Circuit breakers are essential components of any electrical system that are designed to protect against electrical overloads and short circuits. A circuit breaker’s main job is to detect abnormal circuit conditions and rapidly open and break the electrical circuit when it does. SU1C50UC circuit breakers are designed for medium-voltage applications as a cost-effective solution for applications where current levels may exceed the specified ratings of a lower voltage rated circuit breaker.

The SU1C50UC circuit breaker is a type of medium-voltage circuit breaker. It is a 1000-volt class, 50 kA, 3-pole breaker with adjustable instantaneous trip settings. The breaker has a unique adjustable magnetic trip mechanism, which is responsible for detecting and tripping on various current transgressions. This adjustable magnetic trip mechanism ensures the accurate tripping of the breaker when the current exceeds the desired trip setting. The mechanism also helps to prevent disturbances or damage to the other electrical components in the system.

The SU1C50UC circuit breakers also have a reset-prevent mechanism which ensures that the breaker can only be reset after a brief time-out period. This time-out period is adjustable and ranges from 1 second to 9 hours. This mechanism helps to prevent unintentional resetting of the breaker due to current transients or other anomalous situations that may occur in the system.

The SU1C50UC circuit breakers also feature a built-in ground fault detection system that helps to detect any ground faults and the subsequent disconnection of the ground faulted circuit. This feature helps to improve the efficiency and reliability of the breaker while also improving personnel safety in the event of a ground fault.

Finally, the SU1C50UC circuit breakers feature a selection of accessories that can be used to customize the breaker for specific applications. These additional components include auxiliary contacts, thermal-magnetic trip units, and electronic trip units. All these accessories help to improve the performance and safety of the breaker, making it ideal for a range of medium-voltage applications.

In summary, the SU1C50UC circuit breakers are designed for a range of medium-voltage applications and provide a cost-effective solution for applications which may exceed the ratings of a lower voltage rated circuit breaker. They feature a unique adjustable magnetic trip mechanism, a reset-prevent mechanism, an integrated ground fault detection system, and a range of accessories to aid in their customizability. This makes them ideal for a wide variety of applications ranging from residential, industrial, and commercial applications.
