Product Description
The Allen-Bradley 140G-I3C3-D16 is a robust industrial circuit breaker, frame type 'I', rated at 225 Amps with a 35kA interrupting capacity, providing reliable overload and short circuit protection via fixed thermal (up to 160 Amps) and fixed magnetic (1600 Amps trip) protection. Its 800V insulation and 8kV impulse withstand voltage ensure safe operation in demanding electrical environments, and its durable 3.75-pound design guarantees effective circuit integrity.
Is Your Device Showing These Signs?
The Allen Bradley 140G-I3C3-D16 molded case circuit breaker commonly experiences issues such as nuisance tripping due to incorrect overload settings or thermal magnetic trip unit malfunction. Contact wear and degradation from repetitive switching operations reduce the breaker's interrupting capacity. Internal component failures within the electronic trip unit, including the microprocessor or current sensors, cause erratic behavior. Inspect the breaker for proper calibration, contact integrity, and replace any damaged or worn parts to ensure reliable circuit protection and prevent electrical faults.
