Unique Cam Action Panel Drilling Plans, Viewed from Front of Panel • The fuse carriers are fitted with a cam for ease of removal from the fuse bases allowing significantly improved contact pressure between fuse carrier and fuse base contacts, with a corresponding enhanced electrical performance level. CL CL • This design overcomes a major problem of all existing dead front style fuse holders manufactured worldwide, which have to compromise between difficulties of fuse carrier removal from base and contact pressure achieved. 1.14" 29.0mm Lockable Safety Carriers 1.14" 29.0mm 0.13" 3.2mm Ref CM20CF 1.5N•m 1.11 lb-ft #2 CM30CF 1.5N•m 1.11 lb-ft #2 CM60CF 2.0N•m 1.48 lb-ft 2/0 CM100CF 2.0N•m 1.48 lb-ft 2/0 0.22" 1.46" ø5.5mm 37.0mm CM30CF 0.25" 6.35mm 0.13" 3.2mm CL 1.62" 41.0mm 0.13" 3.2mm 0.75" ø19mm 0.25" 6.35mm CM60B + 100CF 08-09 BU-SB09579 Page 1 of 3 0.75" ø19mm 0.25" 6.35mm CM20CF CL Max Cable Size 1.46" 37.0mm 0.59" ø15.0mm Mounting Torque and Cable Size 0.13" 3.2mm CL CL • This distinct feature ensures isolation can be achieved allowing maintenance to be carried out in safety.

Unique Conversion Capability The unique design of the carriers allows ganging to be readily achieved by the use of standard accessories. This provides improved safety related to isolation and protection of 2-Pole and 3Pole electrical circuits by ensuring that the correctly related poles are removed at the same time. (See Fig. 5.) Unique Conversion Capability The standard fuse holders can be readily converted from front connection to front/back stud and double-back stud connection types at the point of use. This is achieved with a unique back stud accessory and the use of a screwdriver. See conversion sequence in Fig. 2. Steps 1, 2 and 3 show removal of ferrule end and insertion of back stud accessory to give the front/back stud connection type. This sequence repeated at the opposite end gives the double-back stud connection type shown in step 4. Dual Mounting Capability Figure 5. Two/Three Pole Ganging. The design as standard provides both bolted panel and DIN rail mounting features. The DIN rail mounting facility for each of the various dimensioned ratings is so designed as to give equal height and depth above the DIN rail. Hinged Internal Shields Unique Cable Termination The fuse holder’s unique cable terminations are designed for user convenience and to ensure long-term reliability. They incorporate stainless steel saddles and hardened termination screws, maintaining permanent cable clamping to profiled contact plates. The main electrical contact path between the cable and fuse link tag is shown highlighted. This permits the use of high tightening torques without damage to cables or threads and provides resistance to high Figure 3. Unique cable pull out forces. (See Fig. 3.) Cable Termination The fuse holders are supplied with the hardened termination screws backed out ready for cable insertion, saving installation time. Non-removable full shrouding of live parts within the fuse base is provided by the use of hinged shields. The positive captive nature of these ensures that they cannot be omitted during installation and are so designed that insertion of the fuse carrier can only be made with them correctly positioned. Neon Indicator Neon clip-in indicator accessories are available providing clear location and status of fuses which have opened. (See Fig. 6.) Hinged Captive Screws The fuse fixing screws to fuse carrier are held in captive hinges providing ease of fixing and preventing loss during installation. (See Fig. 4.) Figure 6. Neon Indicators. Circuit Identification The fuse carrier has a marking label for ease of circuit identification. Figure 4. Hinged Captive Screws 08-09 BU-SB09579 Strip Length Marking The length of cable insulation that should be stripped off is shown on the side of the fuse base. Page 2 of 3 Data Sheet 4132 Figure 4.
