1. Adopt dual composite contacts, embedded mechanism, micro-motor pre-energy storage and micro-electronic control technology, basically achieving zero arcing (no arc extinguishing cover).
2. Adopt reliable mechanical interlock and electrical interlock; the executive component adopts an independent load isolation switch, ensuring safe and reliable use.
3. Adopt zero-crossing technology; in case of emergency, it can be forced to zero position (cut off both power sources at the same time) to meet the needs of fire linkage.
4. The switching of the executive load isolation switch is driven by a single motor, featuring reliable and stable switching, no noise and small impact force.
5. The drive motor of the operator only passes current at the moment of switching the executive load isolation switch; no working current is required when there is no switching, achieving significant energy saving.
6. The executive load isolation switch is equipped with a mechanical interlock device to ensure that the common and standby power sources work reliably without mutual interference.
7. It has obvious on-off position indication, padlock and other functions, reliably realizing isolation between power supply and load.
8. It has good safety performance, high automation and high reliability.
9. The product has a zero position state.
10. Easy to install; the control circuit adopts plug-in terminal connection.
11. Operation functions: manual operation and automatic control operation. Manual operation is prohibited in automatic state; if manual operation is required, the automatic electrical lock position must be turned off.
