Description
Dual-function combined SPD integrating Type 2 high-current diversion and Type 3 precise voltage clamping, installed at LPZ1-LPZ2 terminal zones and coordinated with front Type 1 arresters for staged surge suppression. 25ns nanosecond phase response instantly blocks grid switching voltage spikes, two Uc variants match regional impulse withstand requirements. Vibration-resistant modular build reduces loose contact risks on production lines, standardized 5N·m torque enables uniform field installation. PA6 V0 flame retardant housing minimizes overheating fire hazards, maintaining stable T2+T3 dual performance from -40℃ up to 80℃ for CNC, lab and medical precision terminal loads.


Product features
● Single module integrates T2 surge diversion & T3 low residual clamping.
● Compatible with full LPZ0B~LPZ2 multi-stage lightning protection chains.
● ≤25ns phase response suppresses microsecond voltage transients.
● Unchanged combined protection performance at 80℃ peak temperature.
● V0 flame retardant housing improves cabinet fire safety rating.

● 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: 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.
