Bradley 140-MN-2000 Motor Circuit Breaker

Allen‑Bradley 140-MN-2000 Motor Circuit Breaker is a motor protection device from Rockwell Automation’s 140MN family, designed to interrupt motor current when overloads or faults occur to protect motors and wiring in industrial panels.

Used in motor control centers and panel installations, it serves as the protective element in a complete motor protection scheme and is typically paired with compatible overload relays and standard control circuitry to guard AC motors such as pumps, fans, conveyors, and machine tools.

The 140-MN-2000 designation identifies a specific model variant within the 140MN lineup, with the exact electrical ratings, mounting options, and installation requirements defined by the corresponding product datasheet and installation guidelines. This family emphasizes reliable tripping performance in industrial environments while maintaining a compact form factor suitable for panel spaces and standard electrical enclosures.
