ABB UniSafe 2.0

Air Insulated Medium Voltage Switchgear
for Primary Distribution

Certification according to IEC62271-200

UniSafe 2.0 has been type-tested in compliance with international standards and holds a wide range of certifications. The switchgear construction is modular and made up by placing standardized units, side by side in a coordinated way. Safety and reliability are key design criteria, so the units are fully arc-proof. Installation requires very simple civil work.
