The 140G-H6C3-C60 circuit breaker is a 3-pole circuit breaker with a 60 Amps current rating. It belongs to the 140G breakers series from Allen-Bradley. The 140G circuit breakers are available in 3-pole and 4-pole versions and they support both electronic and thermal/magnetic trip modules. The 140G breakers can be used for the in-line protection of industrial control panels. The 140G-H6C3-C60 circuit breaker comes in an H-frame enclosure and it has 65 kiloamps interrupting/breaking capacity at 480 Volts AC. The current rating of this circuit breaker is 60 Amps and the configured magnetic and thermal trips are configured at 600 Amps and 60 Amps, respectively. The electrical life of the breaker at 415 Volts AC is 8000 operations (at 120 operations per hour).

The impulse withstand voltage and insulation voltage specifications for the 140G-H6C3-C60 circuit breaker are 8 kilovolts and 1000 Volts, respectively. The ultimate short-circuit breaking capacity ratings are: 100 kiloamps at 220 to 230 Volts AC, 70 kiloamps at 380 Volts AC, 70 kiloamps at 400 to 415 Volts AC, 65 kiloamps at 440 Volts AC, 50 kiloamps at 500 Volts AC, 30 kiloamps at 525 Volts AC, and 15 kiloamps at 690 Volts AC. The storage temperature for the 140G-H6C3-C60 circuit breaker is from -40 to 176 degrees Fahrenheit. The operating temperature should not be allowed to exceed 104 degrees Fahrenheit. The H Frame 140G-H6C3-C60 circuit breaker weighs 2.65 pounds and it has the following dimensions: 120 millimeters x 82 millimeters x 130 millimeters. This circuit breaker should be mounted inside an enclosure where it will be protected from contaminants.
