Household and similar electrical appliances - Safety - Part 2-34: Particular requirements for motor-compressors

IEC 60335-2-34:2021 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition.

IEC 60335-2-34:2021 deals with the safety of sealed (hermetic and semi-hermetic type) motor-compressors, their protection and control systems, if any, which are intended for use in equipment for household and similar purposes and which conform with the standards applicable to such equipment. It applies to motor-compressors tested separately, under the most severe conditions that may be expected to occur in normal use, their rated voltage being not more than 250 V for single-phase motor-compressors and 600 V for other motor-compressors.

This standard also covers:

- multi-speed motor-compressors, that are motor-compressors, the speed of which can be set to different values;

- variable capacity motor-compressors that are motor-compressors where the capacity of the compressor is controlled at fixed speeds.

Examples of equipment which contain motor-compressors are:

- tumble dryers (IEC 60335-2-11);

- re
