1. Double row composite contact, side pull mechanism, micromotor pre-storage and microelectronic control technology are adopted to achieve zero flash (no arc extinguishing chamber).
2. Reliable electromechanical interlock, and each component is implemented independently with isolation switch for safe and reliable use.
3. Using over zero technology, the state of emergency can be enforced under the zero(cut down the 2 ways in the meanwhile) to meet the needs of Fire Fighting.
4. The execution load isolation switch is driven by a single motor, and the conversion is reliable, smooth, no noise and small impact.
5. The operator only implements the isolated drive of the electrical load by switching the transient current, and it can work stably without providing current, and the energy saving is significant.
6. Executive load disconnector chain with a mechanical device used to ensure that reliable standby power of non-interference in each other.
7. Obvious off position indicator, padlocks and other functions, high reliability and service life of more than 8000 times.
8. Mechatronics design, switching conversion accurate, flexible, smooth and adopt international advanced logic control technology, anti-interference capability, without external interference.
9. Cooperation with the main power on and standby power off, or the main power off and standby on, the main power and standby power are both off, three kinds stability working.(I-O-II)
10. Easy to install and the control circuit uses direct plug terminal.
11. Four operation modes: emergency manual operation, electric remote control operation,emergency disconnected operation under the automatic state, automatic control operation.
