Why Choose the ABB S401P-K4 Miniature Circuit Breaker?
The ABB S401P-K4 is a high-performance 1-pole miniature circuit breaker (MCB) designed to provide reliable overload and short-circuit protection in commercial and industrial electrical distribution systems. Part of the ABB S400P range for the SMISSLINE TP plug-in system, it combines current-limiting circuit protection with a compact plug-in format for compatible distribution assemblies.
The S401P-K4 uses thermal overload protection together with electromagnetic short-circuit protection to safeguard cables, conductors and connected equipment. Its Type K tripping characteristic, specified according to IEC/EN 60947-2, is particularly useful for circuits where higher starting or inrush currents may occur without requiring premature magnetic tripping.
With a rated current of 4 A, a 1-pole configuration and a rated ultimate short-circuit breaking capacity of 40 kA, the S401P-K4 provides robust protection in a compact format. ABB order code 2CCG000413R0001 and GTIN 7612271509835 identify this specific 4 A Type K version.

Reliable Type K Circuit Protection
The ABB S401P-K4 protects cables, conductors and connected equipment against damaging overload and short-circuit currents. Its thermal trip responds to sustained overload conditions, while the electromagnetic trip provides rapid disconnection during short-circuit faults. The Type K characteristic accommodates higher transient starting currents than characteristics intended primarily for low-inrush loads.
The ABB SMISSLINE TP plug-in architecture allows compatible protective devices to connect directly to the socket system, supporting efficient assembly, servicing and modification of electrical distribution installations. With its compact single-pole design, 4 A rating and 40 kA breaking capacity, the S401P-K4 is suited to professional control, auxiliary and distribution applications requiring Type K protection.
Typical Applications
- Industrial electrical distribution systems.
- Machine and automation control panels.
- SMISSLINE TP plug-in distribution assemblies.
- Commercial electrical distribution boards.
- Control and auxiliary circuits.
- Circuits with elevated starting or inrush currents.
- Single-pole branch circuit overload and short-circuit protection.
