The 140G-H2F3-D11 circuit breaker is an Allen-Bradley 140G series circuit breaker. It is an H F Frame breaker with a 110 Amps current rating. The 140G series breakers include several features like current-limiting options which provide a half-cycle interrupt (frames H, J, and K) and 18 to 100 kiloamps interrupting ratings and they are approved for global use by the UL, CCC, CSA, and IEC standards. The molded case 140G-H2F3-D11 circuit breaker is a 3-pole breaker and it uses a thermal/magnetic trip module which is adjustable. The rated current for the 140G-H2F3-D11 circuit breaker is 110 Amps. The magnetic trip range is from 550 to 1100 Amps and the thermal trip range is from 77 to 110 Amps. The interrupting rating or breaking capacity at 480 Volts AC is 25 kiloamps. The interrupting ratings for the breaker according to the UL 489 and CSA 22.2 standards at 50 to 60 Hertz are 65, 26, and 15 kiloamps at 240, 480, and 600 Volts, respectively. 

The breaking capacities at 50 to 60 Hertz for the 140G-H2F3-D11 circuit breaker according to the IEC 60947-2 standards at 220, 415, and 690 Volts AC are 65, 36, and 10 kiloamps, respectively. The breaking capacity (DC) for the 140G-H2F3-D11 circuit breaker according to the IEC 60947-2 standards is 36 kiloamps at 250 Volts DC for 2 poles in series and 500 Volts DC for 3 poles in series. The dimensions of the 140G-H2F3-D11 circuit breaker are as follows: 5.12 inches in height, 3.54 inches in width, and 3.22 inches in depth. Allen-Bradley recommends the manual tripping of the breaker prior to the configuration of the magnetic settings. The breaker should only be installed in a suitable enclosure where it is protected from contaminants.
