in accordance with IEC/EN 60 269, VDE 0636
Key features & benefits
The production programme of MULTIBLOC® 800VAC comprises NH fuse switch disconnectors for 800VAC voltage application. This range includes Size 00 (00.ST9), Size 1 (1.ST8), Size 2 (2.ST8) & Size 3 (3.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 00,1, 2 & 3 are designed for NH fuse-links in accordance with IEC/EN 60269, VDE 0636, size 00, size 1, size 2 and size 3, 80A, 160A, 250A and 315A.
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
