We took a look at the power budget for the DT/DM and all of the subsystems in the machine and recognized that the main breaker was over-specified. As of 4/2018 the main circuit breaker assembly has been changed:
- DT/DM 240V changed from 80A to 40A
- DT/DM 480V changed from 40A to 20A
The Haascnc.com website shows the updated electrical specifications.
If you are installing a machine with a large breaker and the customer has already prepared power based on the newly revised specifications then the machine can be installed as-is and you can order the smaller breaker for installation at a later date.
