A Truly Powerful 80kA Surge Protector, Built to Handle "Thunder and Lightning"

Heavy-Duty Capacity with Extra Safety Margin

With a maximum discharge current of 80kA, this model far exceeds the common 40kA standard. While standard SPD 40kA devices suit light commercial applications, this 80kA version delivers double the capacity for high-risk environments like petrochemical plants and wind farms—meaning longer service life and greater resilience when it matters most.

Built for Tough Industrial Environments

Designed specifically for single-phase TN systems, the 80kA surge protector delivers dependable protection for DCS systems and sensitive equipment, whether in oil drilling platforms with unstable power grids or remote wind turbine towers where maintenance access is limited.

Hot-Pluggable Design for Zero-Downtime Maintenance

Faulty modules can be replaced without powering down—no need to schedule outages. A single worker can complete the replacement in just 10 seconds, and the intuitive status indicator makes inspections effortless, reducing long-term maintenance costs by up to 60%.
