IUL1-28520-2

Circuit breakers are widely used in modern electrical systems to control the flow of electricity. The purpose of circuit breakers is to prevent overcurrents, overvoltages, and short circuits from damaging electrical equipment. One type of circuit breaker is the IUL1-28520-2. This circuit breaker is designed to provide overload protection, as well as short circuit protection. Its application field and working principle are discussed in this article.

The IUL1-28520-2 circuit breaker is used in alternating current (AC) circuits up to 415V. It is rated for 25, 32 and 40A, so it is suited for circuits with higher current requirements. The IUL1-28520-2 can be used in both residential and industrial applications. It is often used in switchgear and electrical control panels. It is designed to provide overload protection as well as short circuit protection. 

The working principle of the IUL1-28520-2 circuit breaker is based on the thermal-magnetic principle. It is equipped with a thermostat which senses current flow and sends a signal to the circuit breaker when it exceeds the preset limit. The current then passes through the magnetic element, which acts as a switch that opens or closes the circuit. 

The IUL1-28520-2 also has an adjustable short circuit release, which causes the circuit to trip if the current exceeds the preset limit. It also has adjustable current limiting and overvoltage release settings. The current settings can be adjusted by using a screwdriver to move the adjustment screws. The overvoltage release setting can also be adjusted, if necessary. 

In summary, the IUL1-28520-2 circuit breaker is used in alternating current circuits to provide overload protection and short circuit protection. It is equipped with a thermostat which senses current flow and opens or closes the circuit when necessary. The IUL1-28520-2 also has adjustable current limiting and overvoltage release settings. It is suitable for residential and industrial applications and is rated for 25, 32 and 40A.
