IUG2-28780-1

Circuit Breakers are an essential public safety device used to help protect people and vital infrastructure by interrupting electrical circuits and preventing the flow of dangerous electrical current when an overload or short circuit is detected. The IUG2-28780-1 is a type of circuit breaker designed to facilitate the safe and efficient operation of electrical installations over a wide range of currents and voltages.

The IUG2-28780-1 is a current limiting, short-circuit fault protection device that can provide over-current protection and preventing the occurrence of short circuit currents from reaching hazardous levels, especially in installations that include a substation transformer.

The working principle of the IUG2-28780-1 is based on a current transformer that works in conjunction with a low voltage air circuit breaker. The current transformer detects any large and potentially dangerous current passing through the main load. When this occurs, a relay mechanism is activated in the transformer, triggering the breaker to trip, thereby eliminating the current flow.

In addition, the IUG2-28780-1 also provides protection against over-currents on single, multiple and distributed lines in AC systems, particularly those used in medium and high voltage systems. This protection is provided by a special current-carrying trip coil that is integrated into the air circuit breaker.

The IUG2-28780-1 can be used for both indoor and outdoor applications, and is particularly suitable for installations in hazardous areas, such as factories, mines, explosives depots and in outdoor environments, such as water towers, power stations and telecommunications towers.

The device has also been designed with a special external reset that facilitates the device’s resetting, making it easier and quicker to restore power. The IUG2-28780-1 can also be used in combination with other protectors, such as voltage transformers, surge arresters and insulation monitors, to provide additional protection.

The IUG2-28780-1 is designed to offer a high level of safety, efficiency and convenience when used in electrical installations. It is also compatible with other devices, making it easy to integrate into existing systems. Furthermore, its flexibility allows it to be adapted to different applications as needed.

Overall, the IUG2-28780-1 is a reliable and effective current limiting, short-circuit fault protection device that can help protect people, property and vital infrastructure against dangerous electrical currents. It is suitable for a variety of indoor and outdoor applications, has a simple reset mechanism, and is compatible with other devices, making it a valuable safety asset for any industrial or commercial operation.
