The Bulletin 140M Motor Protection Circuit Breakers provide short circuit and overload protection for individual motor loads. Factory-installed internal accessories make installation and wiring easy. The 140M-C, D and F frame Motor Protection Circuit Breakers may have 2 UL/CSA Listings – as Manual, Self-Protected Combination Motor Controllers and as Manual Motor Controllers (with optional approvals for Motor Disconnect and Group Installation). When UL/CSA listed as Manual, Self-Protected Combination Motor Controllers as shown in Table on , the 140M Motor Protection Circuit Breakers provide all of the necessary NEC/CEC requirements for the protection and control of individual Motor Branch Circuits without additional protective devices. At some higher voltages and currents (particularly at 600V), a few of the 140M-C, D and F frame devices are only UL/CSA Listed as Manual Motor Controllers (with optional approvals for Motor Disconnect and Group Installation). In NEC/CEC Group Installations.

The Bulletin 140M Motor Protection Circuit Breaker line has been expanded to provide motor protection up to 300 Hp at 600V. This expanded line of Motor Protection Circuit Breakers provides all necessary functions to meet global requirements for motor branch circuit protection, including: Disconnecting means. Branch-circuit short-circuit protection
Overload protection. Bulletin 140M Motor Protection Circuit Breakers can be used in combination with Allen-Bradley Bulletin 100 Contactors to create compact and reliable two-component combination starters. Series 8527 motor protection circuits-breakers are used where high short circuit currents are to be controlled and to protect both Ex e- and Ex d-motors. This switches are suitable to protect the installation basically without a back-up fuse. The breakers are actuated by a rotatable grip, which also gives unambiguous switch position identification. these devices must be applied per the appropriate rules which require the use of an upstream Branch-Circuit, Short-Circuit Protective Device (BCPD). See Table on for the specific ratings of each Motor Protection Circuit Breaker.
