Product FAQs
5 answersHow do I decode the 140U-I6C3-C15 catalog number?
"140U" is the Allen Bradley molded case circuit breaker series. "I" indicates the I-Frame size. "6" specifies the 65kA at 480VAC interrupting rating. "C3" denotes a 3-pole configuration, and "C15" represents the 15A continuous current rating.
What does the "LI" trip function code mean for this breaker?
The "LI" code indicates that the thermal-magnetic trip unit provides Long-Time (L) overload protection and Instantaneous (I) short-circuit protection. Both the thermal and magnetic trip points are fixed on this model.
Where is the 140U-I6C3-C15 typically installed?
This unit-mount, bolt-on breaker is designed for use in industrial control panels and motor control centers requiring reliable branch circuit protection.
Is the 140U-I6C3-C15 part of an active or legacy product line?
The 140U series is a legacy product line. Rockwell Automation has introduced newer series, such as the 140G and 140UT, as modernization paths for these older molded case circuit breakers.
Does this breaker provide adjustable trip settings?
No, the 140U-I6C3-C15 features a fixed thermal and fixed magnetic trip unit. If your application requires adjustable overload or short-circuit settings, a different frame or trip unit type is required.
