The Allen-Bradley/Rockwell Automation circuit breaker with the catalog number 140U-I0C3-C60 is part of the Bulletin 140U series and it is used for system overcurrent protection. The 140U circuit breakers are built in accordance with regulations set out in industry standards such as the UL 489, CE, CSA, and C22.2 (No. 5) standards. These circuit breakers offer thermal-magnetic protection and short-circuit protection, and they will reduce costs by protecting valuable equipment from damage if unexpected current-related events occur. The 140U circuit breakers are constructed for easy mounting and they have compact dimensions that allow for integration into complex industrial systems that are made of a number of different components. The 140U-I0C3-C60 molded case circuit breaker provides the flexibility and adjustability that are necessary to meet the demands of a variety of applications. The circuit breaker comes with a frame size of I and thermal-magnetic/non-adjustable magnetic trip protection and it operates with NEMA starter sizes of 2 or 3.

The 140U-I0C3-C60 circuit breaker has a continuous current rating of 60 Amps and a magnetic trip range of 600 to 1200 Amps. The 140U-I0C3-C60 circuit breaker is intended for operation at 100% to 125% of its current rating and it features a solid-state trip mechanism. The unit has three poles and an interrupting rating or breaking capacity of less than or equal to 100 kiloAmps. The power ratings of the circuit breaker include 10 Horsepower of output at 200 Volts, 20 Horsepower of output at 380 to 415 Volts, 25 Horsepower of output at 460 Volts, and 30 Horsepower of output at 575 Volts. The device is designated for environmental conditions that include an operating temperature range of -25 to 60 degrees Celsius (-13 to 140 degrees Fahrenheit) and a storage temperature range of -40 to 80 degrees Celsius (-40 to 176 degrees Fahrenheit).
