3 Pole Circuit Breaker Symbol - Wiring Draw And Schematic

The three pole circuit breaker symbol is an incredibly important tool for electricians, engineers and other professionals in the electrical field. It’s used to identify a certain type of circuit breaker that has three poles, or switches, instead of the more typical two. This type of circuit breaker is used to provide more protection against overcurrents and short circuits.

Understanding how this symbol works is essential for anyone working with electricity, so let’s take a closer look at what it represents and how it functions.

At its most basic, a three pole circuit breaker symbol consists of three vertical lines and one horizontal line. Each of the three vertical lines is typically labeled as “L1,” “L2” and “L3.” The horizontal line is labeled as “Common.” In addition, each of the vertical lines may have an additional marking on it, such as “Trip Reset” or “Interrupt.”

These markings represent the three different poles of the circuit breaker. The first vertical line, labeled as “L1,” is the line-side, or supply side of the circuit breaker. This is the side of the circuit breaker to which the power is supplied. The second vertical line, labeled as “L2,” is the load-side, or output side of the circuit breaker. This is the side of the circuit breaker from which the power is sent out. Finally, the third vertical line, labeled as “L3,” is the common-side of the circuit breaker. This is the side of the circuit breaker that both the line and load sides are connected to.

Knowing the meanings of these labels is essential for anyone who works with electrical systems as it allows them to properly identify a three pole circuit breaker and understand how it operates. It also gives them the ability to make sure their electrical system is correctly installed and functioning correctly.

It’s important to note that although the three pole circuit breaker symbol is a simple and straightforward symbol, it can be confusing to some people. If you’re unsure of what the three pole circuit breaker symbol means, it’s best to consult with a qualified electrician, engineer or other professional in the electrical field. They can help you understand the nuances of the symbol and ensure that your electrical system is safe and functioning correctly.

All in all, the three pole circuit breaker symbol is an important component of any electrical system, and understanding how it works is essential for anyone who works with electricity. By familiarizing yourself with the symbol and its meaning, you can better ensure that your electrical system is safe and functioning correctly.
