Arc-suppressing is a totally new concept other than wording of arc-quenching or arc-suffering. The laters are intending to distinguish the electro-arc when it is occurred from power line apparatus. Arc-suppressing on contrary, is to prevent electro-arc occurrence from its source. SEAS-EM3 Smart Electro-Arc Suppressor [SEAS] is the world first design to make the Arc-suppressing come true. By parallel connecting SEAS to every existing AC magnetic contactor, vacuum contactor, power relay and general switches will make them from a serious arcing device to a total arc-free device. SEAS by-pass arcing-circuit before arcing voltage will be formed, a magic performance supported by an advanced, and world patented technologies.
Theory of Operation
By extra high speed detecting / reacting electronic control circuit and a by-pass semiconductor, every single movement of the contactor or switch, will be detected, and instruct by-pass semiconductor to cross over mechanical type contacts of contactor/switch before the contacts open or close, therefore no arcing voltage crossing the mechanical contacts, no arc occurred.
- Much higher overloading capability.
- Require no replacement, no rewiring of existed arcing contactor or switches.
- Reduce power outage time from improving existing magnetic contactor's service life.
- Reduce maintenance cost.
- Additional Benefits on SEAS:
- Arc-less making (close)
- Arc-less breaking (open)
- Power source indication
- Product on service indication
- Self diagnostic function
- Phase loss protection (option)
