gG Protection 1 Pole Cylindrical Fuse Holder For 22x58mm 100A 690V Fuse

1 Pole Cylindrical Fuse Block RT19-100 AM4 For 22x58mm 100A 500V 690V gG Fuse Link

Applications Of The Cylindrical Fuse Block RT19-100 AM4

These fuse holders are supporters for fuses with size up to 22 x 58mm. They are capable of working under heat caused by rated current and expected short impacting current up to 100KA. It can also function as a fuse disconnecting switch by multiphase combination. There are two in/out lines at the RT18L type has a safety lock to lock the fuse carrier when disconnected to avoid wrong operation; It can also be equipped with an indicator, which goes on when the fuse link breaks.
Rated insulate voltage up to 690V; Working frequency 50Hz AC; Conventional free air thermal current up to 125A; Compliant with GB13539.1, GB13539.2, GB13539.6, GB14048.3 and IEC269-1, IEC269-2, IEC2690201, IEC947-3.

Design Features Of The Cylindrical Fuse Block RT19-100 AM4

After the plastic-injected case is equipped with contacts and fuse link, the bases are formed by welding or riveting both capable of being multi-phase structured, FB15C, FB16-3J, FB19C-3J, RT19 are open-structure, and others are semiconcealed structure. There are five fuse sizes available to choose from for the same fuse base of RT18N, RT18B and RT18C. There are two sets of in-out lines for RT18N. One is installed with fuse links of the according size. The other is a permanent open contacts with double breaking points. The whole base unit can cut the power. RT18 bases are all DIN rail installed, among which the RT18L is equipped with safety lock against wrong operation in the breaking state.

Construction Feature Of The Cylindrical Fuse Block RT19-100 AM4

This series of fuse consists of fuse link and fuse base. The variable cross-section fuse body made by pure copper piece (or copper wire, silver wire, silver piece) is sealed in the fusion tube which is made by the high strength porcelain or epoxy glass cloth pipe, there is full of the high-purity quartz sand processed after chemistry to take the extinguishing of arc medium in the tube. The two sides of the fuse use the spot welding to reliably connect with the end plate and to form the cylindrical cap shape structure. Fuse base suppressed by the resin or plastic casing fitted with contacts and contains the fusion pieces, the connection made by riveting as the support of the appropriate size fuse body parts. This series of fuse has many merits such as small in size, convenient for installation, safe in usage, beautiful in appearance and so on.
