CTB Spring Operating Mechanism
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 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 including 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.
