140G-G6C3-C25

The Allen-Bradley 140G-G6C3-C25 circuit breaker is a molded case circuit breaker. It is part of the 140 G series of breakers which come in 9 frame sizes and with ratings from 10 to 3000 Amps. This series of breakers can be used for protection against overloading, ground faults, and short circuits. The 140G-G6C3-C25 circuit breaker is a 3-pole breaker rated for 65 kiloamps interrupting rating or breaker capacity at 480 Volts AC. The 140G-G6C3-C25 circuit breaker is available in a G frame and it has a current rating of 25 Amps. The 140G-G6C3-C25 circuit breaker provides fixed thermal and fixed magnetic protection and it is rated for 25 Amps of thermal trip and 500 Amps of magnetic trip. The thermal-magnetic trip unit is not interchangeable. The rated mechanical life of the breaker is 25,000 operations with 240 operations per hour. The rated electrical life at 415 Volts AC is 8000 operations with 120 operations per hour. The temperature rating for the copper wire in this device should be 75 degrees Celsius.

The 140G-G6C3-C25 circuit breaker can operate at temperatures of up to 40 degrees Celsius without derating. The recommended storage temperature for the device is from -40 to 80 degrees Celsius. The dimensions of the 140G-G6C3-C25 circuit breaker are 76.2 x 70 x 130 millimeters. The approximate weight of the 140G-G6C3-C25 circuit breaker is 1.1 kilograms. To prevent electric shock, the electrical power should be disconnected before the breaker is installed or serviced. The breaker should also be protected from contaminants. Several replacement parts are available for the 140G-G6C3-C25 circuit breaker from Allen-Bradley, including end cap kits, insulators, mounting hardware, metric threads, and flex cable connectors.
