IUGN66-28061-2 Circuit Breakers: Application Field and Working Principle

Circuit breakers are important devices in everyday life. They are used in electric energy distribution and automation systems to be able to control, distribute, and protect the circuit and its components from an overload or short-circuit. The circuit breakers have made it possible to prevent unwanted situations and dangerous fault currents that can cause costly damages during electrical outages.

IUGN66-28061-2 is a model of low voltage circuit breaker. It is categorized as an indoor, low-voltage circuit breaker with adjustable overload or short-circuit protection. It is designed to handle fault current or overload current up to 16A with a breaking capacity of 6kA or 10kA. The device also has both manual and automatic reset options so that it can be easily reset as needed.

IUGN66-28061-2 circuit breakers have a wide range of applications. Some of its most popular applications include in residential, commercial, and industrial settings. In residential, the device is used in ground fault circuit interrupters, which are installed in all circuits to protect people from electrocution when working with electricity. In commercial and industrial settings, IUGN66-28061-2 is used in large circuits that need to be heavily monitored and protected from potential fault conditions.

IUGN66-28061-2 also offers various types of protection such as short-circuit protection, thermal protection, overload protection, undervoltage/overvoltage protection, and motor protection. It also offers adjustable overload and short circuit protection with adjustable reset delay time, making it an ideal choice for applications requiring high accuracy and reliable protection.

The working principle of IUGN66-28061-2 involves detecting fault current or overload current in the circuit and automatically tripping the circuit. It is based on thermal and magnetic principles. When the current passes through a coil of copper wire, it induces an electromagnetism in the metal core of the device. This creates a magnetic field around the core, which in turn attracts a trip bar, which closes the circuit breaker. When the fault current or overload current reaches the predetermined level, the trip bar is activated and the contacts of the breaker open, thus tripping the circuit.

The IUGN66-28061-2 also has adjustable overload and short-circuit protection with adjustable reset delay time. The adjustable reset delay time allows the device to be set at the desired reset time so that only short time would be required for the trip, thus preventing the system from overloading. The adjustable overload protection of the device also allows it to be set at the required level so that an overload can be avoided before the fault current reaches the preset level.

IUGN66-28061-2 circuit breakers are used in a wide range of applications since they are reliable and offer high accuracy and protection. Having adjustable overload and short-circuit protection as well as adjustable reset delay time, the device can be easily customized to suit different installations.
