The best thermal-magnetic circuit breakers are a significant part of electrical safety. They control the amount of current allowed to flow through a building's electrical wiring.
Suppose the building's electrical system is overloaded. In that case, a circuit breaker detects the problem and shuts down the power supply to protect equipment and wiring until you can restart the electrical system.
However, for a circuit breaker to perform this function well, you need to choose a suitable circuit breaker for your needs.

What Are The Notes When Choosing A Thermal-Magnetic Circuit Breaker?
- Carefully read the information related to the device; you need to find the thermal-magnetic circuit breaker with the size and working capacity to choose the correct one to buy and use effectively.
- It is necessary to choose a type with a solid structure.
- Check the specifications of the circuit breaker before putting it into use.
- The circuit breaker has an anti-counterfeit stamp with the symbol and parameters on the new device body, which is a suitable type.
What Do Circuit Breakers Protect?
Circuit breakers protect power lines from damage caused by large currents. It can be either a short circuit overcurrent or a strong stream of electrons going through the cable for a long enough time, causing it to overheat with further melting of the insulation.
What Is The Function Of A Circuit Breaker?
- Thermal-magnetic circuit breaker performs protection and control functions at the same time.
- Power switching (ability to turn off the protected area in the event of a power failure).
- Reduce the power to the trust circuit when a short circuit current appears.
- Line protection from overload when excessive current flows through the device (this happens when the device's total capacity exceeds the maximum allowed).
