  60269-4 and BS88: Part 4. Ratings from 6-900A at 240V a.c. and
  6-710A at 660/690V a.c. For the protection of semiconductor
  devices requiring high speed disconnection from faults.

Our comprehensive range offers a selection of fuses to cater for
many applications:

Compact 415V a.c. S type industrial fuselinks complying with BS EN
60269-1 (BS88: part 1) or BS88: Part 2 with ratings from 2 to 1250A.
Skilful design techniques have meant that power dissipation has frequently
been reduced despite the significant reduction in barrel size. Many ratings
have also been tested for use in circuits up to 250V d.c.

Compact 415V a.c. S type motor circuit protection fuselinks complying with
BS EN 60269-1 (BS88: part 1) or BS88: Part 2 with ratings from
20M25A to 400M500A. This extended range of fuselinks is designed to
withstand the inrush current associated with direct on line start motors
whilst saving cost on the size of equipment to which they are fitted by virtue
of their small dimensions.

Compact 240V and 415V a.c. SS, SN and SP type offset blade contact
fuselinks complying with BS EN 60269-1 (BS88: part 1) or BS88: Part 6
with ratings from 2 to 63A for use in industrial and commercial installations.

550V a.c. S type industrial fuselinks complying with BS EN 60269-1 (BS88:
part 1) or BS88: Part 2 with ratings from 2 to 800A are also available in the
most commonly used fixing centres. Also rated at 250V d.c.

Compact 415V a.c. J type feeder pillar fuselinks complying with BS88: Part
5 for use by the Electricity Supply Industry in distribution systems. Ratings
from 63-400A with 82mm fixing centres and 63-800A with 92mm fixing
centres for wedge tightening contacts and 63-250A in ferrule form for
single phase pole mounted cut outs.

NH type blade contact 500V a.c. fuselinks complying with IEC 60269-2-1
section 1 and with dimensions also to DIN43620/1. Ratings from 6-630A
in size C00 to size 4. For use in industrial applications where European
practice prevails.

Eaton MEM HRC fuselinks are manufactured to exacting standards using
precision assembly methods and undergo rigorous quality checking before
dispatch including resistance testing all production. This ensures that
performance will be consistent and conform with published characteristics
within close tolerances. Type tests on Eaton MEM equipment have been
performed using Eaton MEM fuselinks and the exclusive use of Eaton
MEM fuselinks in Eaton MEM equipment will extend the warranty period
to 3 years.

Eaton MEM industrial and general purpose fuselinks have a breaking range
and utilization category gG which replaces the old class Q1 fusing factor. "g"
indicates a full range breaking capacity fuselink and "G" indicates a fuselink
for general application.

Eaton MEM motor circuit protection fuselinks have a breaking range and
utilization category gM indicating a full range breaking capacity fuselink
for the protection of motor circuits. These fuselinks have a dual current
rating separated by the letter "M".

The lower current rating is the maximum continuous rating which also
determines the rating and size of equipment to which the fuse is fitted. The
higher current rating is the time current characteristic of the fuselink which
determines its ability to withstand the motor starting current. Their
selection frequently permits the use of lower rated switch and/or fusegear
than would be the case using gG fuselinks with a consequent cost saving.
Type gG fuselinks however may still be used and are the preferred option for
assisted start motors where starting currents are reduced.

Technical information for these products is available from Eaton MEM’s
Customer Services Department.

Eaton MEM fuselinks are designed and manufactured in accordance with a
Quality Management System in accordance with ISO 9001 assessed by BSI.
Most fuselinks are ASTA Certified for a breaking capacity of 80kA at 415V or
550V a.c. and are endorsed ASTA 20 CERT showing compliance with the rules of the ASTA 20 scheme which includes assessment of the Quality Management System to ISO 9002 and detailed auditing of fuselink manufacture.

Eaton MEM have for many years participated in developing and influencing
fuse standards through EIEMA and BSI at national level and IEC at
international level and therefore are able to produce designs incorporating
forthcoming changes to standards.

Eaton MEM HRC fuselinks, other than motor rated patterns, have utilization categories gG.

Schedules of equivalent fuselinks made by certain other manufacturers are included to assist in the selection of fuselinks having similar ratings, dimensions and fixing centres. No claim is made of identical performance under all conditions. Characteristic curves are available on request.

Motor Rated Fuselinks
BS 88 now aligns with the international fuse specification IEC 269. The concept of "fusing factor" has been replaced with "utilization category". Class Q1 fusing factor is now referred to as "gG" and motor rated fuselinks are referred to as "gM". Special motor rated fuselinks are listed. These are available in various barrel sizes, in each case fitted with special fuse elements. Their selection frequently permits the use of lower rated switch and/or fusegear than would be the case using Class gG fuselinks. This range of fuselinks has been ASTA certified for breaking capacity of 80kA at 415V AC.

Eaton MEM S-Type industrial bolted pattern fuselinks conform with BS 88: Part 2: 1988, have been ASTA certified for a breaking capacity of 80kA at 550V AC or 415V AC and have utilization categories gG.

These fuselinks are suitable for the back-up protection in motor circuits, having excellent time delay characteristics with low fusing factor and high rupturing capacity.

Fuses for use in motor circuits should be selected in accordance with the requirements for the protection of motor control gear as specified by the control gear manufacturer.
