Key features & benefits
The production programme of MULTIBLOC® 800VAC comprises NH
fuse switch disconnectors for 800VAC voltage application. This
range includes Size 1 (1.ST8) and Size 2 (2.ST8) Multibloc and answers
the specific needs of Photovoltaic application for using String
inverters rated at 800Vac.
They are designed for bottom fitting/panel installation and are
available in triple pole units.
For installation of MULTIBLOC® NH fuse switch disconnectors in
distribution units with central cover, respective covers are used to
obtain a uniform profile in height and length.
MULTIBLOC® size 1 and size 2 are designed for NH fuse-links in
accordance with IEC/EN 60269, VDE 0636, size 1 and size 2, 160A
and 250A.
MULTIBLOC® offers the user the possibility of fast and easy
installation as well as a high degree of security during installation and
maintenance.
Applications
- Power distibution and Motor protection
- Photovoltaic application: Protection on lines of String inverters rated at 800VAC
