Switch Disconnectors (Isolators) provide the means to safely disconnect or isolate an item of electrical equipment from the power supply - primarily designed to provide a means of local isolation when an elecrical item may need maintenance or repair. Switch Disconnectors also i) provide an effective clearance between the supply and the electrical load appropriate to the voltage applied, ii) provide a means of "locking off" (padlocking), iii) provide true indication of contact state, iv) provide a safe electrical disconnection from the power supply even under fault conditions.
