3P 4P Electric Generator Switch 250A (Automatic Transfer Switch ATS)

3P 4P Electric Generator Switch 250A (Automatic Transfer Switch ATS)

I. Application:

JQ5 ATS used in Generator system, to changeover two power sources. Widely used at the field of important power supply site, which transport, distribution power supply system and automatization system. For fire protection, hospital, bank, building etc, where doesn't allowed power off.

II. Specifications:

Rated current:  100A, 160A, 250A, 400A, 630A, 1000A, 1250A, 1600A, 2000A, 2500A, 3200A

Pole: 3Pole, 4pole

Rated Voltage: 220V, 380V, 440V

Frequency: 50/60Hz

Operation Voltage: 220V-240V

Changeover Time: 0.3S~2.4S

Standard: IEC60947

III. 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
