Isolation Switch

SG1 SD-Switch Disconnector

SG1 series load-isolation switch is applicable in the circuit of AC 50Hz, rated current 100 A~3150 A (1000 A and above only for electric appliance isolation),rated insulating voltage 800 V and below, rated working voltage 690 V and below. And it is used in the circuits of the distribution or the networks of the motors for non-frequent making , breaking, and isolating.SG1 series isolation switch made in this factory will effectively isolate all loops from live parts and leave an enough space on the contact opening position, with a notable contact on and off status. In addition, it features with the making and breaking capacity,short-time current withstand capacity. SGR1 series fuse combination units load isolation switch has not only all the function above , but also with reliable over-current or shortcircuit safe breaking capacity protection.
