High-Performance Circuit Protection
Miniature circuit breakers protect electrical circuits against excessive current caused by overloads and short circuits. When current exceeds the permitted operating range, the breaker disconnects the protected circuit, helping to prevent damage to cables, equipment and electrical installations.
The ABB S800 range is engineered for applications requiring high interruption performance. The S804S-UCK8 combines a four-pole arrangement with a K characteristic and an 8 A current rating, making it particularly suitable for industrial circuits containing loads that can produce elevated starting currents while still requiring dependable overcurrent and short-circuit protection.
Typical Applications
- Industrial electrical distribution systems.
- Machinery and automation control panels.
- Motor and inductive-load circuits with elevated starting currents.
- Industrial power supplies and control equipment.
- Manufacturing and production machinery.
- Electrical switchboards and distribution assemblies.
