How to choose the protection system

Maximum rated current
value of the fuse

The maximum rated current values of the fuse that can
be installed in the fuseholder are given in the table below.
These values depend on the rated voltage of the network
and conform to the maximum limits of the power dissipated
by the protection system, formed by the fuse and fuseholder.
ABB fuses and fuseholders allow all the requirements
established by the standards to be met in full safety.
The performance provided by ABB products allows a fuse with
a rated current that exceeds the limit dictated by standard
IEC 60269-2-1 to be installed in certain situations.

Use this table to find the cable length,
in meters, that is protected by a fuse.

Just cross the rated current of the fuse (in the columns)
with the section of the conductor (on the lines).
The resulting number corresponds to the protected length
of the conductor: for example, a 32 A fuse can protect up

2

to 214 meters of 6 mm

section cable. When there are two
values, it means that the maximum length of the cable is
between the two numbers given in the table.

E 9F aM cylindrical fuses

Delayed protection for motor starts

E 9F aM series fuses are the best way to protect against overloads and short-circuits together
with series fuse E90. They feature a delayed tripping curve and are therefore ideal for protecting
industrial motors that require high inrush current during the starting phase.
The E9FaM series is available for all the main sizes (8.5x31.5mm, 10.3x38mm,
14x51mm e 22x58mm) and with a wide range of rated current values (from 1A to 125A
and up to 690VAC). All the E9F series fuses conform to the RoHS directive and are
type-approved in accordance with the most important international naval marks.

Questions & answers

Technical and regulatory details
concerning the E 90 range

IEC 60947-3: switches, disconnectors,
switch-disconnectors and fuse-combination units

This standard establishes the requirements of a device to
ensure its suitability for disconnection and operation.

Disconnector:

A disconnector is a mechanical control device which, when
open, meets the prescriptions for the disconnection function
laid down by the international IEC 60947-3 standard.
Opening a disconnector ensures that downstream the circuit
is electrically isolated from upstream. This condition is
necessary if you need to operate on a network component,
e.g. during maintenance. Pursuant to the IEC 60364
standard, any maintenance operations on the installation are
prohibited unless circuits have been previously disconnected.

Fuse-disconnector:

This defines a fuseholder that also performs disconnecting
functions. Not all fuseholders are also disconnectors: to meet
this definition they must meet the requirements and pass the
tests provided for in the IEC 60947-3 standard.

Fuse-switch-disconnector:

According to the IEC 60947-3 standard, this definition
concerns a fuse-disconnector that enables switching under
load. Not all fuse-disconnectors enable this operation: to be
considered as a fuse-switch-disconnector a device must have
utilization category equal to AC-21B or above.

Utilization categories:

Not all devices intended for disconnection have the same
performance. The type of operation allowed depends on a
designation that specifically defines the methods of use,
i.e. the utilization category.

This identifies:
a. The nature of current (AC/DC)
b. The type of switching allowed (no load, resistive loads,

highly inductive loads, etc.)
c. The operation frequency
E 90 fuse-switch-disconnectors have AC-22B utilization
category up to 400V and utilization category AC-20B up to
690 V. The E 90 PV fuse-disconnectors have DC-20B
utilization category. E 90 50/125 fuse-disconnectors have
utilization category AC-20B.

Which loads can be disconnected using a product with
AC-22B utilization category?

The AC-22B utilization category allows occasional operation
of mixed, resistive and inductive loads with moderate
overloads in alternating current circuits. Mixed loads include:
transformers, corrected motors, capacitor batteries, discharge
lamps, heating, etc.

48 | E 90 range of fuse disconnectors and fuseholders

Which loads can be disconnected using a product with
AC-20B utilization category?

The AC-20B utilization category does not allow operation
under load. Disconnection is possible only by first
disconnecting the load through an appropriate switch.

IEC 60269-1: Fuses with voltage not exceeding 1000V
in alternating current and 1500V in direct current

This standard establishes the requirements of low voltage
fuses, and as a result the requirements of fuseholders as
devices intended to accommodate fuses.
This standard includes two different sections, with different
requirements depending on the type of individual using the
equipment:

IEC 60269-2: supplementary requirements for fuses for use

by skilled persons (mainly for industrial
application).

IEC 60269-3: supplementary requirements for fuses for use

by unskilled persons (mainly for household and
similar applicationss).

What is the difference between a IEC 60947-3-compliant
fuseholder and a IEC 60947-2-compliant fuseholder?

These are two complementary standards: IEC 60269-2
establishes the characteristics of fuses, and, from these
general requirements for fuseholders are derived. It is the
reference standard for overcurrent protection but not for
disconnection and switching.

Are fuseholders marked UR and UL equivalent to each
other?

They are different products and they comply with equally
different requirements. E 90/32 switch disconnectors conform
to IEC standards and accommodate midget fuses. However,
since they are recognized by the UL laboratories, by means of
the UR mark, they can be used as components in UL-certified
machines designed for the American market.
On the other hand, E 90/30 CC fuseholders are specifically
designed and tested in accordance with the American
standards. They are able to accommodate Class CC
cylindrical fuses, which possess particular limitation
characteristics. This means that it is forbidden to use

10.3 x 38 fuses that conform to IEC standards in E 90/30 CC
fuseholders.

The E 90 series were designed and certified in
accordance with the IEC 60269-2 standard which sets forth
the maximum rated current values envisaged for fuses and
fuseholders as summarized in the tables above.
Therefore, the characteristics according to which the units
were certified are shown on their rating plates.

Can fuses with rated current values higher than the
one indicated in the table be used?
For example, can a 22 x 58 mm 125 A fuse be used in a
E 90/125 fuseholder?

Yes, in compliance with the instructions provided by the
manufacturer, a fuse with a higher rated current than the one
indicated in the tables above can be used: it is necessary
to verify that the power dissipation value of the fuse does
not exceed the maximum acceptable power value of the
fuseholder. In this specific case, if a 22 x 58 mm fuse used at
125 A dissipates a maximum power which is equal to or less
than 9.5 W, it can be used in an E 90 125 fuseholder at a
rated current of 125 A.
Since the above statement is generally valid for aM-type
fuses, it has not to be forgotten the need to associate to it
an overload protection devices. In fact, the aM-type fuses,
unlike the gG-type ones, are designed to provide protection
only against short-circuits and would act on overloads only
after a long time, thus pushing the product beyond its own
physical limits, beyond which it would no longer be possible
to guarantee its proper operation.

Can instead, a 10.3 x 38 mm 32 A gG fuse be used in a

10.3 x 38 mm E 90/32 fuseholder with a rated voltage
exceeding 400 V?

In this specific case, an E 9F10 GG32 fuse dissipates 2.8 W
at 400 V rated voltage. Since an E 90/32 series fuseholder for

10.3 x 38 mm fuses achieves 3 W thermal dissipation, the
fuse in question can be used at 400 V rated voltage or less.
On the other hand, use of rated voltage exceeding 400 V fails
to allow the equipment to comply with the maximum
dissipated power limit.
