribution systems ensure power supply continuity for refining enterprises where downtime equals massive financial loss.
Supporting food, textile, and printing sectors with intelligent circuit breakers that enable real-time monitoring via PC and mobile terminals, enhancing energy management efficiency.
