NOTES
1. For negative logic remote on/off, add the suffix “R” to the part number (Ex: CMRJW48S12-1000R).
2. To add remote option and pin add the suffix “RC” to the part number (Ex: CMRJW48S12-1000RC).
3. Remote On/Off models do not have UL1950 approval.
4. Chassis Mount Options: No suffix for open frame, “U” suffix for U Channel, and “E” suffix for Enclosed type.
*Due to advances in technology, specifications subject to change without notice.
