8.10 Fuses and Circuit Breakers
8.10.1 Fuse Recommendations
Fuses ensure that possible damage to the drive is limited to damage inside the unit. Danfoss recommends fuses and/or circuit
breakers on the supply side as protection. For further information, see Application Note Fuses and Circuit Breakers.
N O T I C E
Use of fuses on the supply side is mandatory for IEC 60364 (CE) and NEC 2009 (UL) compliant installations.
Recommendations
gG type fuses.
Moeller type circuit breakers. For other circuit breaker types, ensure that the energy into the drive is equal to or lower than the
energy provided by Moeller types.
For further information, see Application Note Fuses and Circuit Breakers.
The recommended fuses in
8.10.2 CE Compliance, 8.10.3 UL Compliance (61800-5-1), and 8.10.4 UL Compliance (508C) are suitable
for use on a circuit capable of 100000 A
rms
(symmetrical), depending on the drive power and voltage rating. See the Electrical Data
section for the short-circuit current rating (SCCR) based on the specific power and voltage rating of the drive.
