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).
Description:
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 SelfProtected
Combination Motor Controller.
140M-C, D, and F Frames
The 140M-C, D, and F frame Motor Protection Circuit Breakers may have two cULus Listings - as Manual, Self-Protected Combination Motor
Controllers and as Manual Motor Controllers (with optional approvals for Motor Disconnect and Group Installation). Cat. No. 140M-D8V* can
also be applied at the output of a variable frequency drive (VFD) in multi-motor applications. See Application Conditions (140M-D8V) on
page 41 for more information.
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.
