Reliable Protection for Electrical Installations
The ABB S203M-D6 uses thermal and magnetic tripping mechanisms to protect electrical circuits from overload and short-circuit faults. The delayed thermal trip responds to sustained overloads, while the electromechanical magnetic trip provides rapid disconnection during short-circuit conditions.
Its D curve characteristic is designed for applications where higher starting currents are expected. This helps reduce nuisance tripping during energisation while maintaining effective protection for cables, equipment and electrical installations.
Typical Applications
- Industrial control panels.
- Commercial electrical distribution boards.
- Transformer and solenoid circuits.
- Power supplies and automation equipment.
- Motor control circuits with high inrush currents.
- OEM machinery and panel building applications.
