2CCS861002R1537 ABB S801S-UCK32-R High Performance MCB 50kA 1P Type K 32A

Why Choose the ABB S801S-UCK32-R High Performance MCB?

The ABB S801S-UCK32-R is a high-performance single-pole miniature circuit breaker (MCB) designed to provide reliable overload and short-circuit protection in demanding electrical installations. Part of the ABB S800S high-performance circuit breaker range, this model combines a 32 A rated current, Type K tripping characteristic and 50 kA breaking-capacity class.

The S801S-UCK32-R combines thermal overload protection with rapid electromagnetic short-circuit tripping. Its Type K characteristic is particularly suited to circuits containing equipment with elevated starting or inrush currents, helping accommodate normal transient currents while maintaining dependable protection against sustained overloads and short circuits.

With its 1-pole configuration, current-limiting operating principle and robust S800S construction, the S801S-UCK32-R is well suited to industrial machinery, motor, transformer and other inductive-load circuits. ABB order code 2CCS861002R1537 identifies this specific 32 A Type K model.
