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.
