ABB ADVAC Indoor Vacuum Circuit Breaker

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.

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.

Features

5 to 15 kV heavy duty breaker rated at 1200 A to 3000 A continuous current and 25 kA to 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

Remote motorized racking options are available.
