General Information: • Telpower® BLUE™ label fuses are specifically designed for dc power distribution systems. • Minimum I2t short-circuit let-through levels. • Current-limiting capability. • Complete system coordination capability. Mounting Alignment 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.

Their function is very much dependent of the quality of the contact between the fuse and the connecting bus bars. A poor thermal connection can result in overheating of the fuse and reduced lifetime. The number one rule is therefore to observe the right tightening torque when mounting the fuse. See Table A. Fuses with flush end contacts For all types of flush end fuses Bussmann recommends (screw in) studs. The studs must be tightened carefully applying 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 recommended nut tightening torques.
