5.9 Installing Upstream Fuses
5.9.1 Upstream Fuse Considerations
Factory fuse options like a fusible disconnector or MCCB protect the busbars and circuits within the drive. To protect the cables, an
installer should use separate F1 fuses for upstream protection.
• Danfoss recommends the fuse type gG (IEC 60269-1) for the mains fuses. Use only fuses with a sufficient voltage rating according
to the mains voltage. Do not use larger fuses than what is recommended. These fuses are selected for short-circuit protection only.
• Operation time of the fuse must be less than 0.4 s. The operation time must also agree with the fuse type and the impedance of the
supply circuit.
• The recommended mains cable and fuse sizes are valid up to a cable length of 100 m, with mains having a short-circuit current of
20 kA. Recommended cable sizes are shown in the Electrical Data section.
• Danfoss recommends the use of FC1 fuses to meet short-circuit protection for any enclosed drives supplied with only the non-
fusible disconnect, a non-fusible disconnect and contactor, or a contactor only option.
