Preface

This is the first edition of CSA C22.2 No. 269.5, Surge protective devices Type 5 – Components. This Standard is one of a series of standards dealing with surge protective devices. Upon publication of the entire series, the requirements in these Standards will supersede CSA TIL I-11B on surge protection. This Standard is issued by CSA Group under Part II of the Canadian Electrical Code.

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

Scope

1.1
This Standard applies to surge protective device (SPD) components designed to mitigate the effects of transient overvoltages and surge events when used on electrical distribution systems rated at not more than 750 volts.

1.2
SPD Components containing integral thermal devices are within the scope of this Standard.

1.3
Components include but are not limited to metal oxide varistors (MOVs), silicon avalanche diodes (SADs), spark gaps (open or sealed type), and gas discharge tubes (GDT).

1.4
This Standard does not apply to products that are combinations of components nor to assemblies that use these components as covered in CSA C22.2 No. 269.4.

1.5
Components such as inductors or capacitors and other essentially linear components are not considered SPDs.

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.

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.
