Circuit Breakers are devices designed to protect electrical circuits and equipment from overloading and short circuit conditions. One type of circuit breaker is the IUGN666-1-41-40.0-A.

The IUGN666-1-41-40.0-A application field is primarily pre-fault applications and short circuit protection. It is suitable for use in a variety of residential, commercial, and industrial applications.

The IUGN666-1-41-40.0-A contains a trip-fuse with a rating of 40A, an arcing horn of 6.45, and a socket for connection to other devices. The trip-fuse is designed to activate automatically when the current overloads or short circuits, disconnecting the circuit and protecting it from further overloads or short circuits.

The IUGN666-1-41-40.0-A also contains a delayed-action tripper. This device is designed to delay the trip of the fuse, allowing the current to continue to flow, at a reduced level, for a few seconds before the circuit is finally disconnected. This delay allows downstream electrical equipment time to react and prevent further overload problems.

The working principle of the IUGN666-1-41-40.0-A is as follows. When an overload is detected, the trip-fuse connects to the main power line, and a signal is sent to the delayed-action tripper. The delayed-action tripper then starts to open the circuit slowly, reducing the current, while the arcing horn is activated. After a few seconds, the tripper is fully opened, the circuit is disconnected and the arcing horn is silenced.

The IUGN666-1-41-40.0-A provides protection against overload currents and short circuit currents, making it an ideal device for a variety of electrical applications. Its delayed-action tripper allows additional time for downstream electrical equipment to respond, preventing further overloads and short circuit conditions.
