Circuit breakers are important components in maintaining the safety and reliability of electrical circuits. The IUGZX2-35599-20 is a type of circuit breaker, and its application field and working principle are discussed below.

IUGZX2-35599-20 Application Field

The IUGZX2-35599-20 circuit breaker is applicable to household circuits, small-sized motor circuits, and non-frequent start/stop equipment and lighting circuits. It is most suitable for protecting overload and short-circuit in 50Hz, single phase AC circuits with rated voltage of 230V and rated current of 6-25A. It is also worth noting that the IUGZX2-35599-20 is not recommended for use in circuits with a residual alternating current (AC) of more than 0.1mA.

Working Principle

The IUGZX2-35599-20 works on the basis of thermal-magnetic tripping. Thermal-magnetic trips use both electrical and thermal feedback components to respond to over-current conditions. When a problem occurs in the circuit, the tripping movement is propelled by either a heatsink or solenoid bimetal.

Once the heatsink surpasses its specific trip thresholds, they expand and push the trip pin to open the circuit breaker\'s contacts. This breaks the current flow and prevents further damage. The solenoid bimetal works similarly but, instead of using a heatsink, it’s a metal plate that includes a coil with two different metals wire wrapped together, each with its own expansion degree. When the electric current passes through the bimetal, it will either expand or contract, depending on the magnitude of the electric current. When this expansion or contraction exceeds a certain threshold, the trip pin is activated and the circuit breaker\'s contacts open.

In addition, this circuit breaker is also equipped with a permanent magnet. This magnet offers a steady magnetic force that allows the current to pass until the current value surpasses the predetermined threshold. When this happens, the magnetic field reacts to the surplus current and push the trip pin, thereby switching off the circuit breaker.

Conclusion

The IUGZX2-35599-20 circuit breaker can be used for a wide range of residential and commercial applications. Its effective thermal-magnetic tripping protects the circuit from potential overload or short-circuit issues. This ensures that all electrical components in the circuit remain safe and undamaged.
