Factoryinstalled internal accessories make installation and wiring easy. General Information Table of Contents Product Selection — Motor Protection Circuit Breakers.......... 2-8 Approximate Dimensions................... 2-51 Current Range 0.1…630 A UL Listed for Motor Loads − Short Circuit Protection − Overload Protection Visible Trip Indication High Current Limiting High Switching Capacity Certifications Standards Compliance Motor Protection Circuit Breakers may provide the following protective and control functions. Disconnect for Motor Branch Circuit Branch-Circuit, Short-Circuit Protection (Magnetic Protection) Overload Protection (Thermal Protection) Switching (Manual) In North America, electrical codes require that an individual Motor Branch Circuit be protected by a UL/CSA Listed Fuse, Circuit Breaker or Self-Protected Combination Motor Controller. 140M-C, D and F Frames: The 140M-C, D and F frame Motor Protection Circuit Breakers may have 2 cULus 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, 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, these devices must be applied per the appropriate rules which require the use of an upstream Branch-Circuit, Short-Circuit Protective Device (BCPD). See the table on page 2-18 for the specific ratings of each Motor Protection Circuit Breaker. 140-CMN Frame: The 140-CMN frame Motor Protection Circuit Breakers are UL Listed/CSA Certified as Manual Motor Controllers (with optional approvals for Motor Disconnect and Group Installation). In NEC/CEC Group Installations, these devices must be applied per the appropriate rules which require the use of an upstream Branch-Circuit, Short-Circuit Protective Device (BCPD). See the table on page 2-18 for the specific ratings of each Motor Protection Circuit Breaker. 140M-I, J and L Frames: The 140M-I, J and L frame Motor Protection Circuit Breakers are cULus Listed as Circuit Breakers as shown in the table on page 2-9. In these cases, 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. For further details on the proper application of Motor Protection Circuit Breakers, please see the diagrams on the following pages. IEC/EN 60947-1, -2, -4-1, -5-1
