Scope
This part of IEC 60898 applies to a.c. air-break circuit-breakers for operation at 50 Hz or
60 Hz, having a rated voltage not exceeding 440 V (between phases), a rated current not
exceeding 125 A and a rated short-circuit capacity not exceeding 25 000 A.
As far as possible, it is in line with the requirements contained in IEC 60947-2.
These circuit-breakers are intended for the protection against overcurrents of wiring
installations of buildings and similar applications; they are designed for use by uninstructed
people and for not being maintained.
They are intended for use in an environment with pollution degree 2
They are suitable for isolation.
Circuit-breakers of this standard are suitable for use in IT systems provided that the
requirements of HD 384.4.473 are complied with.
This standard also applies to circuit-breakers having more than one rated current, provided
that the means for changing from one discrete rating to another is not accessible in normal
service and that the rating cannot be changed without the use of a tool.
This standard does not apply to
– circuit-breakers intended to protect motors;
– circuit-breakers, the current setting of which is adjustable by means accessible to the user.
For circuit-breakers having a degree of protection higher than IP20 according to
EN 60529, for use in locations where arduous environmental conditions prevail (e.g.
excessive humidity, heat or cold or deposition of dust) and in hazardous locations (e.g. where
explosions are liable to occur), special constructions may be required.
Requirements for circuit-breakers for a.c. and d.c. operation are given in EN 60898-2.
Requirements for circuit-breakers which incorporate residual current tripping devices are to
be found in EN 61009-1 and EN 61009-2-1.
Supplementary requirements may be necessary for circuit-breakers of the screw-in types.
A guide for co-ordination under short-circuit conditions between a circuit-breaker and another
short-circuit protective device (SCPDs) is given in annex D.NOTE 2 For an environment with a higher pollution degree, enclosures giving the appropriate degree of protection
should be used.
NOTE 3 Circuit-breakers within the scope of this standard may also be used for protection against electric shock
in case of fault, depending on their tripping characteristics and on the characteristics of the installation. The
criterion of application for such purposes is dealt with by installation rules.
NOTE 4 Recommendations for the dimensional coordination between enclosures and circuit breakers for
mounting on rail according to EN 60715 or equivalent means are given in the CENELEC report R023-001.
This standard contains all requirements necessary to ensure compliance with the operational
characteristics required for these devices by type tests.
