Model CTB spring operating mechanism is mainly used in the outdoor Model ZW32-12 pole-mounted vacuum circuit breaker with a rated voltage 12kv and other indoor and outdoor vacuum circuit breaker and load switches with similar closing power. It is used on the side-mounted switchgear to decrease the depth of the switchgear.
Product Overview:
- It features compact, small volume and a longitudinal direct-acting driven arrangement to decrease the size of the switchgear effectively.
- Both manual and motor driven charged operations are available and it is convenience to local or remote operation by the final user.
- The key parts are subjected to the nitrogenation treatment and they are durable and have high impact strength. The component surface adopt composite zinc plating and the long-term low temperature grease is applied so that the product is able to meet different weather conditions.
- Both AC and DC power operation are available and it is convenience for the users without DC power supply.
