A revolutionary concept for the operation of high voltage circuit breakers.
ABB has developed a digitally controlled servomotor system capable of direct driving circuit breaker contacts with high precision and reliability. The number of moving parts in the drive is reduced to just one - the rotating motor shaft.
The Motor DriveTM is applicable for circuit breakers up to 170 kV and type tested in accordance with both IEC and ANSI standards.
Motor Drive has been used in circuit breaker installations all over the world since 2002.
