Normal operating voltage range

Open at 65%~120% rated operate voltage; do not open when less than 30% rated operate voltage

Close at 85%~110% rated operate voltage; do not close when less than 30% rated operate voltage

Manual energy storage is operated by the handle allocated with the mechanism, the operating force less than 100 (N.m) Mechanism output angle 40 degrees. CTB spring operating mechanism will be used in ZW32-12 outdoor high voltage vacuum circuit breaker (designed by Beijing Electrical Science Academy) and outdoor or indoor vacuum circuit breaker with equivalent closing power, its performances can meet the requirements of GB1984 AC High Voltage Circuit Breaker and the product's Technical Conditions; CTB-S manual operating mechanism holds functions of manual energy-storage; manual closing/opening; overcurrent protection. CTB-D motor operating mechanism functions include motor or manual energy-storage; electromagnet or manual closing/opening; overcurrent protection. To realize overcurrent protection, the controller holds functions of surge current, time delay, and fast breaking.
