NPS02-F40 AC 1+1P Surge Protective Device
Product Overview
Manufactured on our automated assembly lines for single-phase low-voltage electrical distribution, the NPS02-F40 AC 1+1P Surge Protective Device provides dependable Class II overvoltage protection in a 1P+NPE configuration. Built with an MOV between Phase and Neutral and a heavy-duty gas discharge tube between Neutral and Earth, this NPS02-F40 AC 1+1P Surge Protective Device eliminates phase-to-ground leakage while safely diverting 40kA surges. Our factory engineered this modular device specifically for single-phase TT and TN-S residential consumer units, commercial lighting panels, and telecom AC power distribution boxes.
Application Scenarios
- Residential & Light Commercial: Single-phase consumer consumer units, main incoming distribution boxes, and tenant panels.
- Telecom Power Distribution: AC input distribution units (PDU) for cellular base stations and remote relay sites.
- Commercial Building Automation: Security system power panels, fire alarm control cabinets, and HVAC control boards.

Product Advantages
FAQ
Q1: Why is the 1+1P (1P+NPE) configuration recommended for TT grounding networks?
A1: The spark gap between Neutral and Earth prevents leakage current to ground, eliminating nuisance tripping of upstream RCDs in TT networks.
Q2: Can I mix different Uc voltage ratings within a single 100-set MOQ order?
A2: Yes, we allow mixed voltage ratings within one order to help distributors meet varied local market requirements.
