What is application of Load-Switch + Disconnector?
Former Community Member
Load-Switch is using for isolating loads. Disconnector is using for isolating supply. Between loads and supply, there is protection devices (fuses, MCCBs, ...). So we have first 1- supply, then 2- Disconnector, then 3- Protection devices, then 4- Load-Switch and then 5- Loads.
What is application of Load-Switch + Disconnector? then where is protection devices?
A load switch may be an isolator, but it may just be a switch that turns a load on and off- like a light switch does not normally have the ability to be locked off, or a guaranteed contact gap. A disconnector is also a type of switch, but one that is not guaranteed to survive if you try to open it while full current is flowing.
a Load-Switch + Disconnector may just be one device that meets the requirements of all the different classes of device.
Perhaps this article may help explain the differeences.
