NPS01-FB150 -760 AC 3P Surge Protective Device
Product Overview
Representing the highest surge current capacity in our commercial AC portfolio, the NPS01-FB150 -760 AC 3P Surge Protective Device delivers an outstanding 150kA maximum discharge rating for 690V/800V AC networks. Utilizing heavy-duty varistor discs and our patented diagonal internal architecture, this NPS01-FB150 -760 AC 3P Surge Protective Device expands current-carrying capacity by 50% while holding clamping residual voltages remarkably low. Our factory manufactures this heavy-duty unit to serve as the primary protective shield for exposed wind turbine switchboards, utility solar inverter transformer skids, and heavy industrial distribution switchgear subject to severe direct and induced lightning strikes.
Application Scenarios
- Wind Power Plants: Main nacelle electrical panels, tower base incoming switchgear, and wind farm collection substations.
- Solar Central Inverter Substations: Primary 690V/800V AC distribution skids in utility-scale solar installations.
- High-Exposure Industrial Sites: Coastal crane power feeds, mining primary distribution, and heavy metallurgical switchgear.

Product Advantages
FAQ
Q1: Why is a 150kA Imax rating recommended for wind turbine installations?
A1: Wind turbines are highly exposed structures vulnerable to direct lightning; the 150kA rating ensures reliable energy absorption and prevents premature device failure.
Q2: What warranty and after-sales support do you provide for large utility projects?
A2: We offer a comprehensive 1-year replacement warranty with free one-to-one replacements within 3 business days for any manufacturing defects, followed by lifetime cost-price service.
