The Allen-Bradley/Rockwell Automation circuit breaker with the product code 140U-I0C3-C30 is made for operating in industrial conditions and it provides compact dimensions for its category. This circuit breaker is part of the 140U product series that offers a variety of circuit breakers with either medium or high interrupting capacities and a choice of different frame sizes. These circuit breakers offer independent manual operation, different methods for overcurrent release, molded case design, air/vacuum/gar break, manual switches, flex cable operating mechanisms, and rotary variable-depth operating mechanisms. These protective devices are globally rated for worldwide application and they are in compliance with standards like the EN-IEC 60947-2, UL 489, CSA C22.2 (No. 5), and the CCC standards. Because Allen-Bradley offers a wide range of products, almost every specific industrial need can be met with the right circuit breaker component.

The 140U-I0C3-C30 circuit breaker operates within a temperature range of -25 to 60 degrees Celsius (-13 to 140 degrees Fahrenheit) and it has a moderate resistance to shock and vibration. The 140U-I0C3-C30 circuit breaker unit comes with a frame size of I and three poles. This model includes a thermal-magnetic/non-adjustable magnetic trip protection type and a magnetic trip range of 500 to 1000 Amps. The continuous current rating is 30 Amps, while the interrupting rating/breaking capacity is less than or equal to 100 kiloAmps. In addition to that, the 140U-I0C3-C30 circuit breaker has a current range of 10 RR. Amps and an IP2X protection class when wired. The specified storage temperature of the 140U-I0C3-C30 circuit breaker is -40 to 80 degrees Celsius (-40 to 176 degrees Fahrenheit).
