Allen-Bradley 140M-F8E-C25 Molded Case Circuit Breaker

The Allen-Bradley 140M-F8E-C25 is a 3-pole molded case circuit breaker designed for adjustable thermal-magnetic overcurrent protection in industrial motor control and feeder circuits. It combines thermal overload and magnetic short-circuit protection with a 25 A rated current and an adjustable current range within the F frame to suit varying motor loads. The unit supports DIN-rail or panel mounting and is intended for industrial AC systems, with the exact rated voltage and short-circuit interrupt rating determined by the application. Typical installations include motor control centers, control panels, and industrial machinery where protection for three‑phase motors, drives, and feeder circuits is required. Common replacements include Allen-Bradley 140M-F8E-C32 and Schneider Electric GV3P25.
