SAD Automatic Change Over Switch

General Information
1. The SAD automatic change over switch is mainly suitable for distribution system or electromotor network of AC 50Hz, rated voltage 380VAC, rated voltage 220VDC, 20~3200A rated thermal current, for switch over between main supply and standby supply, mutual standby supply, or mains supply and generator set load .
2. The switch has 3 poles and 4 poles (3 poles + on and off neutral pole).
3. Current: 20A, 40A, 63A, 80A, 125A, 160A, 200A, 250A, 400A, 630A, 800A, 1000A, 1250A, 1600A, 2000A, 2500A, 3200A.
4. It is suitable for two-way main and standby supply system, self-cast and self-reset.
5. Type
For example: SAD-125/40 125A, 4 poles without bridging bars

Features of SAD Automatic Change Over Switch
1. Adopting double composite contact, horizontal and vertical type framework, micro motor energy pre-storage and micro electronic control techniques, the automatic change over switch can realize “0” arc (No arc cover).
2. The mechanical inter-locking and electrical inter-locking functions ensure effective isolation between power supply and load.
3. Adopting “zero” technique, the automatic change over switch can force to set “0” under emergency situation (isolation off two way power supply at the same time), meeting the requirement of fire protection linkage.
4. The switch change over adopts single electromotor drive for smooth and quiet operation.
5. There is current crossing the operation machine drive motor only at the moment of switch change over, energy saving.
6. Distinct on and off position indicator, padlock function etc.
7. The automatic change over switch offers high automation, high reliability and long life time (8000 times).
8. The use of international advanced logic control technique enables the switch to realize anti-interference performance.
9. The change over switch includes three supply modes: main supply-ON and standby supply-OFF, main supply-OFF and standby supply-ON, as well as main supply-OFF and standby supply-OFF.
10. Four kinds of operation modes: urgent manual operation, electric remote control operation, urgent break-off operation under automatic control state, automatic control operation.
