Preface<\/strong><\/p>\n

This is the second edition of CSA C22.2 No. 269.4, Surge protective devices – Type 4 – Component assemblies. It supersedes the previous edition published in 2014. This Standard is one in a series of standards dealing with surge protective devices. This Standard is issued by CSA Group under Part II of the Canadian Electrical Code. <\/p>\n

For general information on the Standards of the Canadian Electrical Code, Part II, see the Preface of CAN\/CSA-C22.2 No. 0. <\/p>\n

This edition incorporates numerous changes throughout to align the requirements with the revisions and updates made to other standards in this series. <\/p>\n

Scope<\/strong><\/p>\n

1.1
This Standard covers component assembly surge protective devices (SPDs) consisting of two or more Type 5 components, intended for use in Type 1, 2, or 3 SPD applications or installation in other electrical equipment. <\/p>\n

Note: SPD components containing integral thermal devices are within the scope of CSA C22.2 No. 269.5. <\/p>\n

1.2
Type 4 component assemblies are designed for repeated limiting of transient voltage surges as specified in this Standard on 50 or 60 Hz power circuits over 42 V and not exceeding 750 V. <\/p>\n

1.3
The surge protective component used in a Type 4 component assembly may include but not be limited to metal oxide varistors (MOVs), silicon avalanche diodes (SADs), spark gaps, and gas discharge tubes (GDT). <\/p>\n

1.4
This Standard does not apply to EMI filters which may have surge suppression characteristics as covered in CSA C22.2 No. 8. <\/p>\n

1.5
The values given in SI units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only. <\/p>\n

1.6
In this Standard, 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. <\/p>\n

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. <\/p>\n

Notes to tables and figures are considered part of the table or figure and may be written as requirements. <\/p>\n

Annexes are designated normative (mandatory) or informative (nonmandatory) to define their application.<\/p>\n","protected":false},"excerpt":{"rendered":"
