7. Power Ratings (UL508 - CAN/CSA C22.2 No. 14)
| Voltage | 3x240V HP | 3x480V HP | 3x600V HP |
|---|---|---|---|
| Size 0 (T12, T20, TF12, TF16, TF25) | 2 to 7.5 HP | 5 to 12 HP | 5 to 15 HP |
| Size 1 (T16, T25, T32, T40) | 5 to 15 HP | 10 to 25 HP | 10 to 25 HP |
| Size 2 (T50, T63, T80, T100, T125, T175) | 20 to 30 HP | 40 to 60 HP | 40 to 50 HP |
8. Dimensions and Mechanical Data
Detailed dimensional drawings and measurements are provided, including panel cutouts, mounting hole spacing, and shaft extension lengths (L1-L4). Dimensions vary by series and pole count to support precise installation.
9. Recommendations and Notes
- Consult manufacturer for mechanical durability values beyond standard ratings and for higher current ratings (400A to 800A).
- Specify shaft extension lengths when ordering base mounting switches.
- Some ratings depend on mounting configuration and use of phase barriers.
- Downloadable documents available for accessory details and general series information.
- Special mounting or wiring conditions may require manufacturer consultation.
Summary
The CAM switches O-I series provide a versatile and robust solution for industrial control applications, offering a broad range of sizes, electrical ratings, and mounting options. Compliance with international standards ensures reliable performance, while detailed mechanical and electrical data facilitate proper selection and installation.
