This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard.

Scope

1.1
This Standard applies to surge protective devices (SPDs) intended for:

a) 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 between the secondary of the service transformer and the line side of the service equipment overcurrent protective device. These devices may also be installed on the load side of the main overcurrent protective device;

d) installation where external overcurrent protection may not be present; and

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

1.2

C22.2 NO. 269.5-17 - Surge protective devices - Type 5 - Components

Preface

This is the second edition of CSA C22.2 No. 269.5, Surge protective devices Type 5 - Components. It supersedes the previous edition published in 2014.

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

The previous edition was written with the intent that the components tested to the requirements of this Standard were intended for use within a Type 1, Type 2, or Type 3 SPD device. This new edition was updated to allow for the testing and certification of components that might not necessarily be destined for use within an SPD device, but may instead be used within the circuitry of a domestic appliance or other such equipment.

This edition also includes a new test section for thermal protective devices, a provision to allow the manufacturer to specify nominal discharge current levels, and numerous other minor updates throughout.

Scope

1.1
This Standard applies to surge protective device (SPD) components designed to mitigate the effects of transient overvoltages and surge events and intended for use in surge protective devices (SPDs) or in non-SPD applications.

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
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.
