fuse to ensure that the current flow is interrupted if an error occurs. U
U can be protected with a fuse cut-out each acc. to EN 60127-2 or with an
LS
electronic fuse each. Fuse cut-outs have to comply with the following techni‐
cal specifications acc. to EN 60127-2:
● G-fuse link
● Rated current 4 A
● Slow-blow
● Current pulse insensitive
● Large or increased switch-off capacity
● Rated voltage ≥ 60V DC
● Time-current characteristics: 275 % of the nominal current, correspond‐
ing to 11 A, maximum 80 s
