Why Choose the ABB S403M-D6 Miniature Circuit Breaker?
The ABB S403M-D6 is a 3-pole miniature circuit breaker (MCB) designed to provide dependable overload and short-circuit protection in three-phase electrical circuits. Part of the ABB S400M range for the SMISSLINE TP plug-in system, it combines a 6 A rated current, Type D tripping characteristic and 10 kA short-circuit breaking capacity.
The S403M-D6 uses thermal and electromagnetic tripping to protect conductors and connected equipment against sustained overloads and short-circuit faults. Its Type D characteristic is intended for appropriately designed circuits with comparatively high starting or inrush currents, making it particularly useful where conventional loads may produce substantial temporary current peaks.
With 3 poles, a 400 V AC rated voltage and compact three-module construction, the S403M-D6 provides coordinated protection for three-phase applications. Its SMISSLINE TP plug-in design allows straightforward integration into compatible ABB distribution systems while retaining the protection performance required for industrial and commercial installations.

Reliable Type D Three-Phase Circuit Protection
The ABB S403M-D6 protects electrical circuits against excessive current resulting from overloads and short circuits. Its thermal release responds to sustained overload conditions, while the electromagnetic release provides rapid interruption when a short-circuit fault reaches the instantaneous tripping range.
The combination of a 6 A Type D characteristic, 3-pole construction and 10 kA breaking capacity makes the S403M-D6 particularly useful for appropriately engineered circuits where higher temporary starting currents are expected. Its SMISSLINE TP plug-in construction also supports efficient integration into modular industrial and commercial distribution systems.
Typical Applications
- ABB SMISSLINE TP three-phase distribution systems.
- Industrial control and auxiliary circuits.
- Automation and machine-control panels.
- Appropriately designed motor and inductive-load circuits.
- Transformer and equipment circuits with elevated inrush currents.
- Commercial and industrial switchboards requiring 6 A Type D protection.
