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.
