Electrical standard symbols
Fuse Switch This symbol represents a fused switch. A fuse switch performs the action of switching by physically removing the fuse because the fuse is the part of the switch. Isolator Switch Disconnector It is a also known as disconnector switch or isolator switch is used for isolating and completely de-energizing the circuit.

1. Graphic symbols of substation elements Substations are usually presented using various elements (e.g. power transformers, circuit breakers, isolators, instrument transformers CTs, VTs etc.) by their graphic symbols in the connection schemes. Symbols of the most important equipment in transformer substation are given below.
Electrical Warning Labels & Labelling
An opto-isolator (also called an optocoupler, photocoupler, or optical isolator) is an electronic component that transfers electrical signals between two isolated circuits by using light. [1] Opto-isolators prevent high voltages from affecting the system receiving the signal. [2]

Warning Sign Isolator
The isolator can be defined as; it is one type of mechanical switch used to isolate a fraction of the electrical circuit when it is required. Isolator switches are used for opening an electrical circuit in the no-load condition. It is not proposed to be opened while current flows through the line.

What is the electrical symbol for an isolator? The symbol used to represent an isolator in an electrical circuit will depend on what type of isolator it is. We have listed below some of the most common types and the symbols that represent them. Single phase circuit breaker 2 phase circuit breaker 3 phase circuit breaker
