The above DC fuse recommendations are not required for UL conformity of the Mentor
MP drive. Any installations required to meet NEC and/or UL508a panel requirements,
must use recognized fuses that meet the requirements of the standard being applied.
The UL columns above indicate whether the recommended fuse is a UL recognized
component and not its conformance to either NEC or UL508a.
The use of the A100P series fuses is limited to applications with L/R time constants of
30 ms or less. DC fusing is only required on four quadrant (R) drives.
