Dependable D-Characteristic Protection for Higher-Inrush Circuits
The D tripping characteristic of the ABB S301P-D50 is designed for electrical circuits where higher starting or inrush currents may occur during normal equipment operation. This characteristic helps accommodate short-duration starting currents while providing protection against excessive overcurrent conditions.
The thermal protection function responds to sustained overload conditions, while magnetic protection provides rapid operation during high-current short-circuit faults. Combined with its 25 kA rated breaking capacity, the S301P-D50 provides dependable protection for AC distribution and control circuits.
Typical Applications
- Industrial control and distribution panels
- Commercial electrical distribution systems
- Building services and electrical installations
- Single-phase AC circuits
- Circuits supplying equipment with elevated starting currents
- Industrial machinery and equipment circuits
- Control and auxiliary circuits
- Modular distribution boards
