About 140G-H3F3-D12

The Allen-Bradley 140G-H3F3-D12 circuit breaker is a 3-pole circuit breaker with a 35 kiloamps interrupting capacity at 480 Volts AC. It is part of the 140G circuit breaker series which uses the thermal/magnetic trip units to offer protection in the 15 to 800 Amps range and the electronic trip units to offer protection in the 10 to 3000 Amps range. The rated current for the 140G-H3F3-D12 circuit breaker is 125 Amps. The breaker uses an adjustable thermal/magnetic trip system. The thermal trip can be configured between 87 and 125 Amps and the magnetic trip can be configured between 625 and 1250 Amps. For 250 to 500 Volts DC, the rated interrupting capacity of the breaker is 50 kiloamps. For AC voltages at 50 to 60 Hertz, the interrupting ratings are 100 kiloamps, 35 kiloamps, and 18 kiloamps at 240 Volts AC, 480 Volts AC, and 600 Volts AC.





The 140G-H3F3-D12 circuit breaker comes in an H Frame enclosure with a rated insulation voltage of 1 kilovolt and with an 8 kilovolts impulse withstand rating. The dimensions of the circuit breaker are 130 millimeters in height, 82.5 millimeters in width, and 90 millimeters in depth. The weight of this 3-pole breaker is 2.65 pounds. The 140G-H3F3-D12 circuit breaker is rated for an electrical life of 8000 operations at 120 operations per hour and at 415 Volts AC operating voltage. The recommended temperature rating of wire to be used with this circuit breaker is 75 degrees Celsius. The temperature of the air surrounding the 140G-H3F3-D12 circuit breaker should not exceed 40 degrees Celsius because, at higher temperatures, the breaker’s output derates.
