NH fuse bases are available in single and three-pole BF892 and can be mounted closely in parallel rows. Each three-pole base is provided with two phase separators. Contact protection covers that are attached to the contact springs can also be supplied. Plastic fuse bases of sizes 00 to 3 have a one-piece plastic base, size 4 has a metal base plate with 2 ceramic bases. The stable silver-plated contact springs are made of electrolytic copper and are formed from one piece. Highly resilient captive steel springs make the contact insensitive to high thermal loads. NH fuse bases of size 4 are designed for fuse links with 8 mm contact blades. A microswitch (250 VAC / 10 A, connection size 6.3 x 0.8 mm) can be used together with NH fuse links with firing pin. It indicates when the fuse melts or when no fuse link is inserted. Fuse base with indirect contact protection: No microswitch possible. Nominal impulse strength Uimp: 6 kV / 8 kV (sizes 00 / 0-4. IEC 60269 compliant, dimensions according to DIN 43620, DIN0636-2, 0636-2.
