The 140G-H0F3-C80 molded case circuit breaker with an adjustable thermal-magnetic protection unit or trip unit is a high-performance circuit breaker from the Allen-Bradley 140G molded case circuit breaker series designed for complete short-circuit and thermal overcurrent protection to a wide range of industrial control panel applications. This circuit breaker belongs to the H Frame breaker series, and it is designed for both HACR (Heating, Air-Conditioning, and Refrigeration) and reverse feed use. The 140G-H0F3-C80 circuit breaker, like all H Frame breakers, is rated at 125 Amps (the maximum breaker rating), but it has a continuous current rating of 80 Amps and it is suitable for 80 Amps or lower-rated applications. The 140G-H0F3-C80 circuit breaker has a maximum voltage rating of 600 Volts AC, which makes it suitable for control applications with 230, 460, 575, and 600 Volts AC line input ratings. It has a maximum breaking capacity rating of 100 Kilo Volt-Amps, and a maximum impulse voltage withstand rating of 8 Kilovolts.
The 140G-H0F3-C80 circuit breaker has a thermal trip rating that is adjustable from 56 to 80 Amps, and an adjustable magnetic trip rating from 400 to 800 Amps (10x the breaker rating). The 140G-H0F3-C80 circuit breaker has 3-pole wiring with the bolt-on type of line and load side terminals, and it comes with a standard 1-meter pig-tail wiring terminal for internal accessory options. The 140G-H0F3-C80 circuit breaker is rated for 80% efficiency at a continuous load at 40 degrees Celsius, and like all 140G thermal-magnetic circuit breakers, it is very sensitive to ambient temperature changes above 40 degrees Celsius. The 140G-H0F3-C80 circuit breaker is CE marked and CCC and CSA certified, and it has an approximate shipping weight of 2.65 pounds.
