ABB S272K8A DIN Rail Circuit Breaker

ABB S272K8A DIN Rail Circuit Breaker is a compact, DIN-rail mounted protection device rated at 8 A for single-phase circuits up to 415 V AC. The model designation S272K8A signals an 8‑ampere rating (K8A) within ABB’s S272 family, designed for installations where space efficiency on a standard DIN rail is essential. This breaker is intended for installation in distribution panels and control cabinets, delivering reliable interruption during overload or short-circuit events for small to medium power circuits. Its 8 A rating makes it suitable for protecting branch circuits such as lighting runs, receptacle feeders, and modest machine control panels in commercial or light industrial settings. The DIN-rail format supports quick snap-in mounting and easy sequencing with other protective devices in compact electrical distributions, enabling scalable protection as system loads grow. With its ABB heritage, the S272K8A provides consistent, predictable performance in single-phase protection applications, helping to safeguard wiring and equipment while keeping panel layouts tidy and install-insightful.
