Circuit breakers, otherwise known as short-circuit protectors or short-circuit limiters, are devices used to protect against electrical system overload or short circuits. They are a component that belongs to the electrical protection system, allowing circuits to open and close when a predefined threshold of voltage is exceeded or short-circuits occur.

One such circuit breaker is the IUGX66-3680-2. It is a three-phase, high grade automatic short-circuit protective device that complies with stringent UL489 and IEC standards. It is designed to provide reliable short-circuit protection of residential, commercial, industrial, and institutional applications.

Application Field

The IUGX66-3680-2 is suitable for use in a variety of applications, from residential, commercial, and industrial to institutional. In residential applications, it protects against overload from household appliances, while in commercial and industrial applications it prevents short-circuits from occurring in machines and equipment. For institutional applications, the circuit breaker is used to protect critical electrical systems, such as hospital equipment and fire alarm systems, from short-circuits.

Working Principle

The working principle of the IUGX66-3680-2 is simple. The circuit breaker is equipped with a thermal magnetic release, which is triggered by an increase in the current flowing through the circuit. When the current exceeds the threshold set by the thermal magnetic release, the circuit breaker trips, opening the circuit and protecting against overload or a short-circuit. The thermal magnetic release can be reset by pressing the reset button.

The IUGX66-3680-2 also features a manual override switch, allowing the user to manually open the circuit breaker if necessary. This feature is especially useful in the event of an unexpected power failure, as it allows the user to quickly restore power to the affected system.

In addition to the thermal magnetic release, the IUGX66-3680-2 is also equipped with a current limiting function, which prevents excessive current from flowing through the circuit in the event of a short-circuit. This provides additional protection against electrical system overload or damage.

The IUGX66-3680-2 is a reliable and highly efficient circuit breaker, ideal for a wide range of applications. Its thermal magnetic release, manual override switch, and current limiting function make it a versatile and reliable choice for protecting electrical systems from overload or short-circuits.
