Circuit breakers are an important component of any electrical grid, and play a key role in protecting and controlling an electrical system. The IUGH11-1-66-30.0-91 is a type of circuit breaker that provides protection and control in a wide range of applications.

In general, a circuit breaker consists of three main components: a contact system, an arc interruption device, and an actuating device. The contact system consists of two rigid contacts that provide the electrical connection and disconnection of the electrical circuit. The arc-interruption device is used to extinguish the arcing between the contacts during the opening or closing of the circuit. The actuating device provides the required opening and closing of the contacts.

The IUGH11-1-66-30.0-91 circuit breaker is a medium voltage type circuit breaker designed to operate at up to 30kV. It is capable of withstanding up to a 3kA short circuit current. The contact system consists of three carbon-graphite contacts that are mounted on a copper insert. The contact system is designed to withstand both open and short circuit conditions, and provide high level of reliability and safety. The arc-interruption device is a combination of an arc quencher and an arc chute. The arc quencher is used to quickly extinguish the arc, while the arc chute is designed to capture and guide the arc gases away from the contacts. The actuating device is an electromagnetic actuator that can be used to both open and close the contacts.

The IUGH11-1-66-30.0-91 circuit breaker is designed for use in a variety of electrical applications. It is designed for use in medium voltage networks, such as in a distribution substation. It is also designed for outdoor or industrial use, where it may be used to protect equipment from high levels of current, voltage, or other electrical stresses.

The circuit breaker is designed to provide both over-current and over-voltage protection. When an overload or over-voltage occurs, the actuating device will open the contacts, breaking the circuit and thereby preventing damage to the equipment or overload of the system. In addition, the circuit breaker is also designed to provide voltage and current monitoring, as well as control functions. This allows it to be used in applications such as voltage regulation and power distribution.

The IUGH11-1-66-30.0-91 circuit breaker is a reliable and robust product that provides reliable protection and control in a wide range of applications. It is designed to be easy to install and maintain, making it an ideal choice for both industrial and outdoor use. It is a cost-effective solution that is designed to provide superior protection, reliability, and control.
