About 140G-K3F3-D30

The Allen-Bradley 140G-K3F3-D30 molded case circuit breaker is a factory-assembled complete circuit breaker from the 140G K Frame circuit breaker series that is built for short-circuit, current, and thermal overload protection for the conductors and other equipment on the factory floor. The 140G-K3F3-D30 circuit breaker has adjustable magnetic and thermal trip values to accommodate a larger range of applications, and it features a very compact design with easy-to-install factory and field accessories. The 140G-K3F3-D30 circuit breaker belongs to the K Frame breaker series with a 400 Amps continuous current rating and a 600 Volts AC maximum operating voltage. It has a maximum breaking capacity rating of 35 kA at 480 Volts AC, and a rated voltage withstand of 8 kA. The 140G-K3F3-D30 circuit breaker has a mechanical lifespan of about 20,000 possible operations (without loading), and an electrical lifespan of up to 4000 operations at 415 Volts AC.



The 140G-K3F3-D30 circuit breaker has an 80% efficient continuous load rating at 40 degrees Celsius, and it gradually begins to de-rate at a temperature above this value. It has an adjustable thermal/magnetic trip unit with adjustable thermal trip ratings from 210 Amps to 300 Amps and magnetic trip ratings from 1500 Amps to 3000 Amps. The 140G-K3F3-D30 circuit breaker has a rotary switch handle of the make-break type that helps to open and close circuit breaker’s contact, and it also indicates whether the breaker is ON, OFF, or TRIPPED. It is capable of providing both fast-acting thermal and instantaneous magnetic trip actions for complete current and thermal overload protection. The 140G-K3F3-D30 circuit breaker has 3-pole wiring and it is suitable for 3-phase applications. It has bolt-on line and load terminals as standard features and it is supplied with 1-meter-long pig-tail wiring for terminating optional internal accessories. The 140G-K3F3-D30 circuit breaker is CCC, CSA, UL, and CE certified, and it weighs approximately 7.17 pounds.
