Surge Protection Device | Three Phase SPD For EV Charging Station Auxiliary Power Cabinets

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

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.
