S800S-UC
When you need a high-performance selective main circuit breaker for your low-voltage distribution board, the S800S-UC series from ABB is the benchmark. These devices are designed for 3-pole and 4-pole configurations, with rated currents from 100A up to 630A, and a breaking capacity of up to 50kA at 415V AC. They are electronic trip units with ad...
When you need a high-performance selective main circuit breaker for your low-voltage distribution board, the S800S-UC series from ABB is the benchmark. These devices are designed for 3-pole and 4-pole configurations, with rated currents from 100A up to 630A, and a breaking capacity of up to 50kA at 415V AC. They are electronic trip units with adjustable L, S, I, and G protections, ensuring full selectivity and coordination in complex industrial networks. The UC designation indicates a universal current rating, making them suitable for both AC and DC applications, a critical feature for modern hybrid power systems.
These breakers are primarily installed in main distribution boards (MDBs), switchgear assemblies, and critical power infrastructure in sectors like data centers, hospitals, manufacturing plants, and commercial buildings. They are the go-to solution for protecting transformers, generators, and large motor control centers where downtime is not an option. Their robust design and high short-circuit withstand capability make them ideal for installations requiring high fault levels and strict compliance with IEC 60947-2.
Within the S800S-UC category, you will find key subcategories like the S800S-UC 3P and 4P variants. The article codes typically follow a pattern like 'S800S-UC 100A 3P' or 'S800S-UC 630A 4P', where the number indicates the rated current and the suffix denotes the pole configuration. For example, the S800S-UC 250A 3P is a common model for medium-sized industrial feeders. These are not accessories; they are the main circuit breakers themselves, available in various amperage ratings to match your system's load requirements.
