Allen-Bradley Bulletin 100-E IEC universal contactors

Traditionally, contactors have been used to switch electrical loads in numerous applications, such as motors, fans and pumps. However, large contactors are increasingly used in applications to isolate or bypass these loads and for switching of resistive loads. To accommodate this change, the Allen-Bradley Bulletin 100-E IEC contactors feature a universal coil, which offers operators more flexibility when controlling with multiple voltages.

The contactors can be controlled with 40 to 50 different voltages, ranging from 24 to 500 V, with only four different coil options.

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, according to Rockwell Automation.

The contactors replace the Allen-Bradley Bulletin 100-D IEC contactors and increase the available current range to 116–2650 A. They have a 25% smaller footprint than previous product lines.
