ABB S801S-K32 high-performance 32 A single-pole Type K miniature circuit breaker with up to 50 kA breaking capacity for reliable overload and short-circuit protection.
£60.29
The ABB S801S-K32 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, it combines a 32 A rated current, Type K tripping characteristic and high short-circuit breaking capability for industrial, commercial and other professional distribution applications.
The S801S-K32 is a current-limiting circuit breaker incorporating two complementary tripping mechanisms. A thermal mechanism provides overload protection, while an electromechanical mechanism provides rapid short-circuit protection. Fast arc extinction helps limit fault energy and supports dependable protection of downstream equipment and electrical infrastructure.
With a maximum ultimate breaking capacity of 50 kA at 240/415 V AC, a compact single-pole construction and interchangeable cage terminal, the S801S-K32 is particularly suitable for circuits requiring high fault-current performance. Its Type K characteristic makes it well suited to applications involving motors, transformers and other loads that can produce elevated starting currents. ABB order code 2CCS861001R0537 identifies this specific 32 A model.
Miniature circuit breakers such as the ABB S801S-K32 automatically disconnect a circuit when excessive current results from an overload or short circuit. The thermal trip responds to sustained overload conditions, while the electromechanical trip provides rapid operation during high short-circuit currents, helping protect conductors and connected electrical equipment.
The S800S range is engineered for applications requiring high fault-breaking performance in a compact format. The Type K characteristic makes the S801S-K32 particularly useful for circuits with elevated starting currents, while its current-limiting design and rapid arc extinction help minimise the electrical and thermal stresses associated with short-circuit faults.

The ABB S801S-K32 is a high-performance miniature circuit breaker used to protect electrical circuits against overloads and short circuits in industrial, commercial and other demanding electrical installations.
The S801S-K32 has a rated current of 32 A and uses a Type K tripping characteristic.
The S801S-K32 has an ultimate short-circuit breaking capacity of 50 kA at 240 V AC, with ABB also specifying the S800S-K range as a 50 kA class at 240/415 V AC.
The Type K characteristic is suitable for circuits containing loads with relatively high starting or inrush currents, such as motors and transformers, helping avoid unwanted tripping while maintaining overload and short-circuit protection.
The S801S-K32 complies with IEC/EN 60947-2, IEC/EN 60898-1 and UL 1077.
ABB S800S high-performance miniature circuit breakers provide robust overload and short-circuit protection for demanding electrical systems, combining high breaking capacity, current-limiting performance and compact modular construction.
