Allen-Bradley 1492-D2C100 Miniature Circuit Breaker

The Allen-Bradley 1492-D2C100 Miniature Circuit Breaker is a two-pole, 10 A device designed for DC high‑voltage protection in industrial power systems. Part of the 1492‑D DC high‑voltage family from Allen-Bradley (Rockwell Automation), this model uses Trip Curve C to provide defined overcurrent response and fast instantaneous trip when fault current is reached. The 1492-D2C100 designation identifies a 2‑pole, 10‑amp version within the 1492‑D family, offering DC interruption capability to guard distribution rails, DC bus sections, and control circuits against short circuits and overloads. Typical applications include control panels for automation equipment, DC drive systems, and other industrial installations where reliable automatic disconnection of a faulty DC supply is required. The device is a molded‑case miniature circuit breaker designed to protect circuitry from overcurrent events while maintaining system safety and continuity for connected equipment.
