Approvals & Standards
Key features & benefits
The production programme of MULTIBLOC® 1.RST8 comprises NH fuse switch disconnectors for 250A.
Products are designed in triple pole units for direct installation on to 40 mm and 60mm bus bar systems.
For installation of MULTIBLOC® NH fuse switch disconnectors of different sizes in distribution units with central cover, respective covers are used to obtain a uniform profile in height and length.
MULTIBLOC® size 1 are designed for NH fuse-links in accordance with IEC/EN 60269-2, VDE 0636-2, size 1: 250A.
The system is a modular system, which allows the installation and combination of individual components. MULTIBLOC® offers the user the possibility of fast and easy installation as well as a high degree of security during installation and maintenance.
