NPS02-F40 AC 4P Surge Protective Device
Product Overview
Serving as a versatile transient shield for three-phase four-wire industrial power distribution, the NPS02-F40 AC 4P Surge Protective Device delivers robust Class II overvoltage suppression across all active conductors. Featuring four matched high-energy metal oxide varistors with independent dual-spring thermal disconnect mechanisms, this NPS02-F40 AC 4P Surge Protective Device clamps line-to-earth and line-to-neutral transients within 25 nanoseconds. We produce this modular unit to protect main low-voltage switchboards, industrial motor control centers, and data center secondary distribution boards operating on TN-S electrical networks.
Application Scenarios
- Main Low-Voltage Switchboards: Incoming three-phase service panels for commercial buildings, factories, and utility substations.
- Industrial Motor Control Centers (MCC): Pumping stations, compressor rooms, and heavy manufacturing automated drives.
- Data Centers & Infrastructure: Secondary AC distribution boards, centralized UPS input panels, and chiller switchgear.

FAQ
Q1: Under what conditions should I specify the 4P configuration instead of 3+1P?
A1: The 4P configuration is designed specifically for TN-S systems where Neutral and Earth are separate but bonded at the transformer; 3+1P is designed for TT systems.
Q2: What is your standard warranty and technical fault replacement policy?
A2: We offer a 1-year replacement warranty covering manufacturing defects with free 1-to-1 replacements dispatched within 3 business days, backed by lifetime technical support.
