Our switchboard designs pass full IEC 61439 verification — temperature rise, short-circuit, dielectric and IP tests — at independent laboratories. You receive the verification documents your consultants and insurers ask for.
Each assembly is built on CNC-fabricated frames, wired per approved schematics and routine-tested per IEC 61439 — including wiring verification, dielectric tests and functional checks. Third-party FAT witness (SGS / BV / TÜV) is available.
Main and sub-distribution for commercial complexes, factories, infrastructure, oil & gas and utility projects, from 400A wall-mounted boards to 6300A main switchrooms.
