CTB Spring Load Drive Operating Mechanism | Side-Mounted Actuator for ZW32 12kV Vacuum Circuit Breaker

The Model CTB spring operating mechanism is a high-performance drive unit primarily designed for the Model ZW32 pole-mounted vacuum circuit breaker with a rated voltage of 12kV. Its compact and versatile engineering also makes it suitable for a wide range of other indoor and outdoor vacuum circuit breakers and load switches requiring similar closing power. A key feature of the CTB model is its side-mounted configuration, which is specifically designed to significantly decrease the installation depth of switchgear, allowing for more flexible and space-efficient power distribution setups. Built for durability and precision, it ensures reliable switching and protection in demanding grid environments.
