Product Description
The robust Allen-Bradley 140G-M5X4 molded case circuit breaker, an 800 Amp, M-frame device with a 50 kA interrupting rating, offers reliable protection for large electrical systems against overloads and short circuits. Its four-pole design, frame-only current range, 1000V insulation voltage, and 8 kV impulse withstand make it suitable for high-voltage environments. Weighing 33.29 pounds, it provides a mechanical lifespan of 120 operations per hour and an electrical lifespan of 60 operations per hour, ensuring dependable performance in demanding, continuous operations.
Is Your Device Showing These Signs?
The Allen Bradley 140G-M5X4 Molded Case Circuit Breaker commonly experiences issues such as nuisance tripping due to incorrect overload settings or thermal magnetic trip unit malfunction. Field failures often stem from contact erosion caused by repetitive high fault current interruptions, requiring replacement of the breaker. Diagnosing and resolving these problems involves verifying proper amp settings, inspecting for mechanical damage, and performing insulation resistance tests to identify internal shorts or ground faults. Inadequate preventative maintenance, including torque verification of terminal connections and regular visual inspections, contributes to premature degradation and operational failures.
