RECTICUR-type ultra-rapid fuses are used to protect semiconductor components in power converters.
D fuse links are designed for rated voltages of 500 V AC with rated currents extending from 2 to 100A.
Technical Notes
RECTICUR fuse links are equipped with fuse elements made of fine silver. The number and shape of
their reductions in cross-section ensure satisfactory disconnection and optimum operating characteris-
tics.
The design of the fuse element determines the characteristic curve and the remaining electrical pro-
perties of this fuse link.
Fuse links with gR characteristic provide total protection against overloading and against short-circuit
currents.
Breaking Capacity
The switching reliability of RECTICUR semiconductor fuses has been verified in numerous tests exten-
ding up to the highest short-circuit currents. Rated braking capacity is 100 kA (RMS) for D-fuse links.
RECTICUR D Fuse bases
RECTICUR D fuse links can be fitted in all normal fuse-bases of the D system, using all usual accessories
such as screw-cap and adaptor sleeve.
1 - This indicates the following maximum loadings for the various individual fuse links :
63-A fuse link : Imax = 63 A x 0.7 = 44A
50-A fuse link : Imax = 50 A x 0.7 = 35A
35-A fuse link : Imax = 35 A x 0.7 = 25A
25-A fuse link : Imax = 25 A x 0.9 = 22.5A
20-A fuse link : Imax = 20 A x 0.9 = 18A
16-A fuse link : Imax = 16 A x 1 = 16A
10-A fuse link : Imax = 10 A x 1 = 10A
6-A fuse link : Imax = 6 A x 1 = 6A
2 - The following additional reduction-factors must be used in installation sites with ambient
temperatures > 25°C
