4.3 Fuses

4.3.1 Introduction

Use fuses and/or circuit breakers on the supply side to
protect service personnel and equipment from injuries and
damage in case of component breakdown inside the
frequency converter (first fault).

Branch circuit protection

All branch circuits in an installation, switch gear, machines
etc. must be protected against short circuit and
overcurrent according to national/international regulations.

NOTICE

The recommendations do not cover branch circuit
protection for UL.

lists the recommended fuses that have been

tested.

If fuses are selected according to recommendations,
possible damages can be limited to inside the frequency
converter.

WARNING

Malfunction or failing to follow the recommendations
may result in personal risk and damage to the frequency
converter and other equipment.

4.3.2 CE Compliance

NOTICE

Using fuses or circuit breakers is mandatory to ensure
compliance with IEC 60364 for CE.

Danfoss recommends using the fuses in

on a

circuit capable of delivering 100000 A

rms

(symmetrical),

380–480 V depending on the frequency converter voltage
rating. With the proper fusing, the frequency converter
short circuit current rating (SCCR) is 100000 A

rms
