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 over-
current protected according to national/international
regulations.
Short-circuit Protection
The frequency converter must be protected against short-
circuit to avoid electrical or fire hazard. Trane recommends
using the fuses mentioned below to protect service
personnel and equipment in case of an internal failure in
the frequency converter. The frequency converter provides
full short-circuit protection in case of a short-circuit on the
motor output.
Over-current Protection
Provide overload protection to avoid fire hazard due to
overheating of the cables in the installation. The frequency
converter is equipped with an internal over-current
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 over-current protection in the installation.
Over-current protection must always be carried out
according to national regulations.
10.3.2 Fuse Selection
Trane 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 frequency converter.
The fuses below are suitable for use on a circuit capable of
delivering 100,000 Arms (symmetrical).
