Why Choose the ABB S403P-K4 Miniature Circuit Breaker?
The ABB S403P-K4 is a high-performance 3-pole miniature circuit breaker (MCB) designed for reliable overload and short-circuit protection in demanding electrical distribution systems. Part of the ABB S400P range for the SMISSLINE plug-in system, it combines a K tripping characteristic with modular plug-in technology for efficient installation and dependable circuit protection.
The S403P-K4 is a current-limiting circuit breaker incorporating a delayed thermal tripping mechanism for overload protection and an electromechanical tripping mechanism for short-circuit protection. Its plug-in construction is specifically designed for the SMISSLINE system, supporting efficient assembly, maintenance and replacement within compatible electrical distribution installations.
With a rated current of 4 A, a K tripping characteristic and an ultimate short-circuit breaking capacity of 40 kA, the S403P-K4 provides robust protection for demanding commercial and industrial circuits. Its 3-pole configuration makes it particularly suitable for three-phase applications requiring coordinated protection and switching.

Reliable Three-Phase Circuit Protection for SMISSLINE Systems
The ABB S403P-K4 uses two complementary tripping mechanisms to protect electrical circuits against overcurrent conditions. A delayed thermal mechanism responds to sustained overloads, while an electromechanical mechanism provides rapid disconnection during short circuits, helping protect cables, conductors and connected equipment.
ABB’s SMISSLINE system uses modular plug-in distribution technology to simplify the installation and replacement of protective devices. The S403P-K4 combines this plug-in concept with a K characteristic, three-pole construction and 40 kA breaking capacity, making it suitable for professional three-phase distribution applications where compact construction and high short-circuit performance are required.
Typical Applications
- Industrial three-phase electrical distribution systems.
- Commercial switchboards and distribution panels.
- ABB SMISSLINE plug-in distribution assemblies.
- Machine and equipment control panels.
- Low-current three-phase branch circuits.
- Circuits supplying inductive loads where a K characteristic is appropriate.
