Applications
MCBs from the S280 series are standard protection devices for low-voltage distribution boards and control panels in industrial, commercial, and telecom installations. The K-curve characteristic suits circuits with moderate inrush currents such as motor loads and transformer primaries. This 10A, 277V configuration was commonly used in three-phase four-wire systems for branch protection of lighting, small motors, and general loads.
Condition: Used
This ABB S281 K10A 1-Pole DIN Rail Circuit Breaker (S281-K10W) has been inspected and is in good used condition. The breaker body is clean and intact with no cracks or damage to the housing. The toggle handle operates normally and the orange trip indicator window is present and intact, as visible in the photos. Terminal connections appear clean with no corrosion. Short wire stubs are visible at the load-side terminal from prior installation — these are remnants from removal and do not affect function. Normal light surface wear consistent with prior installation is present. Please view our photo set and contact us if you have any questions. Please note: We have multiple units in stock — yours may not be the one shown in the photos, however, it will be similar in condition and function.
