Here is my second piece of news from the foundation level of the enterprise pyramid. I lien’t think I’d write about motor control again. This news from Rockwell Automation announces a complete revision to its Allen-Bradley Branch Motor Control & Protection Solutions.

The recent overhaul of its motor control components within its Branch Motor Control & Protection Solution was brought on by the need for updating full systems where components are used to turn on and off motors of all sizes while helping protect the motors from overloading during operation. Basic across-the-line motor starters remain ubiquitous in industrial applications despite the proliferation of solid-state motor starting technologies. These components comprise motor starting contactors, motor-specific circuit breakers and motor-overload relays, where depending on the application, the motor overload functionality can be incorporated in the circuit breaker or applied as a separate component.

One of the significant advantages of the system is the availability of the wide-range, energy-saving coils for Bulletin 100-E architecture-class contactors. These coils use much less energy in operation, and cover AC and DC control circuits from 24 to 240 volts, making selection much easier. Safety versions of the contactors are available, as well as NEMA-rated options. Bulletin E100 Electronic Overload Relays are now also compatible with Bulletin 100-E and 100-C Contactors to enhance systems.

The recently launched Bulletin 140MT line of Motor Protection Circuit Breakers and Motor Circuit Protectors provides higher short-circuit ratings than the products they replace. And the range of E100/200/300 electronic overload relays includes options for EtherNet/IP integration that enables comprehensive diagnostics and Logix integration.
