Eaton MDS625 Low Voltage AC Power Circuit Breaker
The Eaton MDS625 is a 3-pole, 2500A Magnum DS series low-voltage insulated case circuit breaker manufactured by Eaton (Cutler-Hammer). Designed per ANSI/NEMA/UL standards, it provides 100% continuous current rating and high short-circuit interrupting capability for heavy-duty power distribution.
Core Uses
- Main incoming feeder protection in low-voltage switchboards (e.g., Pow-R-Line)
- Motor, transformer, and capacitor bank protection
- Selective coordination in industrial and commercial distribution systems
- Arc flash mitigation and system reliability enhancement
