Product Description
Three-phase auxiliary distribution cabinets inside EV charging stations are vulnerable to lightning induced surges and grid switching impulses, which cause charger mainboard and metering module breakdowns and downtime. This 4-pole Type 2 SPD is mounted in LPZ0B-LPZ1 secondary panels within charging stations, diverting lightning transient currents with 40kA surge capacity and clamping residual voltage within safe limits via ≤25ns fast response to protect charger control and metering hardware. Wide-temperature construction withstands temperature swings in indoor charging station rooms adjacent to outdoor chargers; remote signalling contacts send fault alerts to charger cloud monitoring systems, and pluggable modules simplify station maintenance replacement. TUV & CE certification meets compliance standards for overseas EV charging projects.
Key Features
4-pole full-phase protection matches three-phase AC charger auxiliary power circuits
-40℃~+70℃ tolerance fits fluctuating temperatures inside charging station electrical rooms
Remote signalling contacts integrate with charger cloud back-end monitoring
40kA surge capacity handles frequent induced lightning transients during thunderstorms
TUV & CE certified for international EV charging station export engineering
FAQ:
Q1: Is extra Type 3 SPD required for outdoor charging gun terminals?
A: This Type 2 unit protects station main panels; supplementary Type 3 fine protection at charging gun terminals delivers coordinated multi-stage surge safety.
Q2: Can multiple EV chargers share one single 4P SPD?
A: One SPD covers the cabinet three-phase main incoming line; no duplicate main SPDs are required for branch charger circuits inside the panel.
Q3: Does performance remain stable in charging station electrical rooms during hot summer periods?
A: Rated maximum operating temperature 70℃ supports continuous long-term protection with adequate cabinet ventilation.
