Reliable B-Characteristic Protection for Electrical Circuits
The B tripping characteristic of the ABB S204M-B25 is intended for electrical circuits where relatively low inrush currents are expected during normal operation. This makes the device suitable for general-purpose circuit protection applications where controlled response to starting currents is required.
The thermal protection function 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-B25 provides dependable protection for AC distribution and control circuits.
Typical Applications
- Commercial electrical distribution systems
- Industrial control and distribution panels
- Building services and electrical installations
- Multi-phase AC circuits
- General-purpose circuits with relatively low inrush currents
- Lighting and distribution circuits
- Control and auxiliary circuits
- Modular distribution boards
