Description
Built for demanding industrial environments, the 140U-I6C3-C80 is an 80A, 3-pole molded case circuit breaker from Allen-Bradley. It utilizes fixed thermal and magnetic trip elements for essential LI protection. This unit-mount I-Frame breaker integrates seamlessly into Bulletin 140U systems. For future panel migrations, it is functionally replaced by the 140G-G6C3-C80, which uses a different frame size. Delivering 65kAIC at 480VAC, this HACR-rated breaker ensures superior current limiting.Specifications
