IEC 63522-24:2025 pdf download,Electrical relays – Tests and measurements – Part 24: Load transfer.
IEC 63522-24:2025 outlines testing procedures, including the relevant severities and conditions, aimed at evaluating the performance of Devices Under Test (DUTs) under anticipated conditions of transportation, storage, and various operational scenarios. This document specifically defines a test designed to verify that a multipole relay can successfully transfer one source to another. By establishing these testing criteria, the standard ensures that multipole relays are assessed for their reliability and functionality in real-world applications, thereby enhancing their overall performance and safety.
