surge protection device

Product Description Laboratory precision measuring instruments are highly sensitive to voltage fluctuations and lightning surges; transient high voltage causes sensor calibration drift and permanent circuit damage. This 4-pole Type 2 SPD is installed on lab three-phase incoming distribution panels. The low voltage variant delivers residual voltage as low as ≤ 1.25kV with ≤ 25ns nanosecond-level response to divert surge currents and contain impulse voltage within instrument

About this item ● High Surge Protection:Nominal discharge current 20kA, max. 40kA (8/20μs), residual voltage ≤1.25kV, effectively protects against lightning and overvoltage. ● Safe & Durable:Modular pluggable design with anti-vibration, V0 flame-retardant shell and built-in temperature release for long service life. ● Easy to Use:Standard 35mm DIN rail mounting, supports 2.5-25mm² wiring, with visual status window and remote signaling for convenient monitoring.

Product Description Three-phase mains continuous operating voltage varies across global regions, making single-rating SPDs incompatible with all international distribution projects. This series 4-pole Type 2 surge arrester offers four Uc voltage options covering mainstream 275~440Vac three-phase grid standards, with consistent form factor, mechanical structure, surge capacity and monitoring functions across all variants to simplify standardized panel design and project

Product Description Conventional SPDs suffer false tripping and performance degradation in cold workshops or sealed high-temperature cabinets. This 4-pole Type 2 surge arrester maintains consistent performance from -40 ℃ to +70 ℃ , equipped with dedicated low-temperature thermal release to avoid unnecessary disconnection under extreme cold. 40kA surge capacity and ≤ 25ns response time remain consistent regardless of ambient temperature shifts, with stable residual voltage

Product Description Integrated non-detachable SPDs require full removal and complete rewiring upon failure, increasing maintenance time and loose wiring risks. This SPD adopts split base + independent pluggable module structure: when one module degrades, only the faulty unit needs extraction and replacement with all base, phase and PE wiring untouched to cut on-site wiring labor. Anti-loose locking buckles resist long-term cabinet vibration, while each single module

Product Description Industrial-grade Type 2 SPD fits 385Vac three-phase factory distribution cabinets for LPZ0B-LPZ1 zones, delivering surge protection for factory automation, EV charger auxiliary power and lab precision instruments. It carries 20kA nominal discharge current and 40kA maximum surge capacity with ≤ 25ns response time to clamp transient high voltage instantly. Pluggable modules simplify maintenance replacement, anti-vibration construction withstands production
