Reliable C-Characteristic Protection for Electrical Circuits
The C tripping characteristic of the ABB S204M-C25 is intended for electrical circuits where equipment may draw a moderate inrush current during energisation. This makes the device suitable for applications where a standard B characteristic may not provide the desired tolerance to normal starting currents.
Thermal protection responds to sustained overload conditions, while magnetic protection provides rapid operation during high-current short-circuit faults. Combined with its 10/15 kA rated breaking capacity, the S204M-C25 provides a practical protection solution for modular AC distribution systems.
Typical Applications
- Commercial electrical distribution systems
- Industrial control and distribution panels
- Building services and electrical installations
- Multi-phase AC circuits
- Circuits supplying equipment with moderate inrush currents
- Control and auxiliary circuits
- Modular distribution boards
- General-purpose circuit protection
