Fuse - Combination Units - BS EN 60947-3
Many people are attracted to fuse-combination units by their
simplicity in application and their reliability in operation. They are
particularly useful for use on very high prospective fault level
systems where the high energy limiting characteristic of the HRC fuse
can be effectively utilised. In the past fuse-combination units came in
two forms:
Switch Fuse A switch in which one or more poles
have a fuse in series.
Fuse Switch A switch in which one or more poles
have a fuse carrier/link which forms the
moving contact.
The de nitions of these two basic types of fuse combination units
have now been extended to include units suitable for making,
breaking and isolation and units which are only suitable for providing
isolation for maintenance work.

However, in order to keep the selection of fuse-combination units as
simple as possible, Hager offer a range of high performance double
break switch-fuses, which also satisfy the isolating requirement of the
British standard. These are correctly shown as
and de ned as a Fuse Combination Switch.
Switch disconnectors - BS EN 60947-3. A range of switch
disconnectors (isolators) are available for use on lower current
ratings from 20A to 125A, these switches are rated at AC-22 and
provide a cost effective alternative to the fuse combination switch
especially where the utilisation category AC-23 is not required. ie;
mixed resistive and inductive loads. These may be used at AC-23
providing they are derated in accordance with Table 9 page 3.53.
Utilisation categories
Utilisation categories are not new but they are important because
they help the designer or speci er identify the correct unit for a
particular application.
The designation of the utilisation category is made up of three parts:
1. The pre x AC or DC, which indicates the nature of the current.
2. The two digit number, which indicates the type of application
the unit is suitable for:
20 Connecting and disconnecting under no-load.
21 Switching of resistive loads.
22 Switching of mixed resistive and inductive loads.
23 Switching of highly inductive loads.
3. The suf x A or B, which indicates whether the unit is suitable
for frequent or infrequent operation.
A Frequent operation
B infrequent operation.
For example a fuse-combination unit feeding a 400V AC circuit of
mixed resistive and inductive loads which would need to be operated
frequently would require a minimum utilisation category of AC-22A.
If the load was highly inductive, i.e. motor loads, then the minimum
utilisation category would be AC-23A.
Generally, category AC-23 does not cover the switching of
capacitors. Usually this is the subject of agreement between
manufacturer and user.
Motor Power Circuit Protection
Fuse-combination units can be used very effectively for motor power
circuit protection, the energy limiting HRC fuse offering very good
protection to its associated starter. Category AC-23A should be
speci ed for this duty. Special motor circuit protection fuse links are
available which eliminate the need to t a larger bodied fuse just to
take care of the starting current of the motor.
The protection of motor power circuits should not be confused with
the direct switching of a single motor. If a fuse-combination unit is
required to perform this function then it must comply with the
requirements of Appendix A of BS EN 60947-3 which makes
provision for different utilisation categories for this application.
