Intelligent low voltage circuit breaker releases energy and stores energy

What is a low-voltage DC circuit breaker?

In particular, the low-voltage dc circuit breaker has been arousing great research interest in recent years. In this type of circuit breaker, an air arc is formed in the interrupting process which is a 3D transient arc in a complex chamber geometry with splitter plates.

What is a solid-state circuit breaker (ABB)?

A technological breakthrough by ABB – a solid-state circuit breaker – will enhance performance of renewable energy solutions, industrial battery storage solutions and so-called edge grids.

When will a ground-breaking low voltage circuit breaker be available?

The ground-breaking low voltage circuit breaker concept will be revealed to the public for the first time at the Hannover Messe in Germany. The product will be available from 2020.

What is a solid-state circuit breaker?

The solid-state circuit breaker will be around 100 times faster than traditional electro-mechanical breakers. Its speed maximizes the performance of power distribution systems, while maintaining service continuity. The new ABB breaker will also improve safety and protection for people and equipment.

What is an ABB breaker?

Developed in Italy at ABB’s Bergamo Electrification business R&D Center, the ABB breaker concept is the first of its kind to use a patented integrated gate-commutated thyristor (IGCT) semiconductor technology.

How does a solid-state breaker work?

The ABB solid-state breaker concept works by replacing the traditional moving parts of an electro-mechanical circuit breaker with power electronics and advanced software algorithms that control the power and can interrupt extreme currents faster than ever before.
