Why Choose the ABB S403M-D10NP Miniature Circuit Breaker?
The ABB S403M-D10NP is a 3P+N miniature circuit breaker (MCB) with protected neutral designed to provide reliable overload and short-circuit protection in commercial and industrial electrical distribution systems. As part of the ABB SMISSLINE TP S400M series, it combines dependable circuit protection with the installation efficiency of ABB's plug-in distribution system.
This pluggable miniature circuit breaker protects three phase conductors plus the neutral conductor, with the neutral protected at 100% of the nominal value of the pole conductor. Its SMISSLINE TP configuration supports efficient installation and replacement within compatible distribution assemblies, helping simplify panel construction and ongoing maintenance.
With a rated current of 10 A, a Type D tripping characteristic and a rated short-circuit breaking capacity of 10 kA, the S403M-D10NP is particularly suitable for three-phase plus neutral circuits containing equipment with high starting or inrush currents. Its four-pole arrangement provides coordinated switching and protection of the three phases and protected neutral.

Reliable Protection for High-Inrush 3P+N Circuits
Miniature circuit breakers such as the ABB S403M-D10NP protect electrical circuits and conductors against excessive current caused by overloads and short circuits. Its protected-neutral configuration extends overcurrent protection to the neutral conductor while providing coordinated switching of the three phases and neutral.
The Type D characteristic is particularly suited to circuits containing equipment that can produce high starting or inrush currents during normal operation. Combined with the SMISSLINE TP plug-in architecture, the S403M-D10NP provides an efficient protection solution for three-phase plus neutral industrial machinery, transformers and other demanding electrical loads.
Typical Applications
- Three-phase plus neutral industrial circuits.
- Motors and equipment with high starting currents.
- Transformers and inductive loads.
- Industrial machinery and automation systems.
- Electrical control and distribution panels.
- ABB SMISSLINE TP modular distribution systems.
