A New 5,000-Volt Air-Break Contactor for Industrial Service

This paper describes a line of air-break contactors made for controlling 100-horsepower to 3,000-horsepower motors on 2,400-, 4,160- and 4,800-volt systems. The design features compactness, accessibility, and long life. The arc-rupturing structure has a magnetic blowout and an arc chute which confines and interrupts the arc entirely within its boundaries for all currents which it is rated to interrupt.
