Trane TR170 - Fuses and Circuit Breakers

3.2.3 Fuses and Circuit Breakers
Branch circuit protection
To prevent
re
hazards, protect the branch circuits in an installation - switch gear, machines, and so on - against short
circuits and overcurrent. Follow national and local regulations.
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 100000 A
rms
(symmetrical), 480 V maximum.
UL/Non-UL compliance
To ensure compliance with UL or IEC 61800-5-1, use the circuit breakers or fuses listed in Table 3.5.
Circuit breakers must be designed for protection in a circuit capable of supplying a maximum of 10000 A
rms
(symmetrical),
480 V maximum.
NOTICE
In the event of malfunction, failure to follow the protection recommendation may result in damage to the frequency
converter.
