The 140G-H0C3-C40 circuit breaker is a molded case circuit breaker designed and manufactured by Allen-Bradley/Rockwell Automation. It has an interrupting capacity of 100 kiloAmps at 480 Volts AC. The 140G-H0C3-C40 circuit breaker supports a maximum voltage of 600 Volts AC that is supplied by a 3-phase power source and it has a current rating of 40 Amps. The breaker features a non-interchangeable trip unit. For mounting, this circuit breaker supports a bolt-on connection. Also, the 140G-H0C3-C40 circuit breaker has instantaneous trip functions and it also has load side lug terminals. The 140G-H0C3-C40 circuit breaker is part of the thermal-magnetic family of Allen-Bradley circuit breakers with a molded case in the 140G series. Breakers in this series employ different types of overcurrent releases such as instantaneous, definite time delay, and inverse time-delay overcurrent releases.

The Allen-Bradley 140G-H0C3-C40 circuit breaker, like other Allen-Bradley molded case circuit breakers, is used to provide overcurrent protection for the conductors and equipment by opening automatically before the current reaches a value and a duration that is capable of causing harmful effects. Some dangerous effects include but are not limited to, extreme temperatures in the conductors or the conduction insulation. Note that some types of molded case circuit breakers can be used to protect motor circuits. The Allen-Bradley 140G-H0C3-C40 circuit breaker has an H Frame size. The frame has a current rating of 125 Amps. The breaker’s rated insulation voltage stands at 1000 Volts. Without derating, the 140G-H0C3-C40 circuit breaker has its operating voltage rated at 40 degrees Celsius while its storage temperature ranges from -40 degrees Celsius and 80 degrees Celsius. The 140G-H0C3-C40 circuit breaker measures 90 millimeters by 82.5 millimeters by 130 millimeters.
