Installation
3.2.4 Fuses and Circuit Breakers
Branch circuit protection
To prevent fire hazards, protect the branch circuits in an
installation - switch gear, machines, and so on - against
short circuits and overcurrent. Follow national and local
regulations.
Short-circuit protection
Danfoss recommends using the fuses and circuit breakers
listed in Table 3.7 to protect service personnel or other
equipment in case of an internal failure in the unit or a
short circuit on the DC link. The frequency converter
provides full short-circuit protection in case of a short
circuit on the motor.
Overcurrent protection
Provide overload protection to avoid overheating of the
cables in the installation. Overcurrent protection must
always be carried out according to local and national

UL/Non-UL compliance
To ensure compliance with UL or IEC 61800-5-1, use the
circuit breakers or fuses listed in Table 3.7.
Circuit breakers must be designed for protection in a
circuit capable of supplying a maximum of 10000 A
(symmetrical), 480 V maximum.
NOTICE
In the event of malfunction, failure to follow the
protection recommendation may result in damage to the
frequency converter.
