Circuit Breakers

A Circuit Breaker is a device designed to protect an electrical system against short circuit faults and overloading. Circuit breakers are used in a wide range of applications, from home appliances to industrial electrical systems. The 229-2-39307-20 is one example of a circuit breaker that is commonly used in a variety of applications.

Application Field

The 229-2-39307-20 circuit breaker is commonly used in motor installations and air-conditioning. It also is often applied to water and heating systems. The circuit breaker has a wide voltage and current range, allowing it to be used in both residential and commercial appliances. Furthermore, this type of circuit breaker is suitable for use in as many as five separate electric systems, such as lighting, fan, and air-conditioning systems.

Working Principle

The 229-2-39307-20 circuit breaker works by utilizing the bi-metal element. When the current through the bi-metal element increases, the bi-metal element bends due to the temperature effect caused by the increased current. This in turn trigg ers the lever on the circuit breaker arm to close the contact and cut off the current. In addition, Circuit Breaker contains an Overload Curve which allows it to trip faster than one without, thus providing the required protection.

When the current drops, the circuit breaker contacts open, cutting off the supply to the equipment. This allows the system to reset itself and prevents further damage from occurring. In addition, the circuit breaker also has a safety mechanism called an arc extinguish chamber. This mechanism is designed to dissipate the arc in the contact points caused by a sustained overload. The arc extinguish chamber consists of quenching materials which absorb heat from the arc and reduce the current.

To increase the 229-2-39307-20 circuit breaker\'s reliability, the device is also designed to be resistant to vibrations and impacts. This makes the circuit breaker suitable for high-traffic or hostile environments. Additionally, the circuit breaker is designed to operate properly even when the current flows in the opposite direction. This prevents excessive wear and tear on the contact points when the current keeps flowing in the opposite direction.

Conclusion

The 229-2-39307-20 circuit breaker is designed to provide reliable protection for electrical systems. It utilizes a bi-metal element to trip and reset the circuit breaker when the current exceeds a certain threshold. Additionally, the circuit breaker contains an Overload Curve and an arc extinguish chamber to dissipate arcs in the contact points caused by sustained overloads. Furthermore, the circuit breaker is designed to be resistant to vibrations and impacts, making it suitable for use in high-traffic or hazardous environments.
