scope:

This standard applies to any component intended to or for use in the protection of low voltage (1000V and less) ac power circuits from transient voltage surge.

Transient Voltage Surge Suppression equipment and/or circuits used in Transient Voltage Surge Suppression shall comply with all applicable requirements in IEEE C62.45 (IEEE Recommended Practice on Surge Testing for Equipment Connected to Low-Voltage (1000V and Less) AC Power Circuits) and in IEEE C62.62 (IEEE Standard Test Specifications for Surge-Protective Devices for Low Voltage AC Power Circuits).

Purpose

This standard states Approval requirements for Transient Voltage Surge Suppression Devices (Type 2 Surge Protective Device per NFPA 70 Article 285).

Approval criteria may include, but are not limited to, performance requirements, marking requirements, examination of manufacturing facility(ies), audit of quality assurance procedures, and a follow-up program.
