Product Description
The S271-K2 is a single-pole circuit breaker intended for use in industrial control and distribution applications where compact protection is required. Built to integrate into standard DIN-rail assemblies, it provides overcurrent protection for AC circuits with typical S271-series ratings used across 230/400 VAC systems. The device is suited for panel builders and maintenance engineers looking to replace or standardize on S271 variants in existing ABB/ASEA Brown Boveri installations. Terminations are designed for secure wiring in control cabinets, and the breaker’s profile supports dense panel layouts without sacrificing accessibility for operation and replacement. While specific trip curves and interrupt ratings are not provided in the source data, the unit aligns with the S271 family known for consistent performance in auxiliary circuits and light distribution branches. Includes the breaker only; accessories such as auxiliary contacts or mounting hardware are not specified. Verify amperage, voltage, and trip characteristics against your system requirements before deployment.
