Power circuit breaker

What are power circuit breakers and how do they work?

Circuit breakers are electrical devices that protect circuits from dangerous current loads and short circuits. They are activated when the permissible current is exceeded and instantly interrupt the power supply to the protected circuit. The devices use thermomagnetic or electronic mechanisms that detect current deviations and operate in accordance with established parameters.

These circuit breakers are primarily used in industrial facilities where high currents and intensive loads require durable and reliable protection devices. They are also suitable for protecting large buildings and commercial sites where the safety and reliability of the power supply are of paramount importance.

Types of power circuit breakers

Circuit breakers differ in their characteristics and application, the main types being:

• Automatic air circuit breakers (ACB) - Designed for high current loads and used in harsh industrial conditions.
• Oil-cooled circuit breakers - Suitable for extreme conditions and for protecting high-voltage circuits.
• Electronic circuit breakers - High-tech solutions with the ability to precisely control and monitor current loads.

Choosing a power circuit breaker

When choosing a power circuit breaker, it is important to consider several basic parameters:

1. Rated current: Choose a circuit breaker with a rated current corresponding to the needs of the installation, taking into account the maximum load.
2. Protection type: Different models offer thermomagnetic or electronic protection, with the latter providing more precise control.
3. Breaking capacity: Specifies the maximum current that the circuit breaker can withstand during a short circuit.

Conclusion

Circuit breakers are an important element for protecting electrical installations in industrial and commercial facilities. With the right choice of circuit breaker, long-term security and stability of the network can be ensured. Take responsibility for the protection of your electrical systems and choose the right circuit breakers for the needs of your enterprise.
