This provides improved safety related to isolation and protection of 2-Pole and 3- Pole electrical circuits by ensuring that the correctly related poles are removed at the 2 1 3 4 same time. (See Figure 2. Unique Conversion Capability Fig. 5.) Unique Conversion Capability The standard fuse holders can be readily converted from Dual front connection to front/back stud and double-back stud Figure 5. Two/Three connection types at the point of use. This is achieved with a Mounting Pole Ganging. unique back stud accessory and the use of a screwdriver. Capability See conversion sequence in Fig. 2. Steps 1, 2 and 3 show The design as standard provides both bolted panel and removal of ferrule end and insertion of back stud accessory DIN rail mounting features. The DIN rail mounting facility to give the front/back stud connection type. This sequence for each of the various dimensioned ratings is so designed repeated at the opposite end gives the double-back stud as to give equal height and depth above the DIN rail. connection type shown in step 4. Hinged Internal Shields Unique Cable Termination Non-removable full shrouding of live parts within the fuse The fuse holders unique cable terminations are designed base is provided by the use of hinged shields. The positive for user convenience and to ensure captive nature of these ensures that they cannot be long-term reliability. They incorporate omitted during installation and are so designed that stainless steel saddles and insertion of the fuse carrier can only be made with them hardened termination screws, correctly positioned. maintaining permanent cable clamping to profiled contact plates. Neon Indicator The main electrical contact path Neon clip-in indicator between the cable and fuse link tag accessories are is shown highlighted. This permits available providing clear the use of high tightening torques location and status without damage to cables or threads of fuses which and provides resistance to high have opened. (See Figure 3. Unique cable pull out forces. (See Fig. 3.) Fig. 6.) Cable Termination The fuse holders are supplied with the hardened termination screws backed out ready for cable insertion, saving installation time. Hinged Captive Screws The fuse fixing screws to fuse carrier are Figure 6. held in captive hinges providing ease Neon Indicators. of fixing and preventing loss during installation. Circuit (See Fig. 4.) Identification The fuse carrier has a marking label for ease of circuit identification. Figure 4.
