A product of Eaton Cutler-Hammer, the 140G-HTC3-C50 circuit breaker is a molded case circuit breaker classified under the Eaton 140G series of circuit breakers. The 140G-HTC3-C50 circuit breaker features the HC frame rating. It comes with 125 Amps as the rated current while the interrupting method is a trip unit. The trip unit features the fixed thermal or the fixed magnetic protection options. The frequency rating is 60 Hertz and the circuit breaker features a 50-Amp trip rating. The 140G-HTC3-C50 circuit breaker is specially designed to provide space-saving dimensions. The unit’s dimensions include a length of 3.22 inches, a width of 3.54 inches, and a height of 7.08 inches. The ambient storage temperature range is -40 to 176 degrees Fahrenheit. 

The 140G-HTC3-C50 circuit breaker supports a wide range of mounting options. The users should ensure that the mounting enclosure provides the unit with adequate protection from environmental contaminants. The unit meets various standards, including the IEC 60947-2, the UL489, CSA22.2, CE, and CSA standards. Therefore, it is approved for global applications and it provides a unique performance interrupting or breaking capacity. The 140G series of circuit breakers provide thermal or magnetic tripping and electronic protection devices. This ensures a high interrupting or breaking capacity. The unit’s primary purpose is to provide overcurrent protection. The thermal protection for the control panel is provided either through the use of the bimetallic heater elements similar to the ones that are found in the overload relays, or through the use of electronics. This simulates the operation of the heater element for providing adjustable overcurrent protection for applications.
