The Eaton Cutler-Hammer E501B18G3A reversing starter provides forward and reverse motor control in a compact B-frame 45mm package for 3-pole circuits, with a current rating range of 6.3 to 20 A. This unit is designed for industrial control panels and other installations where motor direction switching is required, delivering reliable start and reversal in a single assembly.

The E501B18G3A model uniquely identifies this unit within Eaton's Cutler-Hammer lineup, ensuring it meets the specifications for frame size and load range described in the product data. Verify that the motor load falls within the 6.3–20 A range and that the 45mm B-frame fits your enclosure.
