two-step stored energy mechanism makes this possible. Once the closing spring is charged, it lies paused and ready to rapidly reclose the circuit breaker. The major advantages of the two-step stored energy mechanism are rapid reclosing and safety .
The circuit breaker diagram provides a visual representation of how the various components of a circuit breaker work together to ensure the safe operation of an electrical system. It includes several key elements, such as the circuit breaker itself, the trip unit, the shunt trip, and the auxiliary contacts.
The general design methodology of iBreaker is discussed in this section. Figure 4.1 shows four key design elements: use of WBG switch for mΩ-range on-resistance, tri-mode operation for integrating intelligent functions, combined digital and analog control for both speed and flexibility, and universal hardware/software architecture for easy commercialization.
