Circuit breakers are important components in an electrical power system. They help protect the system from dangerous over-currents that can cause damage and even catastrophic failures. The SU3C2UC circuit breaker is a newer generation breaker that provides additional functionality and enhanced safety features. This article will discuss the application fields and working principles of the SU3C2UC circuit breaker.

The SU3C2UC circuit breaker is designed to protect the power systems from over-currents that can arise from equipment faults, supply faults, digital switching operations and other sources. The device works by sensing when an abnormally high current flow is detected, and cutting off the power supply to the affected circuit. This helps to protect the system from further damage or failure.

The SU3C2UC circuit breaker can be used in a variety of applications, including whole-house surge protection, commercial and industrial facility protection, power distribution systems and panel boards. The device can be used to protect circuits with a wide range of current ratings, from low-voltage motor control systems to high-voltage industrial installations. The breaker is also suitable for protection of electronic circuits, such as ESD protection systems and data communications networks.

The SU3C2UC circuit breaker is composed of three major components: a current sensor, a control logic module, and a contactor. The current sensor is responsible for detecting abnormal current levels. When a fault or surge is detected, the sensor sends a signal to the control logic module. The module then makes an instantaneous evaluation of the situation and, if necessary, commands the contactor to open the circuit, thus cutting off the power to the affected circuit.

The logic module is programmed using digital programming techniques, allowing for adjustments and modifications to be carried out according to the requirements of the application. The module also provides various safety features, such as pick-up and trip-off delays or swift discrimination protection, to ensure the safety of the entire power system.

The SU3C2UC breaker is suitable for both indoor and outdoor applications. It has been tested and certified by international standards, and is available with NEMA Type 3, 4X, and 12 enclosures.

The SU3C2UC circuit breaker is an effective and reliable solution for protecting power systems from over-current conditions. With its advanced features and protective capabilities, it is an ideal choice for both commercial and industrial applications.
