Circuit Breakers are electrical safety devices designed to protect wiring and systems from damaging overloads, including short-circuits. IUGN111-29643-1 is a type of circuit breaker usually used as the main switch in lower-power installations. The IUGN111-29643-1 is a thermal-magnetic circuit breaker with a standard frame size of 3 pole and 3-pole / 4-pole with direct and indirect operation. The rated current ranges of IUGN111-29643-1 ranges from 6 to 40 amperes.

The application field of IUGN111-29643-1 includes protection of low power installations in residential, industrial and commercial places, protection of DC system and AC system, autoload control switch, switchgear, switchboard and control equipment. In terms of the working principle, the IUGN111-29643-1 comprises a bimetal, which, when heated by a current, deflects so as to open the circuit breaker contacts. In addition, the IUGN111-29643-1 features an electromagnet with a solenoid coil to hold the contacts closed when the current within the coil is above a certain level. This level is known as the "pick-up current", which is calculated depending on the necessary settings.

When the current on a circuit exceeds the pick-up current, the magnet will exert enough force to override the bimetal, thus forcing the contacts to separate and the circuit will open. At this point, the excess current is diverted to the breaker and is dissipated as heat until its level has dropped back below the pick-up current, at which point the electromagnet will restore the contacts and re-close the circuit. This happens quickly, usually within a tenth of a second, and the circuit is back to normal shortly afterward. The main advantage of this type of circuit breaker is that it can be easily reset whenever required.

The IUGN111-29643-1 circuit breaker is typically made from metal or plastic in order to provide the best possible protection from fire or electric shock. The breaker has an additional cost of protection which includes additional features, such as auto-reset, thermal-magnetic switch and ground fault sensing. All of these features ensure that the IUGN111-29643-1 circuit breaker is suitable for use in many different applications.

The IUGN111-29643-1 also has a high degree of protection against overload and short circuit. The back plate consists of two layers: an Aluminum conductor layer which provides toughness and flexibility, and a steel case layer which provides extra protection against environmental factors. The terminal that connects the terminals to the breaker is also enclosed in the steel case.

In addition, the IUGN111-29643-1 operates at a nominal voltage of 230V AC and has a wide range of adjustable load characteristics. The adjustable overload characteristics enable the users to select either short-circuit protection or overload protection, depending on the application. Moreover, the IUGN111-29643-1 also features a 6A fast transient voltage surge protection which helps protect the circuit from harmful surges.

The IUGN111-29643-1 circuit breaker is a quality product designed for long service life. It is supplied with a 10-year warranty and it is available in various colors and sizes to suit the requirements of different applications. The IUGN111-29643-1 is a reliable and dependable circuit breaker, and can be used in many different types of applications.
