FAQ
Q1: Can T2+T3 combined SPD work without front Type 1 arrester?
A: It serves only as terminal fine protection; full lightning coordination still requires LPZ0B primary Type 1 devices.
Q2: Does the Uoc difference between two Uc models affect selection?
A: 385Vac units feature lower Uoc ≤600V for grids with wider voltage fluctuation.
Q3: What damage occurs from over-tightening terminals beyond 5N·m?
A: Excessive torque deforms cable terminals and damages internal conductive components inside modules.
