Application
Support parts of this series fuse for AC 50Hz, rated insulation voltage up to 690V, thermal current to 125A, mainly used in electrical wiring in size to 22 x 58 as the various use categories (gG, aM, aR, etc.) fuse support pieces. Support parts of this series with a fuse withstand thermal current and expected impact of current sprint to 100KA dynamic thermal stability capabilities. Combined with a multi-phase fuse isolators function. One model RT18N the fuse on the support of about two pieces of a road into the outlet, both isolated power function; RT18L with a safety locking device, lock the load in the off state can melt pieces, to ensure that no misuse; also with fuse indicator, lights indicating fuse is blown.
This series of fuse support pieces in line with national standards GB13539.1, GB13539.2, GB13539.6, GB14048.3 Work standards and international power IEC60269-1, IEC60269-2, IEC269-1, IEC947-3.
Structural features
This series of fuse supports the suppression of shell pieces of plastic contact and mounted on a set piece after melting by riveting or welding, have a heterogeneous structure can be formed. FB15C, FB16-3J, FB19C-3J, RT19 forthe open type, other models are semi-enclosed structure. Which RT 18N, RT 18B and RT 18C in the same dimensions of the base, choose from five different sizes of the configuration fuses; RT 18N has two inlet and outlet, all the way to configure the appropriate size of the fuse body, the other way for a double break point, often open contact, a single support piece with isolated power function; RT18-based support pieces are TH35mm rail mount, which RT 18L also with safety locking device to ensure that support disconnected pieces of misuse does not occur.
