Part 3: Two-pole low-voltage type
FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, the IEC publishes International Standards. Their preparation is
entrusted to technical committees; any IEC National Committee interested in the subject dealt with may
participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. The IEC collaborates closely with the International Organization
for Standardization (ISO) in accordance with conditions determined by agreement between the two
organizations.
2) The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, an
international consensus of opinion on the relevant subjects since each technical committee has representation
from all interested National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical reports or guides and they are accepted by the National Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61243-3 has been prepared by IEC technical committee 78: Live
working.
The text of this standard is based on the following documents:
FDIS Report on voting
78/251/FDIS 78/257/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
Annexes A, B, C, D and E form an integral part of this standard.
Annex F is for information only.
The contents of the corrigenda of May 2000 and of December 2000 have been included in
this copy.

INTRODUCTION
Some low-voltage detectors have been in use for general detection of the state of electrical
circuits.
The detector covered in this standard is very specific in the sense that it is not a measuring
instrument. This detector complies with special requirements for live working thus providing a
high level of safety to protect qualified users performing tests on electrical networks and to
indicate clearly the voltage states "voltage present" and/or "voltage not present".

LIVE WORKING – VOLTAGE DETECTORS –
Part 3: Two-pole low-voltage type
1 Scope
This part of IEC 61243 is applicable to two-pole voltage detectors to be used on electrical
systems for nominal voltages not exceeding 1 000 V a.c. and/or 1 500 V d.c. and below 500 Hz
(nominal frequencies). The detector types are classified as follows: voltage class A: up to and
including 500 V a.c./750 V d.c.; voltage class B: up to and including 1 000 V a.c./1 500 V d.c.
This part of IEC 61243 also applies to supplementary functions such as phase indications,
rotating field indications, and continuity checks (see annex E). Furthermore, it applies to
accessories such as crocodile clips, detachable leads and contact electrode extensions.
Unless otherwise specified, all the voltages defined in this standard refer to phase-to-phase
voltages of three-phase systems. Detectors may be used in other than three-phase systems,
then the applicable phase-to-phase or phase-to-earth (ground) voltages are to be used to
determine the operating voltage.
Low-voltage detectors covered by this standard are not intended to provide measurement of
absolute values.
Measuring devices are excluded from this standard.
NOTE – The requirements for measuring devices are specified in IEC 61010-1 and IEC 61010-2-031.
