Application Data
The standard range of fuses for low voltage industrial and
general purpose applications meet the requirements of
BS 88 and IEC 60269. By using advanced fuse technology,
current ratings up to 400A have compact dimensions, but
retain standard dimensional and performance requirements.
These designs are for 315/240V systems. The standard
range of fuses are available from 2-1250A in the following
tag forms: Offset Blade - Offset Bolted - Center Bolted.
Supplementary ranges cover applications up to 660Vac and
500Vdc including those with nonstandard tag fixings.
Cooper Bussmann fuses are manufactured under quality
systems independently assessed to BS 5750 (ISO 9002) and
appropriate ratings carry the ASTA 20 endorsement.
Selecting fuses is relatively simple and effective. The
following notes cover the majority of applications. For further
information contact our Application Engineers at
636-527-1270.
Circuit Loading
The current rating of the fuse should not be less than the full
load current of the circuit. The circuit should be so designed
that small overloads of long duration will not be of frequent
occurrence.
Cable Ratings & Protection
There is an increasing move away from 70°C PVC insulation
to materials that are more environmentally friendly, for
example 90°C XLPE. The ratings of fusegear, switches,
accessories, etc. are generally based upon the equipment
being connected to conductors intended to be operated at a
temperature not exceeding 70°C in normal service.
In view of the above, it is recommended that the practice of
designs based upon conductor temperatures of 70°C be
regarded as the norm. The equipment manufacturer should
be consulted to ascertain the reduction of nominal current
rating of the equipment if conductor temperatures exceeding
70°C are used. In addition, an overriding factor is often
voltage drop.
Fuses with gG characteristics protect associated cables
against both overload and short-circuit current, provided that
the current rating of the fuse 1N is equal or less than the
current carrying capacity of the cable 1z.
In motor circuits, the motor starter will provide the overload
protection and the fuses will provide the short-circuit
protection. The maximum fuse size that can be used
depends upon the type of cable used and is determined
using the appropriate K factor. The following table gives the
maximum sizes of fuses that are recommended for two
popular cables with copper conductors, 70°C PVC (K = 115)
and 90°C thermosetting (K = 143).
