The IE-CD-12 high-voltage circuit breaker is equipped with a spring actuator designed for operation with 12 kV AC rated metal-enclosed switches. The actuator uses flat helical springs to store energy and control the operation of the load disconnect switch, while compression springs are used for grounding operations. The device operates in three positions: closing, opening, and earthing.
This product features a five-step locking function, is compact in size, easy to install, and highly adaptable. It has undergone comprehensive testing and complies with the standards outlined in GB3804-2004 "3.6KV-40.5KV AC Load Switches," GB3906-2006 "3.6-40.5KV AC Metal-enclosed Switchgear and Controlgear," and GB16926-2009 "AC Load Switches - Devices Combined with Fuses."
