ABB has expanded its miniature circuit-breaker range with a high-performance series. Replacing the S500 series, the S800 series offers two levels of breaking capabilities.

The S800S is aimed at the industrial sector and provides breaking capacities of up to 50 kA, while the S800N is suitable for commercial applications and offers breaking capacities of up to 36 kA.

Both ranges have current ratings available up to 125 A and rated voltages of up to 690 V and are available in one, two, three or four-pole versions.
