Foreword
The text of the International Standard IEC 60898-2:2000 + A1:2003, together with common modifications
prepared by the Technical Committee CENELEC TC 23E, Circuit breakers and similar devices for household
and similar applications, was submitted to the Unique Acceptance Procedure and was approved by
CENELEC as EN 60898-2 on 2005-06-01.
This European Standard supersedes EN 60898-2:2001.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2007-03-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2010-06-01

line in the left margin of the text.
This Part 2 is to be used in conjunction with EN 60898-1:2003 + corrigendum February 2004 + A1:2004.
When a particular subclause of Part 1 is not mentioned in this Part 2, that subclause applies as far as is
reasonable. Where this Part 2 states "addition", "modification" or "replacement", the relevant text of Part 1 is
to be adapted accordingly.
In this standard, the following print types are used:

1 Scope and object
This clause of Part 1 is applicable except as follows:
Addition at the end of the first paragraph:
This standard gives additional requirements for single- and two-pole circuit-breakers which, in addition to the
above characteristics, are suitable for operation with direct current, and have a rated d.c. voltage not
exceeding 220 V for single-pole and 440 V for two-pole circuit-breakers, a rated current not exceeding 125 A
and a rated d.c. short-circuit capacity not exceeding 10 000 A.
NOTE This standard applies to circuit-breakers able to make and break both a.c. current and d.c. current.
Delete the last two paragraphs.
2 Normative references
This clause of Part 1 applies.
3 Definitions
Clause 3 of Part 1 applies with the following modification:
Addition:
3.5.10.3
time constant
the rise time T = L/R (ms) of a prospective direct current to reach a value of 0,63 times the maximum peak
current
4 Classification
Clause 4 of Part 1 applies with the following modifications:
4.1 According to the number of poles
Replacement:
– single-pole circuit-breakers;
– two-pole circuit-breakers with two protected poles.
4.5 According to the instantaneous tripping current (see 3.5.17)
Delete D-Type.
Addition:
4.7 According to the time constant
– Circuit-breakers suitable for d.c. circuits with a time constant of T ≤ 4 ms.
– Circuit-breakers suitable for d.c. circuits with a time constant of T ≤ 15 ms.
NOTE It is assumed that short-circuit currents of 1 500 A are not exceeded in installations in which, due to the loads connected, time
constants in normal service up to 15 ms can occur. Where higher short-circuit currents may occur, the time constant of T = 4 ms is
considered sufficient.

Applicable for a.c. voltages:
NOTE 1 In IEC 60038 the network voltage value of (230/400) V has been standardized. This value should progressively
supersede the values of (220/380) V and (240/415) V.
NOTE 2 Wherever in this standard there is a reference to 230 V or 400 V, it may be read as 220 V or 240 V, and 380 V or
415 V respectively.
NOTE 3 Circuit-breakers complying with the requirements of this standard may be used in IT systems.
Two-pole circuit breakers rated 230 V may have one or two protected poles.
Two-pole circuit breakers rated 400 V shall have two protected poles.
Three-pole circuit breakers shall have three protected poles.
Four-pole circuit breakers may have three or four protected poles.
The manufacturer shall declare in his literature the minimum voltage for which the circuit-breaker is
designed.
