ABB PR211 Circuit Breaker is a three-pole device built on the S4/S4N frame, rated for 600 V and 150 A, designed to protect three‑phase circuits in industrial power-distribution systems. It ships with a PR211/P electronic release and a shunt release option, including a short wire for remote tripping. This combination supports remote protection in control panels and switchgear, enabling fast isolation of faulted or overloaded conductors while meeting standard low- to medium-voltage protection needs in industrial environments.
