A product of Allen-Bradley, the 140U-D6D2-B80 circuit breaker is a molded case circuit breaker. The 140U-D6D2-B80 circuit breaker is classified under the 140U MCB series, and it comes with the UL 489 certification, which means it is suitable for use globally. The 140U MCB series comprises circuit breakers that are commonly used in feeder circuits, control circuits, heating, and air conditioning, and in applications that feature high-intensity discharge. The 140U-D6D2-B80 circuit breaker features a small design size compared to conventional circuit breakers. The circuit breaker delivers a 100% rating of up to 15 Amps, and it is suitable for back feeding at 240 Volts and 480Y/277 Volts. The Allen-Bradley 140U MCB series features field-installed and factory-installed accessories. The 140U-D6D2-B80 circuit breaker is easy to monitor to ensure optimal functionality and quick troubleshooting. This is delivered through the auxiliary contact (AX), which electrically indicates the ON/OFF status of the circuit breaker. The units also feature the alarm contact (AL) that indicates when the unit is tripped.

The Allen-Bradley 140U-D6D2-B80 circuit breaker features a shunt trip for providing the remote tripping of the circuit breaker undervoltage trip, which is not available when the shunt trip is in use. The Allen-Bradley 140 U MCB units are designed with the undervoltage release  (UVT) feature. The UVT ensures automatic tripping whenever the circuit breaker detects a voltage that is below the preset level. When the undervoltage release trip is activated, the shunt trip is automatically deactivated. The 140U-D6D2-B80 circuit breaker features the terminal shields and it comes with a Flex-Cable operating mechanism. This includes the handle, the cable, and the operating and the bail mechanism. The Allen-Bradley 140U-D6D2-B80 circuit breaker features a high-performance level and it is ideal for applications requiring high protection levels.
