The 140G-M6H3-D80 circuit breaker is a molded case circuit breaker manufactured by Eaton Cutler-Hammer as part of the 140G series. It comes with an operating voltage of 600 Volts AC, an M frame rating of 800 Amps, and 3 poles. It features an interrupt rating of 65 kA at 480 Volts AC, a current rating of 800 Amps, and an insulation voltage rating of 1000 Volts. It also features an impulse withstand voltage of 8 kV and it weighs approximately 26.68 pounds. Additionally, this circuit breaker has an electronic LSI protection type. This 140G-M6H3-D80 circuit breaker is referred to as a molded case circuit breaker because it comes assembled in an enclosure made of insulating material. The 140G molded case circuit breakers like this one come in a current range of 10 to 3000 Amps, and they have dimensions that are suitable even in small spaces. 

The 140G-M6H3-D80 circuit breaker and the whole 140G series of circuit breakers are globally accepted for use in UL, CSA, and CCC rated projects and they are also IEC performance rated. Other features of the molded case circuit breakers like this one include greater customization options and a wide range of accessories for universal use across the world. Further, these devices provide a variety of operating techniques to help make the panel configuration processes quick and easy. In general, the 140G-M6H3-D80 circuit breaker is a special circuit breaker that is uniquely engineered and made to open or close manually and also to open the circuit automatically on a preset overcurrent. Usually, this happens without the circuit breaker getting damaged when it is applied correctly at the proper rating.
