CT□ Spring Actuating Mechanism

The CT□ type spring operating mechanism is the operating mechanism for vacuum circuit breakers used in 12~40.5KV gas-insulated switchgear. It features a compact structure, attractive appearance, easy installation and adjustment, reliable performance, and is suitable for ZN92 vacuum circuit breakers.

The CT□B type spring actuating mechanism is an improvement on the mature CT19 mechanism, fundamentally resolving reliability issues. It is suitable for operating the ZN85 type vacuum circuit breaker and other types of vacuum circuit breakers with comparable closing power.
