CSA - C22.2 NO. 269.2-13

Surge protective devices - Type 2 - Permanently connected

inactive
Organization: CSA
Publication Date: 1 June 2013
Status: inactive
Page Count: 53
scope:

This Standard applies to surge protective devices (SPDs) intended for

) permanently connected applications designed for limiting surge voltages and discharging surge currents;

b) use on 50/60 Hz circuits over 42 V and up to 750 V ac;

c) installation on the load side of the main overcurrent protective device; and

d) indoor or outdoor use in accordance with the Canadian Electrical Code, Part I.

Equipment designed solely for other power disturbances such as notches, sags, and noise is not within the scope of this document.

SPDs discussed in this Standard contain at least one voltage limiting or voltage switching component for diverting surge currents or dissipating surge energy, or both. Examples of such components are metal oxide varistors, silicon avalanche diodes, spark gaps and gas discharge tubes. Ferroresonators, motorgenerators, uninterruptible power supplies, and filters containing only inductive or capacitive components are not considered SPDs in this standard.

General requirements applicable to this Standard are given in the latest edition of CAN/CSA-C22.2 No. 0

In CSA standards, "shall" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; "should" is used to express a recommendation or that which is advised but not required; and "may" is used to express an option or that which is permissible within the limits of the standard.

Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.

Notes to tables and figures are considered part of the table or figure and may be written as requirements.

Annexes are designated normative (mandatory) or informative (nonmandatory) to define their application.
