The Allen-Bradley 140U-H6C3-C30-MT circuit breaker is a molded case circuit breaker with a fixed magnetic and thermal trip rated at 30 Amps. The breaker is enclosed inside a 125 Amps rated frame molded case. The interrupt rating of the breaker is 65 kA at 480 Volts AC. It has three poles and it can be used with both single-phase and three-phase applications. The breaker comes with a shunt trip, undervoltage release, and a left side mounting orientation. The breaker also comes with an alarm feature that alerts the operators for current overload and short circuit conditions. The 140U-H6C3-C30-MT circuit breaker is equipped with terminal lugs which are installed by default. The voltage rating of the breaker device is 480 Volts AC and it operates with a frequency of 60 Hertz. The current limiting feature is missing in this circuit breaker variant. The breaker can be mounted by using a bus bar.

The 140U-H6C3-C30-MT circuit breaker is a switching device that interrupts an abnormal current flow or overload condition in a circuit. It protects an electrical system from being damaged. The breaker is equipped with fixed contacts, moving contacts, dielectric, and relays. A push-to-trip button is present on the front end of the breaker which lets the operators trip the circuit manually to test the breaker functionality. The 140U-H6C3-C30-MT circuit breaker can be operated in a temperature range between -25 and 60 degrees Celsius in a relatively humid environment with a maximum humidity level of 95% non-condensing relative humidity. The breaker is cooled by using the convection cooling method, and proper ventilation and airflow should be maintained at all times. It should also be protected from EMC noise.
