These breakers come in two versions — one with magnetic trip element for short-circuit protection and the other with thermal and magnetic trip elements for overload and short-circuit protection. They can be used by themselves as manual motor controllers, and they also work well with Series 300 contactors in group motor installations. An ON/OFF manual operator makes it easy to isolate motor circuits without disconnecting all of a control panel's circuits. They have visual trip indicators for easy spotting of tripped circuits, and a test function for verifying device performance and proper control circuit operation. They have a modular design and come with accessories such as auxiliary contacts, shunt and undervoltage release modules, and wiring accessories. They come in universal ratings and markings: A, kW and HP ratings, plus applicable third-party certification markings.
