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 electric interlock, the executive union parts adopt independency overload disconnect switch, making it more reliable and safe.

3. "Zero" technique, 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 single 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 instantaneous current across, outstanding energy saving.

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

7. Distinct on and off position indicator, padlock function etc. safely realize the isolation between electric power and overload.

8. High security, high automation, high reliability, use life more than 8000 times.
