Title (German)
Elektrische Relais - Mess- und Prüfverfahren - Teil 38: Mechanische Verriegelung (IEC 63522-38:2025); Deutsche Fassung EN IEC 63522-38:2025
Overview
This part of IEC 63522 is used for testing all kinds of electrical relays and for evaluating their ability to perform under expected conditions of transportation, storage and all aspects of operational use. This document defines a standard test method for mechanical interlock. This test is applicable to the elementary relays which have the mechanical interlocking mechanism. Application of this document increases investment security for manufacturers and users, while testing laboratories and manufacturers are provided with defined information for testing.
