The 140G-H6C3-C70 circuit breaker is a 140G circuit breaker designed and manufactured by Allen-Bradley. Breakers belonging to the 140G family offer a wide range of mounting options, electronic and thermal/magnetic protection, space-saving dimensions, and up to 3000 Amps of current rating. To prevent any equipment damage and injury to the users, the main source of electrical power to the system must be disconnected before the installation or maintenance of the 140G-H6C3-C70 circuit breaker is performed. The enclosure used for housing the breaker should be capable of protecting it from damaging contaminants such as water or corrosive substances.

The dimensions of the H Frame 140G-H6C3-C70 circuit breaker are 90 x 82.5 x 130 millimeters (width x depth x height). The device is a 3-pole molded case circuit breaker with 1.2 kilograms of weight. For optimal operation according to manufacturer specifications, the 140G-H6C3-C70 circuit breaker should be operated at ambient temperatures that are less than or equal to 40 degrees Celsius. Above 40 degrees Celsius, the circuit breaker output will derate. At 415 Volts AC and 120 operations per hour, the manufacturer’s specified electrical life of the 140G-H6C3-C70 circuit breaker is 8000 operations. At 240 operations per hour, the specified mechanical life of the breaker is 25,000 operations. According to the IEC standards, the rated insulation voltage for the 140G-H6C3-C70 circuit breaker is 1 kilovolt. The rated impulse withstand voltage for the 140G-H6C3-C70 circuit breaker is 8 kilovolts. The breaker includes an integrated non-adjustable thermal/magnetic trip system. The current rating of the 140G-H6C3-C70 circuit breaker is 70 Amps. The specified magnetic and thermal trip configurations for the 140G-H6C3-C70 circuit breaker are 700 Amps and 70 Amps, respectively.
