Circuit breakers are designed to protect electrical power systems from potential damage due to overloads or short circuits. The IUGN6-9900-1 circuit breaker is a single-pole, thermal-magnetic circuit breaker from the "Q Series" manufactured by Schneider Electric. It is designed to provide reliable protection for residential, commercial and industrial systems, for applications such as lighting circuits, HVAC systems and electric motors.

The IUGN6-9900-1 circuit breaker is rated for up to 240 volts AC, with a current rating of 15 A and a break capacity of 10kA at 240 volts. It has an interrupt rating of 50A at 240 volts and an interrupt time of 30ms. The IUGN6-9900-1 is also equipped with a 4mm2 stripping capacity and a 1 pole auxiliary switch.

The working principle of the IUGN6-9900-1 circuit breaker is based on the thermal-magnetic circuit protection mechanism. Thermal protection is provided by a bimetallic strip that operates the circuit breaker when the temperature inside the breaker reaches a preset level, i.e. the thermal rating of the device. The magnetic field is provided by an electromagnet. When an overload current flows through the electromagnet, its field strength increases and the armature is pulled down, operating the circuit breaker.

The IUGN6-9900-1 circuit breaker is suitable for a wide range of applications, including commercial buildings, industrial plants, residential buildings and solar-powered systems. It is particularly well-suited for motor starting and short-circuit protection in buildings, industrial plants and solar systems. Additionally, the device is designed to detect both overcurrent and short circuit conditions, ensuring reliable protection against electrical system damage.

The IUGN6-9900-1 circuit breaker is designed to comply with the international standards and directives for industrial, residential and commercial electrical systems. It is also tested for quality assurance and compatibility with other equipment, consequently being a reliable and cost-efficient choice for electrical protection.
