Bulletin 140G MCCB

The Allen-Bradley Bulletin 140G is a family of molded case circuit breakers (MCCBs) spanning multiple frame sizes and interrupting ratings for industrial power distribution and branch-circuit protection. The catalog number follows a structured format: the frame-size letter (G, H, J, M, and others) identifies the ampere frame rating, the pole count and trip-unit code follow, and dash suffixes encode the ampere trip setting, interrupting capacity, and accessory options — for example, 140G-G3C3-C30-MT identifies a 125 A G-frame, 3-pole, fixed thermal-magnetic trip breaker at 35 kA/480 V with a specific terminal configuration, while 140G-M5F3-D80-SJ-AA identifies an 800 A M-frame with adjustable thermal and adjustable magnetic trip. Current-limiting variants (HC prefix, e.g., 140G-HC6C3-C50-KJ) deliver elevated 65 kA interrupting ratings at 480 V. Accessories such as rotary operators (140G-M-RVM12R) and flexible cable mechanisms (140G-M-FCS06) extend mounting and switching flexibility across the M-frame line. With more than 1,600 catalog numbers, this family covers a broad range of frame sizes, trip-unit styles, and accessory configurations; consult the Bulletin 140G MCCB Technical Data for full selection guidance.
