The 140U-H6C3-C15-A circuit breaker is a motor protector circuit breaker designed by Allen-Bradley. It is a three-pole circuit breaker with a current rating of 125 Amps. It comes enclosed in a conformally coated H Frame. The conformal coating of the breaker helps to protect it against dust and dirt and harmful gas and vapors in an industrial environment. The 140U-H6C3-C15-A circuit breaker comes with a voltage rating of 480 Volts AC. The circuit breaker can interrupt the system at 65 kA. The cureent rating of the breaker is 15 Amps. The device comes with a fixed thermal and a fixed magnetic trip. The circuit breaker can protect electrical circuits from short circuits as well as overloads (both electrical and thermal overloads). The 140U-H6C3-C15-A circuit breaker is manufactured using high-quality materials, which results in better performance for a longer period of time.

Depending on the applied load, the 140U-H6C3-C15-A circuit breaker operates with 2 different frequencies of 50 and 60 Hertz. The device measures 2.99 inches in length, 3 inches in width, and 5.5 inches in height. The 140U-H6C3-C15-A circuit breaker comes with flex cable operating mechanisms. It supports factory or field-installed accessories. This molded case circuit breaker is comprised of different components that can be easily replaced. The 140U-H6C3-C15-A circuit breaker supports long-time instantaneous trip functions. It comes with a current limiting feature that can set an upper limit on the current that is being delivered to a load. This is done to protect the circuit from the harmful effects of short circuits. The breaker can be easily used at an altitude of 2000 meters maximum above sea level without getting derated.
