2 Requires oversized enclosure for NEMA sizes 0-2. Select proper NEMA size and enclosure type from step 1 (digits 1-7) table, page 1-55. 9 Relay/timer coil voltage is equivalent to CPT secondary voltage. Requires minimum 100 extra VA CPT option. 10 Maximum number of auxiliary contacts shall be reduced by 1.

General note: If selecting factory installed and wired operator devices (Push Buttons, 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.
