What are the most common circuit symbols?
Here is an overview of the most used symbols in circuit diagrams.Battery.
The symbol for a battery is shown below.
Variable resistor (Potentiometer) The variable resistor or potentiometer is drawn in several different ways.
What is the symbol of circuit breaker?
1200 A Identifies the drawout circuit breaker represented by the symbol as a 1200 ampere circuit breaker. 225 A/3P Indicates the fixed circuit breaker represented by the symbol as a 225 ampere, three-pole breaker.
What is the symbol of fuse?
It is the symbol for fuse switch disconnector. It is a fuse in series with a switch. It can switch the device manually and also provide the protection against overcurrent by breaking the circuit. These both symbols represent a protection resistor.

What do the numbers mean on a circuit breaker?
Each circuit in your home has a corresponding breaker. … They can handle 120 volts and are either 15 amps or 20 amps. (See the numbers on top of the switches?) Double pole – These look like two switches joined together. They can handle 240 volts and are usually between 15-125 amps.
What is ACB and VCB?
ACB Stands for Air Circuit Breaker where as VCB stands for Vaccum Circuit Breaker. ACB is used for the voltage level upto 440V, whereas VCB is used beyond the 440V. Both circuit breakers differ from each other only in terms of arc quenching medium they are using.
What is circuit breaker with diagram?
A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current from an overload or short circuit. Its basic function is to interrupt current flow after a fault is detected.
What do circuit symbols mean?
An electronic symbol is a pictogram used to represent various electrical and electronic devices or functions, such as wires, batteries, resistors, and transistors, in a schematic diagram of an electrical or electronic circuit.
