Reliable Protection for High-Inrush Three-Phase Circuits
Miniature circuit breakers such as the ABB S403M-D63 protect electrical circuits and conductors against excessive current caused by overloads and short circuits. The thermal release responds to sustained overload conditions, while the electromagnetic release provides rapid interruption when a short-circuit fault occurs.
The Type D characteristic is particularly suited to circuits containing loads that can produce high starting or inrush currents during normal operation. Combined with the SMISSLINE TP plug-in system, the S403M-D63 provides an efficient protection solution for industrial machinery, transformers and other demanding three-phase applications.
Typical Applications
- Three-phase industrial distribution circuits.
- Motors with high starting currents.
- Transformers and inductive loads.
- Industrial machinery and automation systems.
- Equipment with high normal inrush currents.
- ABB SMISSLINE TP modular distribution systems.
