NPS01-F40-1000 AC 3+MP Surge Protective Device
Product Overview
Tailored specifically for medium-voltage step-up transformer secondary sides in solar power plants, the NPS01-F40-1000 AC 3+MP Surge Protective Device provides coordinated Class II transient overvoltage suppression. Built with high-energy varistors and a heavy-duty gas discharge tube in a 3+MP architecture, this NPS01-F40-1000 AC 3+MP Surge Protective Device diverts 40kA surge currents while eliminating phase-to-ground leakage currents. We manufacture this device to defend utility-scale solar inverter AC collection boxes, step-up substations, and industrial distribution grids operating at elevated AC voltages.
Application Scenarios
- Solar Step-Up Substations: Low-voltage side of 1000V AC solar transformer stations and collection cubicles.
- Utility-Scale Inverters: High-voltage AC output filtering circuits in commercial solar farms.
- Industrial High-Voltage Distribution: Heavy industrial processing plants and specialized mining electrical systems.

Product Advantages
FAQ
Q1: What are the benefits of the 3+MP configuration on 1000V AC systems?
A1: The 3+MP circuit places a gas discharge tube between neutral and protective earth, isolating phase leakage currents and preventing ground-fault tripping.
Q2: What is your standard shipping packaging for export orders?
A2: Units are packaged in moisture-resistant inner cartons, loaded into heavy corrugated master boxes, and secured on fumigated pallets.
