The Allen-Bradley 140MG-H8P-B30 Motor Protector Circuit Breaker is a high break motor protector circuit breaker that is designed to provide short-circuit protection. It belongs to the H Frame circuit protector series, and it features high switching capacity and high current limiting range to allow it to accommodate a wide range of applications. The 140MG-H8P-B30 Circuit Breaker comes with visible trip indication and a lever-type toggle switch for control. Generally, the 140MG-H8P-B30 Circuit Breaker and every other Bulletin 140MG circuit breaker can be used as the main disconnect device in a branch circuit, as switching devices in a control panel, as branch-circuits, and as short-circuit protection devices. Since the Bulletin 140MG motor protector circuit breakers provide only short-circuit protection and not thermal overload protection, they are only UL/CSA recognized rather than listed as standard circuit breakers, and they are also CE, CSA, and CCC certified.

The 140MG-H8P-B30 Circuit Breaker belongs to the H-frame motor protector circuit breaker series, and it has a current rating of 3 Amps. This device has a breaking capacity of 100 Kilo-Amps at 415 Volts AC and a rated operating power of 0.5 Horsepower at 230 Volts AC and of 1.5 Horsepower at 460 Volts AC (3-phase). The 140MG-H8P-B30 Circuit Breaker is designed for applications with an operating voltage range between 200 and 575 Volts AC (3-phase), and it only has an adjustable magnetic trip unit as its protection unit. The magnetic trip unit provides an adjustable trip rating of up to 10 times the Full Load Amps (FLA) rating, and by using a CAM controlled mechanism, the operators can adjust the trip settings from 12 to 33 Amps to accommodate a wider range of applications. The 140MG-H8P-B30 Circuit Breaker has a 3-pole design (it can be wired for both single-phase and three-phase applications), and it has an end-cap bolt-on terminal as a standard terminal.
