10.3 Fuse Tables

10.3.1 Protection

Branch Circuit Protection
In order to protect the installation against electrical and
fire hazard, all branch circuits in an installation, switch
gear, machines, etc., must be short-circuited and
overcurrent protected according to national/international
regulations.

Short-circuit Protection
The adjustable frequency drive must be protected against
short-circuit to avoid electrical or fire hazard. Danfoss
recommends using the fuses mentioned below to protect
service personnel and equipment in case of an internal
failure in the adjustable frequency drive. The adjustable
frequency drive provides full short-circuit protection in
case of a short-circuit on the motor output.

Overcurrent Protection:
Provide overload protection to avoid fire hazard due to
overheating of the cables in the installation. The adjustable
frequency drive is equipped with internal overcurrent
protection that can be used for upstream overload

protection (UL applications excluded). See

4-18 Current

Limit

. Moreover, fuses or circuit breakers can be used to

provide the overcurrent protection in the installation.
Overcurrent protection must always be carried out
according to national regulations.

10.3.2 Fuse Selection

Danfoss recommends using the following fuses which will
ensure compliance with EN50178. In case of malfunction,
not following the recommendation may result in
unnecessary damage to the adjustable frequency drive.

The fuses below are suitable for use on a circuit capable of
delivering 100,000 Arms (symmetrical).
