Allen-Bradley 140-MN-0250 NSFB Motor Starter

The Allen-Bradley 140-MN-0250 NSFB Motor Starter is a panel- or DIN-rail‑mountable device that provides start/stop switching and overload protection for three-phase motors in automation and power distribution applications. It features a non-fusible disconnect (NSFB) for safety isolation and is rated at 25 A for the 0250 series, housed in an industrial enclosure designed for control wiring and panel installation. Commonly installed in motor control centers, starter panels, and machine control cabinets, it supports dependable motor control in manufacturing lines, material handling systems, pumps and compressors, HVAC, conveyors, and processing equipment. Maintenance teams, system integrators, and electricians use this starter for motor control panel builds, retrofits, and safe operation of motors in automated systems. Common replacements include the 140-MN-0300 NSFB (higher current) and 140-MN-0200 NSFB (lower current), and it is compatible with industrial motors and contactor control circuits within standard motor control and protection schemes. The product is intended for industrial rated operating conditions and enclosed for control wiring, with mounting configuration depending on model.
