Introduction to IUGN1-1-42-5.00 Circuit Breakers

IUGN1-1-42-5.00 circuit breakers are a type of circuit protection device used to protect systems from possible over-current damages. As a mechanical switching device, the IUGN1-1-42-5.00 circuit breaker is primarily constructed from a set of metal contacts, a spring-loaded mechanism and overload releases. This article aims to provide a brief overview of the application fields and working principles of the IUGN1-1-42-5.00 circuit breaker.

Application Field

IUGN1-1-42-5.00 circuit breakers are used in numerous applications and industries. Its applications range from primary over-load protection in electrical systems to providing industrial circuit isolation. Amongst other uses, IUGN1-1-42-5.00 circuit breakers are often found in low power applications, where they are responsible for interrupting the flow of electricity if current overloads occur. Additionally, such circuit breakers can also sometimes be used as a ‘manual transfer switch’ to disconnect loads from their source and to connect them to an alternate source of power supply.

Working Principles

The working of the IUGN1-1-42-5.00 circuit breaker includes three different components, the metal contacts, the spring-loaded mechanism and the overload releases. The metal contacts form the basis of this circuit breaker system, by making or breaking the flow of electricity according to pre-defined current or voltage specs. The spring-loaded mechanism then connects the contacts in a pre-set order when a certain current threshold is reached. The overload releases, in turn, prevent the current from increasing any further.

More specifically, when the current passing meets the breaker’s ‘instantaneous’ trip setting, the surrounding temperature of the breaker will instantly rise. This, in turn, activates the spring-loaded mechanism, causing the breaker’s contacts to be separated. The contacts are then prevented from reconnecting until an operator manually pushes the breaker into the “OFF" position. After the circuit breaker is turned back on, the contacts will close again, allowing electricity to flow through the breaker.

Conclusion

To conclude, IUGN1-1-42-5.00 circuit breakers are a type of circuit protection device that is used for over-load protection and circuit isolation. They mainly use metal contacts, spring-loaded mechanism and overload releases, which together form a safety system that automatically shuts down the flow of electricity when it is overloading. This allows for the protection of equipment from further damage, as well as ensuring the safety of operators.
