Villares Metals is enjoying tangible operational and cost efficiencies at its Sumaré facility after turning to ABB Electrification for a superior, dedicated circuit breaker solution with vacuum actuation technology.
The VD4-AF device delivers 150,000 maintenance-free operations and easily clears furnace-fault currents as high as 31.5 kA, while providing embedded monitoring to ensure safer and more reliable switching protection for EAF operations, along with predictive maintenance.
To operate seamlessly and safely in the harsh arc-furnace conditions, ABB also had to provide a robust solution that could withstand the challenging environment. Its UniGear ZS3.2, a metal-clad air-insulated MV switchgear designed for arduous indoor applications, was commissioned with a customized panel to ensure the highest safety standards in accordance with IEC 62.271-200.
