CT-VS1-MOP Spring Operating Mechanism
CT-VS1-MOP spring motor drive operating mechanism, modular design, independence mounting, will be used in VS1-12kV, VS1-24kV, ZN85-36kV
and indoor medium voltage vacuum circuit breaker with equivalent closing power. Its performances can meet requirements of IEC62271-100,
GB1984 AC Medium Voltage Circuit Breaker and the product's Technical Conditions.
CT-VS1-MOP were 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.
