Overview
The ABB S282-K6H11 miniature circuit breaker is a compact, DIN rail-mounted protection device designed for industrial electrical systems. Featuring a K-curve tripping characteristic, this breaker provides both thermal long-time and instantaneous short-circuit protection. The 2-pole configuration makes it ideal for single-phase applications requiring reliable overcurrent and fault protection. Manufactured in Germany to rigorous electrical standards, the S282-K6H11 delivers proven performance in demanding industrial environments.
Key Features
- K-curve trip characteristic for selective protection of motor and transformer circuits
- Dual-pole design enabling single-phase distribution and circuit segmentation
- Instantaneous break time for rapid fault isolation and system safety
- DIN rail mounting for standard industrial control panel integration
- Thermal-magnetic tripping mechanism combining overload and short-circuit detection
- German engineering and manufacturing quality
Technical Specifications
The breaker is rated for 451–500 V AC operation, making it suitable for high-voltage industrial circuits. Its K-curve characteristic follows international standards and provides tailored protection curves for inductive loads. The 2-pole configuration ensures controlled switching of both phases in single-phase systems. The brown color finish identifies the device within standard DIN rail assemblies.
Typical Applications
- Motor starter circuits requiring K-curve motor-protection characteristics
- Power distribution in industrial control panels and switchboards
- Transformer and inductor load protection
- Single-phase system branch circuit protection
- Interior electrical installations in factories and processing plants
Compatibility & Replacements
The S282-K6H11 is part of ABB’s System pro M miniature circuit breaker family, which includes a range of rated currents and pole configurations. Common compatible models in the S282 series share the same DIN rail mounting footprint and terminal connections. When sourcing replacements or expanding existing installations, verify the rated current (In), number of poles, and K-curve designation to ensure proper circuit protection and compatibility with existing busbars and cable terminals. The device accommodates single, multi, and finely stranded conductors from 0.75 to 35 mm.
