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: If selecting factory installed and wired operator devices ((pushbuttons, selector switches and/or pilot lights), control circuit fusing, a control power transformer or 24 V/120 V separate sourced control is required, regardless of protective device rating.
