Dimensional Data

• Unique Conversion Capability.

• 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. 1. Steps 1, 2 and 3

show removal of end ferrule 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.

• 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 clamp-

ing to profiled contact plates.

• The main electrical contact path between the cable and

Fuse tag.

• This permits the use of high tightening torques without

damage to cables or threads and provides resistance to

high cable pull out forces. (See Fig. 2.)

• The Fuse Holders are supplied with the Hardened

Termination Screws backed out ready for cable insertion,

saving installation time.

• Hinged Captive Screws.

• The Fuse Mounting Screws to Fuse Carrier are held in

captive hinges providing ease of mounting and preventing

loss during installation. (See Fig. 3.)

• Two/Three Pole Ganging.

• 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 3 Pole electrical circuits by

ensuring that the correctly related poles are removed at

the same time. (See Fig. 4.)

• Dual Mounting Capability.

• 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.

• 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 operated

due to fault conditions. (See Fig. 5.)

• Circuit Identification.

• The Fuse Carrier has a marking label for ease of circuit

identification.

• Strip Length Marking.

• The length of cable insulation that should be stripped off is

shown on the side of the Fuse Base.
