5 Relay/timer coil voltage is equivalent to CPT secondary voltage. Requires minimum 100 extra VA CPT option. 6 Maximum number of auxiliary contacts shall be reduced by 1.

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.
