LHR Fuse Holder
Used as in-line protection for
fluorescent fixtures, the Littelfuse
LGR and LMF series fuses and LHR
holder offer increased safety and
reliability to lighting systems. On a
277 volt system, a fault occurring
in an unfused fixture could take out
the entire branch circuit affecting
2.25"
as many as 100 fixtures. This could
cause safety problems as well as
shut down operations.
By individually fusing fixtures, these
problems will be avoided. The
0.50"
added benefits of this is the ability to quickly identify the problem fixture
and reduce the repair time.
Fuse holders are rated up to 10 amperes at 300 volts and are equipped
with 7" 18 AWG leads. Order part number LHR 000 for two leads, and
part number LHR 001 for one lead with the other terminal used for
insertion of 18 AWG ballast lead.
