The range covers IEC 62271-100 compliant VCBs for primary distribution, load switches for ring main units (RMU) and fuse combinations for transformer protection. Typical applications include power utility substations, industrial plant switchgear, renewable energy interconnection, mining and railway traction supply. XIAOPAI breakers use copper-chrome contact materials and embedded-pole technology, delivering 10,000 mechanical operations and full electrical life up to 30 full short-circuit interruptions. All units carry CE certification, complete type and routine test reports, and export packaging with full documentation for overseas delivery.
