The Allen-Bradley 140U-I6C3-C30 UL Listed Molded Case Circuit Breaker is a compact circuit breaker from the Allen-Bradley bulletin 140U circuit breaker series that is designed to provide overcurrent protection in a wide range of industrial control applications. This circuit breaker features a smaller footprint design that makes it ideal for tight-panel space applications, and it offers a high interrupting rating within its compact package. The 140U-I6C3-C30Ā Molded Case Circuit Breaker is suitable for reverse feed use (at 240 Volts AC and 480 Volts AC), and it is also suitable for the HACR, control circuit, feeder circuits, and the high-intensity discharge applications.

The 140U-I6C3-C30Ā Molded Case Circuit Breaker has a 3-pole design with an end cap standard terminal for simplified wiring and installation, and it comes with standard steel box lugs with up to 10 pounds on an inch ofĀ fastening torque. It has a standard operating voltage range of 230 Volts AC to 690 Volts AC and a maximum interrupting rating of 65 kA at 480 Volts AC. The 140U-I6C3-C30Ā Circuit Breaker has a trip current rating of 30 Amps and a rated insulation voltage of 750 Volts. This device has a mechanical lifespan rating of about 100,000 operations and an electrical lifespan rating of 10,000 operations. The 140U-I6C3-C30 Circuit Breaker has a fixed thermal/magnetic trip unit made up of a fixed bi-metallic element that deflects heat, causing a trip, and a reverse loop contact that uses a magnetic force created by a current moving in the opposite direction for instantaneous magnetic trip action. The 140U-I6C3-C30Ā Circuit Breaker has a rated operating temperatureĀ range of -8 to 60 degrees Celsius and it can be used at a maximum altitudeĀ of 2000 meters without de-rating.
