Circuit Breakers are a key components of electrical systems used to provide protection against electric shocks and fire hazards. The IUG21-39918-20 is a type of circuit breaker and is commonly used in industrial and residential applications. This article will discuss the application field and working principle of the IUG21-39918-20.

The IUG21-39918-20 is a type of air circuit breaker that is designed for breaking up high alternating current. It is a 2-pole thermal-magnetic circuit breaker. The IUG21-39918-20 is particularly suitable for applications with a wiring system of 2.5 to 25 A. It is commonly used in the protection of low-voltage networks. The IUG21-39918-20 is designed for mounting on vertical and flat rails.

The IUG21-39918-20 has a built-in thermal and magnetic protection. The thermal protection is designed to measure the system\'s current fluctuations and trips if the current exceeds the rated continuous current. The magnetic protection will trip if the current exceeds the instantaneous current value. The IUG21-39918-20 also has an adjustable breaking capacity, which allows the circuit-breaking capacity to be adjusted to the desired currents.

The IUG21-39918-20 operates based on the heat generated when electric current passes through a conductor. The current creates a magnetic field and generates heat, which causes the circuit breaker to trip. When an over-current occurs, the magnetic field causes an electromagnet contacts to close, and in turn, the switch contacts are opened and the circuit is disconnected. Additionally, when a short circuit or ground fault occurs, the magnetic field causes the spring-loaded contacts to open and the circuit is disconnected.

The IUG21-39918-20 is mainly used for the protection of short circuits in domestic, industrial and commercial applications. It is suitable for use in environments with a temperature range of -25°C to 70°C. This circuit breaker has a reliable design and is easy to install and use. It is also designed with a high level of safety and can provide reliable protection against electric shocks and fire hazards.

In conclusion, the IUG21-39918-20 is a type of circuit breaker that is commonly used in industrial and residential applications. It has a built-in thermal and magnetic protection and can provide reliable protection against electric shocks and fire hazards. It operates based on the heat generated when electric current passes through a conductor and is suitable for use in environments with a temperature range of -25°C to 70°C. The IUG21-39918-20 is a reliable and easy to use device that can provide reliable protection for short circuits in domestic, industrial and commercial applications.
