Foreword
The text of the International Standard IEC 60077-2:1999, prepared by IEC TC 9, Electric
railway equipment, together with the common modifications prepared by SC 9XB,
Electromechanical material on board of rolling stock, of Technical Committee CENELEC
TC 9X, Electrical and electronic applications for railways, was submitted to the Unique
Acceptance Procedure and was approved by CENELEC as EN 60077-2 on 2002-03-01.

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) 2003-03-01

- latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2005-03-01

This Part 2 shall be read in conjunction with EN 60077-1.

In this European Standard the common modifications to the International Standard are
indicated by a vertical line in the left margin of the text.

Subclauses, tables and figures which are additional to those in IEC 60077-2 are prefixed "Z".

Annexes designated "normative" are part of the body of the standard.
Annexes designated "informative" are given for information only.
In this standard, annexes A and ZA are normative and annex B is informative.
Annex ZA has been added by CENELEC.

Introduction
This product standard is Part 2 of the EN 60077 series of product standards:
Railway applications - Electric equipment for rolling stock
- Part 1: General service conditions and general rules,
- Part 2: Electrotechnical components - General rules,
- Part 3: Electrotechnical components - Rules for d.c. circuit-breakers,
- Part 4: Electrotechnical components - Rules for a.c. circuit-breakers,
