140G-H0C3-C70

The 140G-H0C3-C70 circuit breaker is a circuit breaker from Allen-Bradley/Rockwell Automation. It belongs to the 140G series molded case circuit breakers. The breakers in this series are approved for global applications under the UL, CSA, IEC, and CCC specifications. The 140G-H0C3-C70 circuit breaker has an interrupting capacity rated at 100 kiloAmps at 480 Volts AC. The breaker has an H frame which has a current rating of 125 Amps. However, the breaker has its current range rated at 70 Amps. The breaker has 3 poles. Additionally, the 140G-H0C3-C70 circuit breaker has the fixed thermal/fixed magnetic protection type. The breaker has a rated insulation voltage of 1000 Volts, a rated impulse withstand voltage of 8 kiloVolts, a mechanical life of 240 operations per hour, an electrical life of 120 operations per hour, and it weighs 2.65 pounds. Although the breaker is assembled in the factory, it supports standard external accessories such as phase barriers, insulators, and end caps.

Note that because it is factory assembled, the Allen-Bradley 140G-H0C3-C70 circuit breaker features a non-interchangeable trip unit that supports long-time and instantaneous trip functions. The breaker contains load side lug terminals. The Allen-Bradley/Rockwell Automation 140G-H0C3-C70 circuit breaker, like other breakers in the same family that are factory assembled, is suitable for reverse feed use. To help in monitoring and troubleshooting, the breaker features a handle on its front side. The handle is used to indicate whether the breaker is ON, OFF, or TRIPPED. Note that when the breaker handle is operated vertically rather than rotationally or horizontally, the upmost position of the handle should be the “ON” position.
