Circuit Breakers

Circuit breakers are electrical devices specifically designed to provide protection against overload current and short-circuiting in electrical circuits. The IUGH111-1REC4-40280-4 is a particular type of circuit breaker used in residential and industrial applications to provide safe, reliable, and effective protection from overcurrent and short-circuit hazards. This article will discuss the application field and working principle of the IUGH111-1REC4-40280-4.

Application Field

The IUGH111-1REC4-40280-4 circuit breaker is widely used in residential, commercial, and industrial power supply systems. In residential applications, the device is designed to protect kitchen appliances, fans, televisions, air conditioners, and other electrical equipment from overload and short-circuit hazards. The device is also suitable for use in commercial buildings, such as hospitals, office buildings, and shopping centers, to protect industrial machines, office equipment, and communication systems. In industrial applications, the device is used to protect heavy-duty machines, production lines, and electronic control systems.

Working Principle

The IUGH111-1REC4-40280-4 circuit breaker consists of a single-pole, shunt-operated thermal-magnetic mechanism which is connected in series with the electrical circuit. When the electrical load in the protected circuit exceeds the rated current of the device, a thermal response of the device causes its contacts to open, thereby interrupting the current flow and releasing the overload current. In the event of a short circuit or overcurrent, the magnetic response of the device causes its contacts to also open, thus providing a high level of protection from electric shocks.

The IUGH111-1REC4-40280-4 circuit breaker also includes an auxiliary contact that can be used to control other electrical circuits. This contact is connected in parallel with the main contact and is used to open other circuits in the event of an overload or short circuit. This feature ensures that all associated circuits are quickly shut down in order to prevent further damage or injury.

The device also includes current-limiting capability, which is used to reduce the risk of damage from inrush currents. This feature works by using an automatic reset feature to limit the current flow to a safe level. This helps to ensure safe and reliable operation of the system even in the case of a short circuit.

Conclusion

The IUGH111-1REC4-40280-4 circuit breaker is a highly reliable and effective device for residential, commercial, and industrial applications. This device provides protection from overcurrent and short-circuit hazards, and includes features such as current-limiting and auxiliary contacts for controlling additional circuits. When properly installed and maintained, this device can provide reliable and safe operation in a wide range of applications.
