BS EN IEC 63522-37:2025

Electrical relays. Tests and measurements. Terminal temperature rise at rated load | Status: Current

1 Scope This part of lEC 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.

NOTE Examples for electrical relays in the sense of this document include electromechanical relays, reed relays, reed contacts, reed switches, solid state relays, time relays and technology combinations of these.

The object of this document is to define a standard test method to measure terminal temperature rise at rated load, included solder terminals, flat quick-connect terminations, screw and screwless type terminals, alternative termination types and sockets.
