TPB fuses are not meant as fixing isolators. Excessive push,
pull and tensional forces due to misalignments between fuse
and bus bars, which might occur like in the example shown
below, should be avoided. If possible the fuse installation
should be made starting with a fixed input busbar. The fuse
should then be mounted to the input busbar, followed by the
output busbar. Finally, the output busbar should be rigidly
fixed within the system equipment.

TPB fuses are electro-mechanical devices. Their function is
very much dependent of the quality of the contact between
the fuse and the connecting bus bars. A poor thermal con-
nection can result in overheating of the fuse and reduced life-
time. The number one rule is therefore to observe the right
tightening torque when mounting the fuse. See Table A.

Bussmann recommends a calibrated torque wrench with a
tolerance of max. ±4%.
Fus e s with flus h e nd c onta c ts
For all types of flush end fuses Bussmann recommends
(screw in) studs. The studs must be tightened carefully apply-
ing a torque of 5-8Nm (3.7 -5.9 lbf-ft). As a general rule the
tightening torque for the nuts relates to the dimension of the
threaded hole in the fuse contact. See Table A for the recom-
mended nut tightening torques.
