photovoltaic applications
Do not open
under load
414 681
1. GENERAL FEATURES
1-1 Brief description
- Single pole (1P) and 2-pole (2P) photovoltaic (PV) fuse carrier
for isolating and protecting DC circuits from PV panels for
applications up to 1000 V.
- For 10 x 38 mm cylindrical fuses
- Supplied with dividers (4146 82) and safety labels:
"Do not operate under load"
1-2 Use
- Use recommended according to recommendations in guide
UTE C 15-712-1
- Use with fuses specifically designed for the DC side of
PV applications
Recommended use:
- 1P fuse carrier: For installations with polarised PV panels
(with earthing of one of the polarities), protection of the poles
not connected to earth for each PV string
- 2P fuse carrier: For protection of both poles of each string
of non-polarised PV panels
