3 1NBO 3/10 3/6 *instead of last outgoing fuse-switch-disconnector (100 mm wide) two fuse-switchdisconnectors up to 160 A (each 50 mm wide) can be placed. EXAMPLE: 1NBO-10-SS-1250 LV switchgear assembly consisting of 10 outgoings (up to 630 A), switch disconnector on incoming side and strip type fuse-switch-disconnectors on outgoing side, for rated current of 1250 A. Type tested IEC EN National standard N Design Free standing air insulated LV panel, intended for indoor installation, equipped with primary and secondary electrical equipment, with doors on the upper front side. Lighting installed at the top of the panel. Secondary equipment Incomer I: 1NBO-1250 i 1NBO-1600 Enclosure is made of 2 mm thick aluzinc sheet, doors are made of steel sheet protected against corrosion by electrostatic powder coating of RAL Fixation to the floor provided by fixation elements onto cable trench of 250 mm standard width. Outgoings II: 1NBO 3200 Entire enclosure and doors are made of 2,5 and 2 mm steel sheet, protected against corrosion by electrostatic powder coating of RAL Fixation to the floor provided by fixation elements onto cable trench of 250 mm standard width. Incomer Circuit-breaker, disconnector switch, fuse switch-disconnector or Cu-link. Standard incomer at right side of assembly. Standard horizontal connection, alternatively vertical. Measuring current transformers. Cable trench Secondary equipment Digital multimeter (I, U, P, cosö, f ), auxiliary relays with flag for switch indication, for transmission of signal of contact thermometer and Buchholz relay protection, together with selector switch for selection of thermal selection level, socket outlet, lighting, fuses and terminals. Outgoings Vertical fuse-switch-disconnector up to 630 A with V-terminals for cable connection up to 240 mm 2 or with bolt type cable connection on request.
