How do Breakers work?

The construction of these breakers consists of a frame, contacts, lever, trip unit and an actuator mechanism. The trip unit includes a thermal bimetallic strip that deflects in the event of an overload, thereby opening the contacts. A short circuit fault results in an electromagnetic trip opening the contacts directly.

What are the features of a circuit breaker?

Added protection features: In addition to the circuit breaker protection functionalities such as overload, short circuit protection, other protection features such as over/under voltage protection, over/under frequency protection can be added to the circuits, bolstering the safety mechanism to the circuits and loads.

How solid state circuit breakers are transforming power systems?

With material science advancements, solid-state technology is now playing a crucial role in the modern power systems transformation. After revolutionizing the semiconductor industry, the technology is now penetrating the power systems protection, in the form of Solid State Circuit Breakers (SSCBs), which we cover in this article.

What are circuit breakers used for?

The primary use of these breakers is circuit protection in the event of overload, short circuit and ground faults. The construction of these breakers consists of a frame, contacts, lever, trip unit and an actuator mechanism. The trip unit includes a thermal bimetallic strip that deflects in the event of an overload, thereby opening the contacts.

What is a solid state circuit breaker?

Solid state circuit breakers utilize power semiconductors to make and break the circuit. This is a fundamental shift in how circuits can be protected, since these semiconductors can be switched in the order of nanoseconds as opposed to milliseconds as in the case of traditional circuit breakers.

What is a 100 a frame size breaker?

A 100 A frame size breaker can be configured to operate anywhere between 15 A to 100 A, which is a paradigm shift from the traditional approach, where breakers have been static without the ability to change the breaker rating. With the versatility of the SSCB, it has numerous applications in different industry sectors.
