Abstract

Disclosed herein is a device (100, 200) comprising. The device (100, 200) comprises: one or more switching mechanisms (110) configured to disconnect a power supply from a load; and one or more disconnector and earthing switches (330), each disconnector and earthing switch (330) associated with a respective switching mechanism (110). Each disconnector and earthing switch (330) comprising a telescopic disconnector blade (332, 432) having a first end and a second end, wherein the disconnector blade (332, 432) is configured to pivot around the first end between three different positions. The three positions comprise: a first position in which the disconnector and earthing switch (330) is closed and the power supply is connected to the load through the disconnector blade (332, 432); a second, isolation, position in which the disconnector and earthing switch (330) is open and the power supply is disconnected from the load; and a third position in which the power supply is disconnected from the load and a second end of the disconnector blade (332, 432) is electrically connected to an earthing contact (336). Such a disconnector and earthing switch (330) (also termed an earthing disconnection switch) can be termed a 3PS switch (three position disconnector and earthing switch).
