IEC EN 60265-1 High Voltage Switches - Part 1: Switches for Rated Voltages Above 1 kV and Below 52 kV

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 60265-1 test. This part of IEC EN 60265 is applicable to three-phase alternating current switches and switch-disconnectors with tripping and breaking current ratings, for indoor and outdoor installations, for rated voltages above 1 kV and below 52 kV and for rated frequencies. This standard also applies to the actuation devices of these switches and their auxiliary equipment.

The general principles and provisions of this standard are also applicable to single-pole switches intended for application in single-phase systems. Requirements for dielectric tests and build and break tests must be in accordance with the requirements of the particular application.

The main purpose of this standard is to specify requirements for general purpose switches used in distribution systems.

General purpose switches will be suitable for the following service applications:

• Carrying continuous normal current;
• Mainly switching of active loads;
• Switching of distribution line closed-circuit circuits;
• Switching of no-load transformers;
• Switching the charging current of unloaded cables and overhead lines;
• Carrying short-circuit currents for a certain period of time;
• Making short circuit currents.

General purpose switches intended for use in isolated neutral systems or high impedance earthed systems must be capable of switching under earth fault conditions. Another purpose of this standard is to specify requirements for limited purpose and special purpose switches used in distribution systems.

Limited purpose switches shall have a rated normal current, a rated short-time withstand current, and one or more, if not all, of the switching capacities of the general purpose switch.
