140U-D6D3-C30

The 140U-D6D3-C30 circuit breaker is an Allen-Bradley/Rockwell Automation circuit breaker that requires minimum panel space. The footprint of the device is up to 50% smaller than traditional units with similar purposes. This UL489 listed circuit breaker offers a very high interrupting rating and advanced current limiting capabilities. The 140U-D6D3-C30 circuit breaker is designed for applications such as high-intensity discharge, distribution panels, transformers, and power supply applications. The 140U-D series of molded case circuit breakers offer variants with 2 and 3 poles, along with a range of accessories that include load terminal covers, compact busbar feeder terminals with a maximum continuous current of 64 Amps, an eco connection module for a DIN rail, and a flexible wire module.

The 140U-D6D3-C30 3-pole circuit breaker has a rated current of 30 Amps and a 15 to 20 x In magnetic trip [Amp] Lm. Generally, the 140U-D breaker series has a current range of 0 to 30 Amps. The breaking capacity of the unit is 65 (ICU) kiloAmps for 400 to 415 Volts and 525 Volts. The breaking capacity for 690 Volts is 10 (ICU) kiloAmps. In addition to that, the interrupting capacity at 60 Hertz is 65 kiloAmps for 240 Volts and 480Y/277 Volts. The interrupting capacity for a voltage of 600Y/347 Volts is 25 kiloAmps. The 140U-D6D3-C30 breaker is a high-quality protection device that comes with a frame size of D and rotary operators. This thermal-magnetic device also features internal control modules that are typically installed directly in the field. Also, the 140U-D6D3-C30 circuit breaker is made in compliance with the CSA C22.2 (No.5), IEC 60947-2, and CE regulations. The ambient operating temperature range should be from -25 degrees Celsius to 60 degrees Celsius (-13 degrees Fahrenheit to 140 degrees Fahrenheit). This device is HACR rated and it has a rated insulation voltage of 690 Volts according to the IEC/EN standards, and it has one of 600 Volts according to the UL/CSA standards.
