Overview

Solid-State Circuit-Breaker for DC applications with unidirectional or bi-directional power flow such as batteries, electrolyzer and other DC loads.

Security at its Best

SSCB is designed to open high short circuit currents in a few microseconds through its high electrical features. SSCB is presented as a solution where fuses do not guarantee a proper protection selectivity or where the availability is critical.

The SSCB complies with the most demanding safety codes in the world adapting to the necessities of the market. SSCB is a solution designed and patented by Hitachi Energy and it uses an innovative solution to minimize the overvoltage in the fault opening. With an easy integration and low power consumption, these devices allow remote monitoring and control, as well as a high-performance protecting facility from short circuit events.
