MILWAUKEE, WI, USA, Mar 27, 2018 – Global machine and equipment builders designing panels for global markets need to select the right components to meet numerous international standards as well as address changing energy-efficiency guidelines. To address these needs, Rockwell Automation has released the Allen-Bradley Bulletin 300 NEMA contactors and Bulletin 100-E IEC contactors to help machine builders design smaller, more energy-efficient panels.




Traditionally, contactors regulated electrical loads for large applications, such as large motors, fans and pumps. However, contactors are increasingly used in more robust applications to regulate bypass and resistive loads. To accommodate this change, new lines of contactors feature a universal coil, which offers operators more flexibility when controlling multiple voltages. The new contactors also provide protection from power overload, as well as protection for circuit breakers and motors.

“Typically, with contactors, you need to specify what voltage you want to control,” said Tom Peterson, global product marketing manager, IEC Contactors, Rockwell Automation. “With the new lines, operators can control 40 to 50 different voltages ranging from 24 to 500 volts.”

Previous options were available in multiple voltages and often required an AC or DC coil to control applications. With the introduction of the universal coil, operators can more easily control voltage on multiple applications with fewer parts.

“These coils are also much more energy efficient,” said Peterson. “With the new device, operators can operate the same applications with a smaller power supply.”

In addition to the universal coil, the new contactors are significantly smaller than previous product lines. The Bulletin 100-E IEC contactors have a 25 percent smaller footprint while the Bulletin 300 NEMA contactors are 45 percent smaller than previous product lines.

“The new contactors are smaller in size than previous lines,” said Tony Hart, global product marketing manager, NEMA Contactors, Rockwell Automation. “A more compact contactor requires a smaller panel and a smaller enclosure.”

The new contactors replace the Allen-Bradley Bulletin 100D IEC and NEMA contactors. While the previous line featured contactors for applications above 100 amps, the new contactors are designed for applications 300 amps or higher.
