Key Topics and Requirements
- Scope and harmonization: Clause and numbering aligned with IEC/ISO directives and IEC 62271-1:2017 for consistent terminology and structure.
- Ratings (Clause 5): Rated voltages, insulation levels, continuous and short-time withstand currents, peak currents, bus-transfer current/voltage and new values for specific switching duties (moved from annexes to Clause 5).
- Mechanical and electrical classification: New mechanical endurance class for earthing switches (M1) and revised classifications for short-circuit making and electrical endurance.
- Switching capabilities: Added classifications and ratings for bus-transfer, bus-charging and induced-current switching capabilities; new ratings for ice-coating conditions.
- Design and construction: Revised requirements for position-indicating devices, isolating distances, interlocking devices, locking, earthing arrangements, mechanical strength and maximum operating force.
- Type tests and test procedures (Clause 7): Updated dielectric, mechanical and functional tests, revised validation criteria, mandatory high/low temperature tests when service limits exceed +40 °C or below −5 °C, and new Annexes:
- Annex B: Current-switching capability required
- Annex C: Tolerances on type-test quantities
- Annex E: Extension of validity of type tests
- Interlocking and position indication: New withstand and testing requirements for interlocks and more practical verification methods for position-indicating technologies.

Part 102: Alternating current disconnectors and earthing switches
FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of 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, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC
Publication(s)"). 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. 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 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 IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maxi
