The input fuses must be of ultrarapid type (U.R.). I²t must be<br />
smaller or equal to 75% of the SCR value indicated above<br />
(A²s). These fuses protect the SCR against short-circuit. Instead<br />
of U.R. fuses you can also use normal fuses that protect<br />
the installation against short-circuit, but this type of fuse does<br />
not protect the SCR.<br />
