The Allen-Bradley 140G-G6C3-C90 circuit breaker is a molded case circuit breaker with a 90 Amps current rating and a non-interchangeable thermal-magnetic trip unit. This protective device belongs to the 140G series of circuit breakers manufactured by Allen-Bradley. The 140G-G6C3-C90 circuit breaker is designed and produced to cover commercial and industrial applications. The 140G-G6C3-C90 circuit breaker is factory assembled, and it does not support field installations of internal parts. As standard external accessories, this 3-pole circuit breaker has end cap terminals, 25-millimeter phase barriers, and backplates. Users can acquire the following external accessories: terminal lugs, extended terminals, padlocks, terminal covers, and motor operator devices.

 

The Allen-Bradley 140G-G6C3-C90 circuit breaker has 3 possible states: ON, OFF, and TRIPPED. To manually test the device (which is recommended at least once every 6 months), the users can push the test button located on the center pole of the thermal-magnetic trip unit. The 140G-G6C3-C90 molded case circuit breaker has an AIC rating of 65 kA at 480 Volts AC, 10 kA at 690 Volts AC, and 70 kA at 500 Volts DC. The maximum continuous current rating of this G-frame circuit breaker is 125 Amps. The entire 140G series of molded case circuit breakers are characterized by high reliability and precision of reacting to a precisely defined current value. These dependable devices are the result of Allen-Bradley's years of investment in the technical development of devices that will have high-quality materials and components and yet be affordable for customers. The 140G-G6C3-C90 circuit breaker provides protection to the users, property, and business processes. It reduces downtimes by de-energizing only the sections of the system where the electrical problem is detected.
