Non-Fused Switch Disconnectors

Non-fused Switch Disconnectors are an electrical safety device designed to power down and isolate a part of an electrical circuit prior to it being serviced or maintained.  Non-fused switch disconnectors use a knife-blade or rotary disconnect to break a circuit as opposed to fused versions, meaning they can be reset easily without the need to replace a fuse.  Rotary non-fused switch disconnectors open the circuit by rotation of a lever, while knife-blade switch disconnectors use a hinge to lift a lever off its slot and break the circuit.

A non-fused switch disconnectors primary function is as a safety measure and they are intended for isolation purposes only within an electrical circuit. Non-fused switch disconnectors come in a variety of differing types and styles to suit numerous electrical circuits and applications, they can have different power handling capabilities, voltage ratings, as well as differing maximum current capabilities. All of these attributes will have to be considered to ensure your choice of non-fused switch disconnector is the correct one for your particular circuit isolation application.
