Applies to all switchgear and their assemblies for alternating current of rated voltages of 72,5 kV and above for indoor and outdoor installation, including their supporting structure rigidly connected to the ground. Where switchgear and their assemblies are not ground mounted, e.g. in a building, conditions for application are subject to agreement between users and manufacturers. The seismic…

Deals with the safety of electrically operated commercial hoods intended for installation above commercial cooking appliances such as ranges, griddles, griddle grills and deep fat fryers, and not intended for household use. The hoods included in this standard are used, for example in restaurants, canteens, hospitals, and commercial enterprises such as bakeries, butcheries. The rated voltage being…

Gives rules for AC circuit-breakers, the main contacts of which are to be connected to AC overhead contact lines; the nominal voltage of these circuits is in accordance with IEC 60850. Complements the general requirements given in IEC 60077-2.

Donne les règles relatives aux disjoncteurs dont les contacts sont destinés à être connectés aux caténaires monophasées. La tension nominale de ces circuits est conforme à la CEI 60850. Est un complément aux prescriptions générales données dans la CEI 60077-2.

This National Standard of Canada is equivalent to International Standard CEI/IEC 61558-2-1:1997 (first edition 1997-02). 1 Scope Replacement: This part 2 of IEC 61558 applies to stationary or portable, single-phase or polyphase, aircooled separating transformers, associated or not, having a rated supply voltage not exceeding 1000 V a.c., a rated frequency not exceeding 500 Hz, and a…
