Installation And Replacement Of Fuse Links - ABB SafeRing 36 Installation And Operating Instructions Manual

5.3 INSTALLATION AND REPLACEMENT OF FUSE LINKS

The F-module is equipped with a blown fuse indicator. If this
indicator changes colour from white to red, this means that at
least 1 fuse-link has blown. This will also automatically trip all
three phases of the switch-fuse disconnector. It also makes
operation of the switch-disconnector impossible before the
blown fuse-link(s) has been replaced.
Acc. to IEC 60282-1 it is advisable to replace all 3 fuse-links
even if only 1 or 2 has blown.
Fuse-links are replaced as shown in the sequence of illustra-
tions.
Switch-fuse combinations are supplied without fuse-links
installed.
