The LW8-40.5 outdoor high voltage AC vacuum circuit breaker is a three-phase 50Hz electrical equipment designed for power transmission and distribution systems. This circuit breaker provides reliable control and protection for 40.5kV networks and is suitable for capacitor bank applications.
This product features outstanding breaking performance with a compressed gas interrupter design, delivering long electrical life. Under rated voltage conditions, it can continuously break 40kV short-circuit current 21 times without requiring maintenance. Each unit can be equipped with 2 current transformers for flexible configuration.
The circuit breaker incorporates an advanced MKZ type SF6 pointer density gauge that provides accurate readings unaffected by temperature variations. It comes standard with a CT14 spring mechanism and is available in two structural configurations: floor tank type and porcelain pillar type.
With its robust design and reliable performance, the LW8-40.5 circuit breaker is an ideal solution for industrial power systems requiring high-voltage protection and control capabilities.
