AB rockwell NEMA and IEC contactor application skills
Allen-bradley Bulletin 300 NEMA contactor and Bulletin 100-e IEC contactor are designed to help machine manufacturers design smaller, energy efficient control cabinets.
In the past, contactors were commonly used to switch electrical loads.Load types include large motors, fans and pumps.Today, larger contactors are increasingly used to isolate and bypass these loads and to shut off resistance loads.In order to adapt to this change, the *** series contactors adopt a universal coil, which helps the operator to conduct multi-voltage control more flexibly.
"With contactors, you usually need to determine the control voltage," said Tom Peterson, global product marketing manager for rockwell automation IEC contactors.
Although previous products also supported multi-voltage control, it was common to use ac or dc coils for application control.With the introduction of universal coils, operators can control multiple application voltages more easily with fewer product models.
"In addition, universal coils can significantly improve energy efficiency," Peterson said.
In addition to the introduction of the universal coil, the new contactor also has a size advantage over the previous series.Compared with previous products, the Bulletin 100-e IEC contactor can save 25% of the space, while the Bulletin 300 NEMA contactor can even save 45% of the space.
"The new contactor is smaller than previous product lines," said rockwell automation NEMA contactor global product marketing manager. "the more compact size allows the new contactor product to be installed in a smaller control cabinet."
