Working Principle
1. Using double-row compound contacts, transverse mechanism, micro-motor pre-storage and micro-electronic control technology, zero arc (no arc extinguishing cover) is basically realized.
2. Adopt reliable mechanical and electrical interlocking technology.
3. Zero-crossing technology.
4. It has obvious on-off position indication and padlock function. It can reliably realize the isolation between power supply and load. It has high reliability and service life of more than 8000 times.
5. Mechatronics design, switch conversion accurate, flexible, reliable, electromagnetic compatibility, strong anti-interference ability, no external interference, high automation procedures.
6. Fully automatic without any external control components.
7.Arc Chute plates to quench arc within the switch and also enhance contact life.
8.Compact body of fiber glass, reinforced polyester resin.
9.Increased thermal withstand capacity of switch body.
