Each symbol is designed to represent a specific component in the electrical system. The most common symbol is the rectangle, which typically represents the circuit breaker itself. A triangle usually denotes the breaker''s trip lever, while a circle with an asterisk in the middle is the main shut-off switch.
Here is an example of circuit breaker symbols shown on a basic wiring diagram: The legend indicates that symbols with “GFI” represent GFCI breakers while “SABC” indicates standard circuit breakers. The poles and connections allow tracing the 120V and 240V circuits through the breakers to devices.
Two horizontal lines: the automatic tripping mechanism inside the breaker that causes the contacts to open and stop current flow during an overcurrent condition. This basic symbol tells you that a circuit breaker is present to provide overload protection.
A 2 pole circuit breaker symbol contains two vertical lines representing the two separately controlled poles in a double pole breaker. How do you show a tripped circuit breaker symbol? A slanted versus horizontal contact line indicates the breaker contacts are parted and the circuit is open (tripped). What symbol indicates normally closed contacts?
This represents the key components of a circuit breaker: Two vertical lines: the electrical contacts the breaker uses to connect or disconnect power to the circuit. Two horizontal lines: the automatic tripping mechanism inside the breaker that causes the contacts to open and stop current flow during an overcurrent condition.
These labels provide information about the location of circuit breakers, their ratings, and the circuits they protect. Engineering and Construction Drawings: Electrical engineers and designers use circuit breaker symbols in their drawings and plans for building electrical systems.
They open the circuit when a fault occurs, cutting off power until repairs can be made. Circuit breakers are represented by simple drawing symbols, typically found on electrical plans. These symbols represent a variety of different types of circuit breakers, from those used to isolate circuits to ones designed to protect against line surges.

The so-called energy storage means that when the circuit breaker is de-energized (that is, when it is opened), it opens quickly due to the spring force of the energy storage switch. Of course, the faster the circuit breaker is opened, the better. This is to have enough power to separate the contacts when the segmentation fault has a large current (excessive current will melt the …
