MULTIBLOC® 2.RST8 - Mersen

MULTIBLOC ® 2.RST8size 2, 400A, 690VAC, design for bus bar installation, triple poleIEC LV NH Fuse switch disconnectorThe production programme of MULTIBLOC ® 2.RST9 comprises NH fuse switchdisconnectors for 400A.Products are designed in triple pole units for direct installation on to 40mm and60mm bus bar systems.For installation of MULTIBLOC ® NH fuse switch disconnectors of different sizes indistribution units with central cover, respective covers are used to obtain a uniformprofile in height and length.MULTIBLOC ® size 2 are designed for NH fuse-links in accordance with IEC/EN60269-2, VDE 0636-2, size 2: 400A.The system is a modular system, which allows the installation and combination ofindividual components. MULTIBLOC ® offers the user the possibility of fast and easyinstallation as well as a high degree of security during installation and maintenance.Features Benefits• z Touch protection IP 20 - when fuse link is in test mode IP rating is maintained• z Parking position of switch operating cover even with fuse links inserted• z Direct installation on to bus bar (snap on)• z Switch can still be adjusted after being snapped on to bus bars and fixed afteradjustment• z For 40 and 60 mm bus bar systems• z Universally useable for bus bars with thickness of 5 - 10 mm and widths of12–30 mm• z Symmetrical switch - suitable for bottom/top cable terminal connections• z Varieties of cable termination: screw, bolt, clamp strap, extendable for V-terminal- optional• z Electronic or electro-mechanic fuse monitoring - optional• z Cover for touch protection for direct installation on to bus bar systems - optionalStandardsIEC/EN 60 947-3For NH-fuse links size 2 inaccordance with IEC/EN 60 269-2,VDE 0636-2Applications• z Panel boards for industrial use• z Feeder pillars for industrial use• z Meter distribution units• z Measuring transformer cabinets• z Transmitting stations for telecommunicationsTechnical data overviewVolt (VAC) 690 VACVolt (VDC) 440 VDCAmper (A) 400 ASize per Standard 2Montageart bus bar installationUe = AC 400 V; Ie = 400 ASCCRUe = AC 500 V; Ie = 400 AUe = AC 690 V; Ie = 315 ASwitchability triple pole switching80kA80kA80kALow Voltage Switchgearwww.ep.mersen.com/ DS-LABCMB2-01-05111
