140U-D6D3-C25

The 140U-D6D3-C25 from Allen Bradley operates as a molded case motor protection circuit breaker aimed at safeguarding motors in industrial settings. With a current rating that serves continuous loads of up to 25 Amps, it delivers reliable performance within its operational parameters. The three-pole configuration allows for versatile application in three-phase systems. This circuit breaker is rated for operational voltages reaching 600 Volts AC, making it well-suited for standard electrical distribution tasks.

It functions within a frequency range of 50 to 60 Hz, ensuring compatibility with common electrical systems. The interruption capacity at 400 to 415 V AC is rated at a breaking duty of 65 kA, while the service breaking capacity for the same voltage level is 50 kA. Further enhancing its operational capabilities, the unit can also handle similar breaking duties of 65 kA at a voltage of 525 V AC, while its service capacity drops to 25 kA.

For higher voltage applications, the breaker can interrupt up to 10 kA at 690 V AC during breaking duty and a service capacity of 6 kA, ensuring motor protection under various loads. Additionally, it maintains fault clearing capabilities of 65 kA at 240 V AC and also at 480Y/277 V AC for short-circuit protection. At higher voltage levels of 600Y/347 V AC, it can withstand faults rated at 25 kA. This versatile performance makes the 140U-D6D3-C25 an essential component for motor protection and circuit management.
