Surge Protection Device | Multi Voltage Rating Three Phase Type 2 SPD For Global Mains Grids

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 specification. Graduated voltage protection levels range ≤1.25kV to ≤2.0kV to suit commercial buildings, factory automation, EV charging stations and laboratories. Full range carries uniform TUV & CE certification for bulk standardized export procurement.

FAQ:

Q1: How to select the matching Uc variant based on site mains voltage?

A: Match Uc to the system maximum continuous operating voltage: 275Vac for nominal 220Vac grids, 385Vac for standard 380Vac industrial systems, 440Vac for sites with wide mains voltage fluctuation.

Q2: Can different Uc modules be mixed inside one distribution cabinet?

A: Mixed installation is not recommended; a single Uc rating must be used per three-phase circuit for balanced surge protection.

Q3: Are base units and accessories interchangeable across the full series?

A: All 4P base frames and mounting hardware are fully universal; only plug-in modules differ by Uc voltage rating.
