4410.0662 Circuit Protection

Circuit Breakers

The 4410.0662 Circuit Breaker is a safe, reliable and highly effective electric power device used to protect against electrical short circuits and overloads, protecting equipment and personnel from overload damage caused by these events. The main purpose of this breaker is to act as a critical safety device in the event of an electrical fault. In a nutshell, this breaker helps to protect motors, electrical systems, and other electrical components from overvoltage, overcurrent, and short circuits.

Application Field and Working Principle

The 4410.0662 Circuit Breaker is used in a variety of applications, most notably in industrial low voltage power distribution applications and building applications. This breaker is particularly advantageous in electrical distribution systems because it is able to protect those systems from faults and overloads. The advantages equipment can gain from this protective breaker include the prevention of equipment failure and the prevention of electrical shocks to personnel.

The working principle of the 4410.0662 Circuit Breaker is based on an incredibly sophisticated thermal rotating mechanism. This thermal-sensitive rotating mechanism is a spring-loaded lever that contains a bi-metallic strip. This strip is composed of two different metals with different thermal coefficients of expansion that are welded together. When the temperature surrounding the strip exceeds the pre-defined temperature level, the strip expands more rapidly than the other, leading to the rotation of the lever and an interruption of the circuit.

Once the temperature returns to normal, the bi-metallic strip cools down and returns to its starting position, resulting in the rotation of the lever in the opposite direction and the re-establishment of the circuit. This mechanism allows the breaker to remain off until it is manually reset, preventing the system from becoming overloaded and allowing the breaker to trip without human intervention.

Conclusion

The 4410.0662 Circuit Breaker is a highly effective and reliable device, able to protect against electrical short circuits and overloads. Its thermal-sensitive rotating mechanism is a spring-loaded lever with a bi-metallic strip, capable of interrupting a circuit in the event of an electrical fault. Furthermore, the breaker remains off until manually reset, ensuring the safety of personnel and preventing equipment failure. As such, the 4410.0662 circuit breaker is a great device to consider for industrial low voltage power distribution applications and other similar electrical systems.
