3.5 Fuses

3.5.1 Branch Circuit Protection

To prevent re hazards, protect the branch circuits in an installation, switch gear, machines, and so on, against short circuits and

overcurrent. Follow national and local regulations.

3.5.2 Short-circuit Protection

Use the Danfoss recommended fuses to protect service personnel or other equipment if there is an internal failure in the unit or

short circuit on DC-link. If there is a short circuit on the motor or brake output, the drive provides full short-circuit protection.

3.5.3 Overcurrent Protection

To avoid overheating of the cables in the installation, provide overload protection. Always carry out overcurrent protection accord-

ing to national regulations. Fuses must be designed for protection in a circuit capable of supplying a maximum of 100000 A

rms

(symmetrical), 480 V maximum.

3.5.4 Non-UL Compliance

If UL/cUL is not to be complied with, use the fuses mentioned in this chapter, which ensure compliance with EN50178/IEC61800-5-1.

If there is a malfunction, not following the fuse recommendation may result in damage to the drive and the installation.
