Fuse / Circut Breaker Selection - ABB EC Titanium Series Manual

4.3.1 Fuse / Circuit Breaker Selection
Suitable fuses to provide wiring protection of the input power cable should be installed in the incoming supply line,
according to the data in Table 4-2 Electrical Ratings. The fuses must comply with any local codes or regulations in place. In
general, type gG (IEC 60269) or UL type J fuses are suitable; however, in some cases type aR fuses may be required.
Check that the operating time of the fuse is below 0.5 seconds. The operating time depends on the fuse type, the supply
network impedance as well as the cross sectional area, material and length of the supply cable. In case the 0.5 seconds
operating time is exceeded with gG fuses, ultra-rapid (aR) fuses in most cases reduce the operating time to an acceptable
level.
Where allowed by local regulations, suitably dimensioned type B MCB circuit breakers of equivalent rating may be utilized in
place of fuses, providing that the clearing capacity is sufficient for the installation.
The maximum permissible short circuit current at the drive input power terminals as defined in IEC60439-1 is 5kA.
The rated fuse currents given in the table are the maximums for the mentioned fuse types. If smaller fuse ratings are use,
check that the fuse rms current rating is larger than the rated input amps shown in the rating tables in Chapter 2.

1. Cable sizes shown are the maximum possible that may be connected to the drive. Cables should be selected according
to local wiring codes or regulations applicable at the point of installation.
2. Refer to the UL Online Certification Directory for a list of UL Recognized products, File Number E226333.
3. The integral overload protection does not provide branch circuit protection. Branch circuit protection must be provided in
accordance with applicable local regulations and the National Electrical Code.
4. Fuse type: UL JDDZ Class J.
5. Where permitted, equivalent circuit breakers may be used.
