General note: On NEMA size 3 and 4 starters, if selecting factory installed and wired operator devices (pushbuttons, selector switches and/or pilot lights), then control circuit fusing, a control power transformer or 120 V separate sourced control is required when the protective device is rated greater than 100 amps.

Please reference the NEMA full voltage power devices catalog for additional technical data, selection and installation guides, and dimensional drawings.
