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 is a P-frame circuit breaker?

Providing unparalleled performance and control, the P-frame circuit breakers features the exclusive MicroLogic electronic trip units, which allow for a range of sophisticated applications for metering and monitoring. In addition, trip units can be interchanged in the field to allow for maximum flexibility.

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.

Do Allen-Bradley circuit breaker frames have a magnetic trip mechanism?

Allen-Bradley G-frame and H-frame (up to 70 A) circuit breakers have a non-adjustable, instantaneous magnetic-trip mechanism that is set by the circuit breaker manufacturer. All other frame sizes have an adjustable, instantaneous trip mechanism that can be set to a desired current value. See Table 8 for the instantaneous trip ranges and settings.

What is a compact circuit breaker?

ComPacT circuit breaker size allows for small footprint installations using I-Line panelboards and switchboards. Nine inch width provides increased density installation. Selection of four interchangeable MicroLogic trip units available, with PoweLogic power metering and monitoring capabilities available in advanced trip units.

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.
