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 |
