4 Available in CR305 Contactor forms. 5 Not available in NEMA Sizes 00 or 0. Use Size 1 contactor and modification. 6 24V coil not available on size 5 and 6.

1 Two indicating lights have each one wired in parallel with each operating coil. (Both red or red/amber or red/green.) Three lights have one wired in parallel with each operating coil with the third one wired through two normally closed auxiliary contacts. (Both red or red/amber, with green "OFF.") 2 Not available in NEMA Size 00. Use size 0 starter and modification. 3 The National Electrical Code, Article 450-3(B), requires primary fuses in most typical installations. Refer to the NEC, Article 450 prior to ordering control transformer without primary fuses to insure compliance. Control circuit fuse kits from page 1-136 may be used to provide primary fusing. Fuses must be sized to meet the requirements of the NEC according to the "Recommended Fuse" table. Control Circuit Fusing Per the NEC and UL508 Section 18.2 - Control Circuit Fuses must be used when the branch circuit protective device rating is too large to serve as protection for the control circuit . This depends on the control wire size and whether all control circuit wires are within the enclosure. See table below: Provide supplemental control circuit protection if control circuits with wires longer than 12 inches are connected to branch circuit protection exceeding the ratings below Control Maximum Branch Circuit Maximum Supplemental Circuit Protection Rating (Amperes) Control Circuit Wire Size Conductors Conductors Protection Rating (AWG) within Enclosure outside Enclosure (Amperes) 22 12 3 3 20 20 5 5 18 25 7 7 16 40 10 10 14 100 45 20 12 120 60 25

The factory must provide this protection, if the circuit provided by the factory requires the fuses. The factory will provide control circuit fuses in enclosed starters and contactors with pilot devices, control relays or other control components that are factory wired; when used with line voltage control; when the size listed below is being supplied. Non-combination starters (CR305, CR306, CR309, CR385, CR386) Size 4 and above Combination starters Size 0-3 with Mag-Break Protector Size 3 with: —Circuit Breaker greater than 100 amps, or —Fuse Clips greater than 100 amps, or Size 4 and above with any circuit breakers, circuit protector or fuse clips. Control Circuit fuses (Modification 9) must be added to the enclosed starter or contactor pricing. All CPTs will be supplied with primary fuses. CPTs without primary fuses are no longer available. When control circuit fuses are not factory supplied, customer provided wiring or branch circuit protection sizing to these contactors and starters may still require that the customer/installer add the fusing in the field. It will be the customer/installer’s responsibility to ensure code compliance under these conditions.
