The molded case circuit breaker known as the 140U-D6D3-C10 circuit breaker is available through the 1400U-D product series by Allen-Bradley/Rockwell Automation. This thermal-magnetic circuit breaker has a D frame and 3 poles. When used in cubicle space, this HACR rated circuit breaker is built for continuous operation at 100% of its rating at up to 15 Amps of current. The required cubicle space for the breaker is 250 x 175 x 150 millimeters (10 x 7 x 6 inches). Generally, the current rating of the 140U-D6D3-C10 circuit breaker is 0.5 to 30 Amps. The unit is intended for use at an ambient temperature range of -25 to 60 degrees Celsius (-13 to 140 degrees Fahrenheit) and it can be stored at a temperature range of -40 to 80 degrees Celsius (-40 to 176 degrees Fahrenheit). The IP2X protected circuit breaker has a shock resistance rating of 30 G at 11 milliseconds and 18 G of vibration tolerance. The 140U-D6D3-C10 breaker includes protection from short circuits but it does not include phase-loss protection. The 140U-D6D3-C10 circuit breaker features rotary operators and internal control modules that can be installed in the field. The unit is CE listed and made to meet standards such as the UL489, IEC/EN 60947-1, and CSA C22.2 standards. The circuit breaker has features like a high interrupting rating of 65 kiloAmps and current limiting. In comparison with standard miniature circuit breakers, this type of breaker has up to a 6 times higher interrupting rating. Also, it offers reduced installation costs and less wiring problems than other circuit breakers due to the simple and clever design of parts such as the feeder blocks and compact busbars. The 140U-D6D3-C10 circuit breaker is suitable for back feeding at an input voltage of 240 Volts and at 480Y/277 Volts. This kind of circuit breaker is intended for applications that include feeder circuits (branch circuit protection, transformers, heaters, and small cabinets applications), control circuits (control transformers and power supplies), and high-intensity discharge.
The 140U-D6D3-C10 is a Molded Case Circuit Breaker by Allen-Bradley. This circuit breaker is a 3-Pole, Frame D electrical device that is primarily used for branch circuit protections in a variety of industrial applications for implementing Branch circuit protection, Power distribution protection, and isolation device.
The 140U-D6D3-C10 has a rated insulation voltage of 690 Volts per IEC / EN standards and 600 Volts per UL and CSA. This breaker can be operated continuously at 100 percent of rating provided that the cubicle space is 250 x 175 x 150 millimeters (10 x 7 x 6 inches).
The 140U-D6D3-C10 has a mechanical lifespan of 100,000 operations and 10,000 Ie, maximum operations while the breakers maximum switching frequency per hour is 25. It has an IP protection class of IP2X when wired and offers protection features such as Magnetic short circuit protection of 15…20 x In which is a fixed setting. This breaker may also be used as a main disconnect switch; however, accessories may be needed to operate along the 140U-D6D3-C10.
Being a D-Frame breaker, the 140U-D6D3-C10 is provided with rotary operator and field installed internal control modules. It has a breaking capacity of 100 Icu, 65 Ics @ 400-415 Volts; 65 Icu and 65 Ics @ 525 Volts; 10 Icu and 6 Ics @ 690 Volts. The 140U-D6D3-C10 interrupt capacity is 100 kA @240 Volts / 480Y / 277 and 50 kA @ 600Y / 374 Volts.
The 140U-D6D3-C10 carries certifications from CE; cULus listed Circuit Breaker, File No. E334037 and E33916 (accessories) and complies to a variety of standards such as UL489; CSA C22.2 No. 5; IEC / EN 60947-1, -2.
