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).
When UL/CSA Listed as manual, self-protected combination motor controllers, the 140M Motor Protection Circuit Breakers provide all the necessary NEC/CEC requirements for the protection and control of individual motor branch circuits without additional protective devices.
