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.
Researchers working with additive manufacturing have said multimaterial techniques will allow industry to fabricate materials with combinations of density, strength, and thermal expansion that do not exist [yet].
The term "multiphysics" is used to describe the simulation of multiple types of physics and their influence on one another -- for example, the investigation of the behavior of a chemical in liquid form will involve both chemistry and fluid dynamics.
