1.3.6 Fuses and Circuit Breakers

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-circuit and overcurrent protected according to national and local regulations.
Short circuit protection
Danfoss recommends using the fuses and circuit breakers listed in Table 1.19 and to protect service personnel or other
equipment in case of an internal failure in the unit or short-circuit on 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 regulations. Circuit breakers and fuses must be designed for protection in a
circuit capable of supplying a maximum of 100,000 A
UL/Non UL compliance
Use the circuit breakers or fuses listed in Table 1.19, to ensure compliance with UL or IEC 61800-5-1.
Circuit breakers must be designed for protection in a circuit capable of supplying a maximum of 10,000 Arms (symmetrical),
480 V maximum.
In the event of malfunction, failure to follow the protection recommendation may result in damage to the frequency
converter.
