16.10 Fuses
ecosine
™ filters need external over-current protection for compliance with UL/cUL standard.
Fuses and associated fuseholders must be UL listed and rated for 100kA SCCR supplies. The
subsequent list shows requested fuse current ratings for UL class J and, where UL compliance is
not mandatory, for IEC class gG. The fuse rating is independent of the supply voltage.

A system with multiple ecosine
®
filters
paralleled for a high power load need each a
separate 3-phase line side fuse block,
corresponding to the respective filter and
according to above table.
The drive’s application manual may
prescribe line-side fuse protection as
well, which in this case either
corresponds to the sum of the filter fuse
ratings or, if lower, would request
separate drive fuses at its input.
An application, having one ecosine
®
filtering harmonics of several drives,
requires in any case line side fuse
protection of the drives as well as the
correct filter protection according to
above table.
16.11 Safety cover for filters with bus-bar terminals.
Once all filter terminals are properly
wired, replace the safety cover by
tightening the previously untightened
bolt.
