AISIKAI Automatic Transfer Switch Performance

1. Double complex contact, horizontal and vertical type frame basically, it have come to "Zero" arc(no arc chute);

2. Reliable machine interlock and elecric interlock, the executive union parts adopt independency overload disconnect switch,
it makes more reliable and safety.

3. "zero" techinique, can force to set"zero" under emergency situation(break off two ways power supply at the same time).Meet the requirement of the fire protection linkage.

4. Operate overload disconnect switch change over adopt singless electromotor drive, switch over smooth and reliable, no noise,
little wallop

5. Operate machine drive motor use only under the executive overload disconnect switch change over instanecus current across, outstanding energy saying.

6. Perform overload disconnect switch with mechanism interlock device. It ensure the common use, standby power working
reliable and not interference.

7. Distinct on and off position indicator, padlock function et.c safe realize the isolator between electric power and overload

8. High security, high automatization, high retiablility, use life more than 8000times.
