NPS01-FB100 -1000 AC 3+MP Surge Protective Device
Product Overview
Formulated to protect medium-voltage step-up transformer secondary circuits under severe lightning exposure, the NPS01-FB100 -1000 AC 3+MP Surge Protective Device delivers heavy-duty 100kA transient suppression. Combining heavy-duty varistor discs with a high-energy gas discharge tube in a 3+MP configuration, this NPS01-FB100 -1000 AC 3+MP Surge Protective Device prevents phase-to-ground leakage while suppressing destructive overvoltage transients. Our factory manufactures this device to protect solar step-up transformer substations, wind farm collection switchgear, and heavy industrial distribution systems.
Application Scenarios
- Solar Step-Up Stations: 1000V AC secondary windings of transformer stations in utility solar power plants.
- Wind Power Collection: Collector switchboards and transformer distribution panels in onshore and offshore wind farms.
- Heavy Industrial Distribution: High-power motor control centers and mining processing facilities.

Product Advantages
FAQ
Q1: Why is the 3+MP circuit arrangement preferred on 1000V AC distribution?
A1: The 3+MP architecture eliminates continuous earth leakage currents, preventing nuisance RCD/GFCI tripping and enhancing operator safety.
Q2: What is your standard lead time for volume orders?
A2: Standard batch orders ship within 1 to 2 weeks, while custom OEM configurations require 3 to 4 weeks from deposit confirmation.
