1 FUSE HOLDERS, FUSE BASES AND SUPPORTS IEC NH FUSE BASES FEATURES & BENEFITS Polyester insulating bases Silver-plated contacts High-pressure spring contacts Screw or rail mounting Multipolar bases available Connecting cable: 50mm APPLICATIONS For fuse-links with rated voltages up to 690VAC and 440VDC NH fuse-bases are available for delivery in single-pole and three-pole designs and can be closely mounted in parallel rows. Each three-pole base is upplied with two phase-partition walls. NH-ISO plugon covers which clip onto the contact springs can also be supplied for these bases. Plastic fuse-bases sizes 00 to 3 have a single-part plastic base while size 4 has a metal baseplate with 2 ceramic bases. The stable silver-plated contact springs are made of electrolytic copper and formed from one piece. Separate springing is provided by highly resilient captive steel springs, making the contact invulnerable to high thermal stress. Size 4 NH fuse-bases are designed for size 4 fuse-links with 8 mm contact blades. Indirect touch protection fuse bases: no microswitch possible.
