RW11-12KV High Voltage Current Fuse, 12.5KA-50KA Breaking Capacity for Power Systems
Product Spotlights
As a professional manufacturer with over a decade of experience in electrical protection, Jinhua Dika Electrical Equipment Co., Ltd. proudly presents the RW11-12KV High Voltage Current Fuse. Engineered for robust performance in demanding power systems, this fuse is a critical component for safeguarding transformers, capacitor banks, and feeder lines against overcurrents and short circuits. Our commitment to quality, backed by a comprehensive management system including ISO9001 and ISO14000, ensures every unit delivers reliable protection, contributing to the stability and safety of electrical networks worldwide.
The RW11-12KV fuse is designed to interrupt fault currents swiftly and safely, preventing extensive damage to expensive equipment and minimizing downtime. Its high breaking capacity, ranging from 12.5KA to 50KA, makes it suitable for a wide array of applications within utility and industrial power systems. We understand that system reliability is paramount, which is why our fuses are manufactured with precision and undergo rigorous testing to meet the exacting standards required for high-voltage protection.
Core Features and Technical Advantages:
- High Breaking Capacity: With an interrupting rating from 12.5KA to 50KA, it can reliably clear severe short-circuit faults, protecting downstream equipment.
- Precise Overcurrent Protection: The fuse element is carefully calibrated to provide accurate time-current characteristics, ensuring selective coordination with other protective devices.
- Drop-out Design (Typical for RW11): Upon operation, the fuse link drops out, providing a visible open gap for easy identification of a blown fuse and enhancing operational safety.
- Durable Construction: Built with high-quality materials to withstand environmental stressors such as UV radiation, moisture, and temperature fluctuations common in outdoor substations.
- Easy Installation and Maintenance: Designed for compatibility with standard fuse cutouts, allowing for straightforward installation and replacement, reducing maintenance time and costs.
- Customizable Ratings: Available in various current ratings to match specific system requirements, ensuring optimal protection for different load conditions.

- Improved Safety: The drop-out action provides a clear visual indication and a physical isolation point, enhancing safety for maintenance personnel.
- Simplified Coordination: Well-defined time-current curves facilitate easier coordination with reclosers and other fuses, improving overall system selectivity.
- Reduced Downtime: Fast fault clearance and easy replacement mean shorter outage times and quicker restoration of service.
Frequently Asked Questions (FAQ)
-
Q: What is the primary application of the RW11-12KV fuse?
A: It is primarily used for overcurrent and short-circuit protection of transformers, distribution feeders, and capacitor banks in 12KV power systems. -
Q: How do I select the appropriate breaking capacity (KA rating)?
A: The selection depends on the prospective short-circuit current at the installation point. You need to choose a fuse with a breaking capacity higher than the maximum calculated fault current in your system. -
Q: Is this fuse suitable for indoor use?
A: The RW11 series is typically designed for outdoor applications on poles or in substations. For indoor switchgear, other fuse types might be more appropriate. -
Q: What is the meaning of the "drop-out" feature?
A: When the fuse element melts due to an overcurrent, the fuse tube is released and pivots downward, creating a visible open gap. This clearly indicates a operated fuse and provides additional isolation. -
Q: Can I get fuses with specific current ratings?
A: Yes. We offer customizable current ratings to match your specific load requirements. Please provide your needed amperage during inquiry. -
Q: What certifications do your fuses hold?
A: Our manufacturing processes are certified under ISO9001 for quality management and ISO14000 for environmental management. Specific product certifications can be provided upon request based on destination market requirements. -
Q: What is the typical delivery time for an order?
A: Lead time depends on order quantity and customization. Standard models typically have shorter lead times. We ship globally from major ports like Shanghai, Tianjin, Guangzhou, and Ningbo. -
Q: Do you provide technical support for fuse selection and coordination studies?
A: Yes, our technical team can provide guidance on product selection and application based on your system parameters. Support is available upon request.
