Air Insulated Switchgear Product Value
How can a product add value? By reducing the total cost Or by increasing revenues UniGear ZVC adds value by: Occupying minimum floor space Reduced size of motor cables Higher performance and availability © ABB Group April 19, 2017 | Slide 25 Back to Content

Air Insulated Switchgear Comparisons
Comparison of performance Evaluating UniGear ZVC Fused Vacuum Contactor technology to conventional Circuit Breaker technology for switching applications: UniGear ZVC Fault current limited due to HRC fuses. Fault clearing time is typically <5ms at full fault current. Reduced let through energy allows reduced cable size. Reduced thermal stresses on motor and rapid fault clearing time minimise damage. Up to 1,000,000 op. provides extended service life. Small footprint totalling 0.42 sq m. Circuit Breaker No fault current limiting capability. CB fault break at first natural current zero 200ms. Cable needs to be sized to maximum system short circuit level. Thermal stresses consistent with system short circuit level and clearing time result in severe damage. Up to 30,000 operations service life. Average footprint 1.05 sq m. © ABB Group April 19, 2017 | Slide 26 Back to Content
