Installation
Fuses
Fuses (switches are supplied without fuses)
Install the fuses to the fuse base. Follow the instructions of the
fuse supplier. Standard delivery is with fuse bases suitable for
Class H, K and R fuses. Rejection members are available as
optional accessories for use with Class R fuses. The rejection
members for class R fuse clips prevent any other class of fuses
from being installed.
For 30 A, 60 A and 100 A safety switches are suitable also for
class J fuses. If class J fuses are used, the fuse base has to be
moved closer to the switch. The threaded holes to mount fuse
base for class R, J and T fuses are ready made in the enclosure.
Tighten fuse base screws to torque of 29 lbs.in (3.3 Nm).
In 60 A and 100 A safety switches also class T fuses can be
used. When using class T fuses the original fuse clips have to
be removed. The optional class T fuse clips are needed for 60
A. The optional bolt kit is needed for 100 A class T fuses.
