Medium Voltage Metal-Enclosed-VISI-VAC Class 6020

Square D Fuse Selection Tables—HVL

Fuse Selection Tables Boric Acid Fuses—HVL

VISI/VAC® Circuit Interrupters (Not UL Listed)

The VISI/VAC circuit interrupter is a unique device that can be used for the protection of distribution systems rated
2.4 kV through 15 kV. It combines the relayed protective capability of a circuit breaker with visible isolation blades. We have brought this device together with metal-enclosed switchgear in order to create a package that is economical yet provides the fullest range of protection available.
