Circuit Breakers

The IUG666-1-43-20.0-01, otherwise known as a ‘Circuit Breaker’, is a type of electrical switch used to prevent over-currents, which are normally caused by too much load on a system. It uses either a thermal or magnetic mechanism to detect overloads and prevent them from damaging the equipment, allowing the user to simply re-set the breaker and get back to work.

Application Field

Circuit breakers are used in many types of settings, such as in commercial, industrial, and residential applications. These types of applications typically require relays and circuit breakers to provide overcurrent protection. For instance, in industrial applications where personnel safety and equipment protection are key, circuit breakers are often used to protect from short-circuits caused by overloaded components. Similarly, in residential settings, circuit breakers are used to protect from electrical faults caused by overloading on circuits.

Working Principle

The primary function of the IUG666-1-43-20.0-01 circuit breaker is to detect and interrupt overcurrent conditions and prevent them from damaging the equipment. It does this by utilizing either a thermal or magnetic sensing mechanism. In the case of a thermal based breaker, it utilizes a bimetal strip which bends under heat produced by the current overload. This bending action opens a pair of contacts, which interrupts the circuit and shuts it down. In the case of a magnetic type breaker, a flux-shifting element senses the current flow and acts to open the circuit.

No matter which type of circuit breaker is used, they each serve the same purpose of preventing damage to the equipment, allowing the user to simply re-set the breaker and get back to work.

Conclusion

The IUG666-1-43-20.0-01 circuit breaker serves the important purpose of preventing overcurrents and providing protection from short-circuits for a variety of applications. It is available in either a thermal or magnetic design, and works by utilizing a sensing mechanism which opens a pair of contacts and interrupts the circuit when an overload occurs. With this circuit breaker, personnel safety and equipment protection can be ensured.
