View Technical Downloads. Since the introduction of the first vacuum interrupter in 1962, Toshiba has been continuously improving and developing its vacuum interrupter technology. Over 185,000 Toshiba vacuum circuit breakers and over 2.7 million Toshiba vacuum interrupters have been installed and are providing reliable service in a wide
A vacuum circuit breaker (VCB) is a type of circuit breaker that uses a vacuum as the arc quenching medium to interrupt the flow of electrical current in a circuit. Vacuum is a superior dielectric and the best medium for arc extinction in circuit breakers. For medium voltage (e.g., up to 38 kV), the vacuum circuit breaker is considered the
This study attempted to establish an optimal design and perform dynamic analysis for a spring-actuated cam-linkage composite mechanism in a rated 12 kV, 25 kA vacuum circuit breaker (VCB). The optimal design of the VCB mechanism involves two steps: the first step involves the optimal design of the stiffness of closing springs and the
The VM1 circuit-break-er is the first vacuum circuit-breaker app-lying a combination of maintenance-free, moulded in vacuum interrupters, mainte-nance-free magnetic actuator and mainte-nance-free electronic controller without auxiliary switches and with sensors. The result is a com-pletely maintenance-free circuit-breaker which functions so
