Designed by Allen-Bradley, the 140U-D6D2-C10 circuit breaker is a 140 U MCB molded case circuit breaker. The 140U-D6D2-C10 circuit breaker is built with the D frame, while the rated current is 10 Amps. The Allen-Bradley circuit breaker features a magnetic trip rating of 15 to 20 Amps, while the unit has a breaking capacity of 100 kA. The interrupting rating is 100 kA and the pole configuration is 2 or 3 poles. The 140U-D6D2-C10 circuit breaker features a rated insulation voltage of 690 Volts IEC while the rated frequency is 50 to 60 Hertz. The Allen-Bradley molded case circuit breakers classified under the 140 U MCB series feature the 690 IEC/EN rating. These units are suitable for continuous operation at 100% of their rating only if they are used in cubicle spaces.

The 140U-D6D2-C10 circuit breaker features a mechanical lifespan of 100,000 hours, and the switching frequency lifespan is a maximum of 25 operations per hour. To ensure optimal functionality, the 140U-D6D2-C10 circuit breaker should be stored at an ambient temperature range of -40 to 80 degrees Celsius. The operation ambient temperature range is rated at -25 to 60 degrees Celsius. The Allen-Bradley 140 U MCB circuit breakers are meant for use in closed areas, where there are no hazardous operating conditions. Ensure that the 140U-D6D2-C10 circuit breaker is protected from dust or corrosive gases. The appropriate enclosure should be used to ensure the unit is always protected. The 140U-D6D2-C10 circuit breaker features shunt tripping, which is only operational if the 140U-D6D2-C10 circuit breaker is not set to undervoltage release. The breaker comes with a flex-cable operating mechanism that features a handle, a cable, and a bail mechanism. The circuit breaker features the phase barriers for providing additional phase clearances when special connections that extend past the circuit breaker housing are required.
