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 , D, and F FramesThe 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.

3 SeeApplication 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 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). Type E and Type F Combination Motor ControllersMost of the Motor Protection Circuit breakers are UL Listed as a manual Type E self-protected combination Motor controller. Although there are many tests involved, one of the critical tests a self-protected combination Motor controller must pass, is to perform 6000 electrical operations and an additional 4000 mechanical operations after a short definition, a Ty p e F combination Motor controller consists of a Type E manual self protected combination Motor controller and a magnetic or solid-state Motor controller (such as a Bulletin 100-C contactor or an SMC).

4 As with a manual Type E self-protected combination Motor controller, additional short- Circuit Protection is not required for the individual Motor combination of a Bulletin 140M manual self protected combination Motor controller and 100-C contactor can be listed as a Type E self-protected combination Motor controller. In this case, both the 140M and 100-C must pass the additional 6000 electrical and 4000 mechanical operational test. In some cases, this may require over sizing of the Bulletin 140M MPCB or the 100-C contactor to achieve weld free performance and meet the additional life Compliance and CertificationsStandards ComplianceCertificationsIEC/EN60947-1,-2 ,-4-1,-5-1CE MarkedIEC/EN60204-1 CCCCSA, CertifiedUL508cULus Listed (File No. E54612, NLRV(7); E205542, NKJH(7); E197878, DIVQ(7);)ATEX4 Rockwell Automation Publication 140M-TD002G-EN-P - January 2018 Motor Protection Circuit Breaker and Motor Circuit Protector SpecificationsC-FrameD-FrameF-FrameMax.

Group installation has been successfully used for many years in the and Canada. It allows two or motors or one or more motors and other loads to be connected to the same . The most restrictive part of the conditions specified for Group Installation is the requirement for the Protection of the conductors for each Motor Circuit . In the NEC for 2002, a new rule for the conductor sizing was added for devices that are listed and marked Suitable for use as Tap Conductor Protection .

Additional short- Circuit Protection is not required for the Protection of the individual Motor circuits, leaving only the requirement for Protection of the feeder Circuit conductors by an upstream protective device.
