A unique modular design allows for quick and safe service for motors, coils and key components

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 www.abb-drive.com 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
