Distribution Surge arrester
Eaton’s Cooper Distribution Surge Arrester – Gapless type, voltage 3-48kV, nominal discharge current 10kA, IEC 60099-4 compliant, type tested at DEKRA lab (STL).
In medium-voltage power systems, selecting the right distribution surge arresters is a key factor in ensuring the continuity and safety of the entire network. Moving beyond a simple protective role, modern devices must now simultaneously meet multiple international standards and operate stably under harsh weather and environmental conditions.

Impressive Technical Specifications of Distribution Surge Arresters
Key Features:
- Gapless technology completely eliminates air gaps, enhancing dielectric strength and reducing the risk of breakdown during high-voltage faults. As a result, the device remains in a constant state of readiness, providing instantaneous system protection. This is an ideal solution for environments with high lightning frequency or continuously operating systems.
- With a nominal discharge current of 10kA, the product is fully capable of handling strong surge impulses commonly encountered in medium-voltage distribution systems. The Class 1 / DH discharge class indicates that the device meets stringent protection standards, particularly in areas at risk of direct or indirect lightning strikes. The equipment operates stably, ensuring the safety of transformers and terminal devices.
- The product complies with IEC 60099-4, a prestigious international standard for surge arresters. Additionally, the device has passed type tests at DEKRA lab, an official member of the STL (Short-Circuit Testing Liaison), affirming its quality and reliability under all operating conditions.
Practical Applications
Distribution surge arresters are effectively utilized in various medium-voltage electrical systems, particularly in:
- Medium-voltage substations
- Industrial zone distribution systems
- High-rise buildings and commercial centers.
- Airports, seaports
- Renewable energy systems (solar farms, wind farms)
- Overhead medium-voltage lines and inter-station connections
With its compact design, high performance, and proven reliability, the product is easy to install and integrate into any modern electrical system.
