Aut.S280K: High-Performance Molded Case Circuit Breakers (MCCBs) for Industrial Automation
The Aut.S280K series represents a premium line of molded case circuit breakers (MCCBs) designed for rigorous industrial and commercial applications. These devices are engineered to provide reliable overcurrent and short-circuit protection, with ratings typically ranging from 16A to 630A in 3P or 4P configurations. Key technical specifications include a breaking capacity (Icu) up to 50kA at 415V AC, adjustable thermal and magnetic trip units for precise coordination, and a compact frame size that optimizes panel space. The S280K series supports fixed or plug-in mounting, with accessories like shunt trips, undervoltage releases, and auxiliary contacts for remote monitoring. Rated for operational voltages up to 690V AC and frequencies of 50/60 Hz, these breakers meet IEC 60947-2 standards, ensuring global compliance. Known globally as MCCBs, circuit breakers, or automatic switches, the Aut.S280K line is synonymous with durability and precision in electrical protection.
These circuit breakers are ideal for installation in distribution boards, motor control centers (MCCs), and automation panels across sectors like manufacturing, energy, and infrastructure. Common applications include feeder protection in industrial plants, branch circuit protection in commercial buildings, and backup protection for transformers and generators. The S280K series excels in environments requiring high short-circuit withstand, such as heavy machinery lines, HVAC systems, and data centers. Its adjustable trip settings allow engineers to fine-tune protection for specific loads, reducing nuisance tripping while ensuring safety. In renewable energy setups, these breakers protect inverters and battery storage systems, while in oil and gas, they safeguard critical motor circuits. The series is also widely used in shipboard electrical systems and mining operations, where reliability under harsh conditions is paramount.
The Aut.S280K category includes several subcategories and key article codes, such as the S280K-63A (3P, 63A, 25kA), S280K-160A (4P, 160A, 36kA), and S280K-400A (3P, 400A, 50kA). The article code structure typically follows the pattern: [Series][Amperage][Poles][Breaking Capacity], e.g., S280K-250A-3P-36kA. Other notable variants include the S280K-100A (4P, 100A, 25kA) and S280K-630A (3P, 630A, 50kA). These codes are standardized across the series, enabling easy identification of key parameters like rated current, number of poles, and short-circuit capacity. Accessories like the S280K-AUX (auxiliary contact) and S280K-SHT (shunt trip) are also available, but the main focus remains on the core breaker units for direct circuit protection.
