Fuse Tables; Branch Circuit Protection; Short-Circuit Protection - GE AF-600 FP Operating Instructions Manual

3.1.12 Fuses

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-circuited and
over-current protected according to national/international regulations.

Short-circuit protection:

The frequency converter must be protected against short-circuit to avoid electrical or fire hazard. GE recommends using the fuses mentioned below to protect
service personnel and equipment in case of an internal failure in the drive. The frequency converter provides full short-circuit protection in case of a short-circuit
3
on the motor output.
Over-current protection
Provide overload protection to avoid fire hazard due to overheating of the cables in the installation. Fuses or circuit breakers can be used to provide the over-
current protection in the installation. Over-current protection must always be carried out according to national regulations.

3.1.13 Fuse tables

380-480 V, frame sizes 4X, 5X and 6X
The fuses below are suitable for use on a circuit capable of delivering 100,000 Arms (symmetrical), 480V/600V depending on the drive voltage rating. With the
proper fusing the drive Short Circuit Current Rating (SCCR) is 100,000 Arms.
