The ABB ADVAC

38 is a medium voltage

circuit breaker tested to the latest IEEE

standards.

ABB’s state-of-the-art medium voltage

circuit breakers use highly automated

manufacturing for the highest quality

assurance. ABB’s millimeter-precision

design reduces maintenance while

helping ensure reliability and safety

for critical applications.

The ADVAC 38 series medium voltage

breakers are characterized by their

compact size, low weight and floor-

rolling withdrawable designs that are

the premium choice for modern electrical

distribution applications.
