Why we configure
A box doesn’t change anything. A equipment does.

Typical quotation inputs include voltage level, rated current, short-circuit level, transformer capacity, circuit quantity, site environment, drawings and required documents.

Final configuration is confirmed from approved datasheets, single-line diagrams, cabinet arrangement drawings and project standards before production.

Factory-side work can include equipment assembly, secondary wiring, routine inspection, outgoing inspection, packing and document preparation according to the confirmed scope.
