Description
This 3+NPE three-phase surge arrester is designed for LPZ1-LPZ2 terminal lightning zones with patented GMR ultra-low residual voltage technology to clamp switching and lightning transients quickly. Full L1/L2/L3-N plus independent N-E discharge circuits deliver ≤25ns L-N response time, the 320Vac variant achieves residual voltage as low as 1.0kV to mitigate calibration drift on PLCs, sensors and CNC controllers. Vibration-resistant pluggable modules integrate green/red visual status indicator and NC/NO dry remote contacts, compatible with 2.5~32mm² wide cables. Operating range -40℃ ~ +80℃ suits sealed high-temperature cabinets, fully compliant with GB/T 18802.11-2020 for fine terminal protection of automation, lab and medical equipment.


Product features
● Proprietary GMR technology for ultra-low residual clamping voltage.
● Complete 3+NPE multi-mode phase and earth surge paths.
● Combined T2+T3 staged overvoltage limitation.
● Tool-free single module plug-and-play replacement.
● Stable performance across -40℃ to +80℃ ambient range.

● Suitable for installation in LPZ 1 -2 and subsequent lightning protection zones , it is used as a fine lightning arrester for three-phase power supply systems .

FAQ

Q1: What advantages does low residual voltage bring vs standard SPDs?

A: Ordinary Type 2 SPDs usually deliver residual voltage above 1.3kV; our 320Vac variant reaches ≤1.0kV to minimize transient impact on sensitive measuring hardware.


Q2: Does GMR technology require special wiring layout?

A: Standard 3+NPE three-phase five-wire connection works without custom modifications.


Q3: Why is N-E response slower than L-N channel?

A: Datasheet lists N-E response ≤100ns due to neutral-earth loop impedance characteristics, without compromising overall equipment protection.
