ANSI indoor vacuum circuit breaker ADVAC

The ADVAC series is a complete line of ANSI-rated vacuum circuit breakers with a spring-charged mechanism offering power distribution system customers the advantages of the latest technology with a modular design that is easily maintainable.

Key benefits 

• ABB EL spring mechanism used on various ANSI and IEC breakers to provide up to 20,000 mechanical operations in a compact, modular design that is readily accessible and easily maintained to reduce downtime
• Modular Smart Coil assembly used in multiple ABB breakers provides close, open and undervoltage actuation in one simple assembly
• The motor assembly can be replaced by removing a single screw, thereby reducing downtime
• Vacuum interrupters completely embedded in a solid insulation material provide superior protection against dust, dirt and condensation, and are less susceptible to failure due to contamination, tracking or partial discharge

Key features 

• 5kV, 8kV, 15 kV, and 38kV heavy duty breaker rated at 1200A, 2000A, 3000A and 4000A FAC continuous current and 25 kA thru 63 kA interrupting current
• Safety features include standard built-in mechanical anti-pumping device, KIRK key, padlocking, push-button cover provisions and closed-door racking
• The racking mechanism (truck) is integrated into the breaker and designed to 180 ft²lb torque rating to provide increased reliability and reduced maintenance costs
