Sanhe SEK Series Mono-stable Permanent Magnet Actuated Vacuum Contactor, as a new generation of high voltage vacuum contactor, is fitted a permanent magnet mechanism to close/open the dynamic and static contacts of the vacuum interrupter in a direct motion. SEK Series Mono-stable Permanent Magnet Actuated Vacuum Contactor is applicable in the three-phase AC system (Voltage: 12kV and below; Rated Frequency: 50Hz/60Hz) that requires frequent switching operations. SEK Series Mono-stable Permanent Magnet Actuated Vacuum Contactor adopts an efficient and reliable electronic control module with a wide voltage range, which is responsive during switching operation and has auxiliary contact output capability.
It is widely used to control and protect the power distribution systems in power, machinery, metallurgy, mining, petroleum, chemical, railroad, broadcasting, communication, transportation, and other fields.
Features
maintenance free
reliable vacuum interrupter technology
frequent operation support
Mono-stable permanent magnet actuator
long electrical and mechanical life
wide voltage power supply module
small closure value
compact structure
