The Allen-Bradley 140G-H6C3-C15 circuit breaker is an H-frame molded case circuit breaker. The rated current for the 140G-H6C3-C15 circuit breaker is 15 Amps. The 140G-H6C3-C15 circuit breaker is part of the Allen-Bradley 140G series and it is a 3-pole device. The trip unit used on the 140G-H6C3-C15 circuit breaker is a fixed thermal/magnetic unit. The weight of the 140G-H6C3-C15 circuit breaker is approximately 1.2 kilograms. The H Frame enclosure of the breaker measures 130 x 90 x 82.5 millimeters. The recommended storage temperature range for the circuit breaker is from -40 to 80 degrees Celsius. The recommended operating temperature for the 140G-H6C3-C15 circuit breaker is below 40 degrees Celsius. The copper wire should be used for terminations on the breaker. The wire temperature rating is 75 degrees Celsius, which is determined by testing the circuit breaker at full load current.

The rated electrical and mechanical life for the 140G-H6C3-C15 circuit breaker are 8000 hours and 25,000 hours, respectively. The non-adjustable thermal trip setting for the breaker is 15 Amps and the non-adjustable magnetic trip setting for the breaker is 400 Amps. According to the UL 489/CSA 22.2 standards, the interrupting ratings for the 140G-H6C3-C15 circuit breaker at 240, 480, and 600 Volts AC are 150, 65, and 25 kiloamps, respectively. The breaking capacity ratings for the breaker at 250 Volts DC and 500 Volts DC are 70 kiloamps and 70 kiloamps, respectively. Terminal lugs are not supplied with the 140G-H6C3-C15 circuit breaker and need to be ordered separately. Allen-Bradley recommends that the breaker should be kept free from contaminants. Furthermore, to prevent electrical shock, the power source should be disconnected prior to the installation or servicing of the breaker.
