Why Choose the ABB S803S-UCK16-R High Performance MCB?
The ABB S803S-UCK16-R is a high-performance three-pole miniature circuit breaker (MCB) designed to provide reliable overload and short-circuit protection in demanding industrial electrical systems. Part of the ABB S800S high-performance MCB series, this model combines a 16 A rated current, K tripping characteristic and high 50 kA short-circuit breaking capacity for robust circuit protection.
The S803S-UCK16-R uses thermal and electromagnetic tripping mechanisms to protect conductors and connected equipment against sustained overloads and short-circuit faults. Its K characteristic is particularly suitable for circuits supplying motors, transformers and other inductive loads where comparatively high starting currents need to be accommodated without unnecessary tripping.
With three protected poles and a specified 50 kA short-circuit breaking capacity, the S803S-UCK16-R is engineered for installations where high prospective fault currents may occur. The -R ring-terminal connection version supports secure electrical termination, while the ABB order code for this exact breaker is 2CCS863002R1467.

Reliable Protection for Motor and Inductive Circuits
The ABB S803S-UCK16-R combines thermal overload protection with rapid electromagnetic short-circuit protection. The thermal mechanism responds to sustained excessive current, while the magnetic trip mechanism rapidly disconnects the circuit during severe fault conditions, helping protect conductors, machinery and connected electrical equipment.
The K tripping characteristic accommodates the starting currents commonly associated with motors, transformers and other inductive equipment while maintaining effective fault protection. Combined with the high fault-interruption capability of the S800S platform, the S803S-UCK16-R is well suited to industrial circuits requiring dependable 16 A three-pole protection.
Typical Applications
- Industrial three-phase electrical distribution systems.
- Motor supply and machinery circuits.
- Transformer and inductive-load circuits.
- Industrial control panels and switchboards.
- Manufacturing and production equipment.
- Automation and material-handling systems.
