• Introduction to Circuit Breakers

A circuit breaker is a protection device used to prevent overloading of electrical circuits. It is used to regulate the flow of current, preventing damage to circuits and facilities by automatically shutting off the power when an overload is detected. Circuit breakers are designed to switch off quickly in order to prevent a circuit or power system overload or short circuit, thus protecting the system and its components from damage due to excess current. Circuit breakers are used in industrial, commercial, and residential installations, and can also be used as safety switches in hazardous locations.

• 8340-T120-K1M1-ALH0-20A application field and working principle

The 8340-T120-K1M1-ALH0-20A is a thermal-magnetic circuit breaker designed for use in hazardous area applications. It is suitable for use in Class I, Division 1 and Division 2 areas, and it is certified for applications in industries such as oil and gas, petrochemical, and chemical processing. The breaker is designed to automatically switch off the power in case of an overload or short circuit, protecting the system from damage and protecting personnel from electrical shock.

The 8340-T120-K1M1-ALH0-20A circuit breaker works by combining a thermal tripping mechanism, which senses the current load on the circuit, and a magnetic tripping mechanism, which senses the potential for a short circuit. The thermal tripping mechanism is designed to trip when the current load is higher than the breaker’s rated current. The magnetic tripping mechanism is designed to trip when the current rises to a level that indicates an imminent short circuit. The two mechanisms work in concert to provide the best protection possible.

The 8340-T120-K1M1-ALH0-20A circuit breaker is designed to be used in a range of hazardous area applications, including oil and gas, petrochemical, and chemical processing. It offers superior performance, safety, and reliability for these applications, and is certified for use in hazardous Class I, Division 1 and Division 2 areas. The breaker also features an adjustable current setting to provide flexible protection and allow fine-tuning of the breaker’s performance.

• Conclusion

The 8340-T120-K1M1-ALH0-20A circuit breaker is an excellent choice for hazardous area applications. It is designed to provide optimal performance, safety, and reliability in a wide range of applications. The breaker combines a thermal tripping mechanism and a magnetic tripping mechanism for enhanced protection, and its adjustable current setting allows for easy fine-tuning of the breaker’s performance. The 8340-T120-K1M1-ALH0-20A is a reliable, cost-effective choice for hazardous area applications.
