IEEE C62.72-2007

IEEE C62.72-2007 is a technical guide for the application of surge protective devices on low voltage AC power circuits rated 1000 volts or less. Focused on power, energy, and industry applications, it helps clarify how these devices are selected and applied to reduce transient overvoltage risk. For engineers, specifiers, and maintenance teams, the standard supports more consistent protection planning and better alignment between equipment needs and site conditions.

Overview of IEEE C62.72-2007

This document addresses the practical use of surge protective devices in low voltage AC power systems, where voltage surges can affect connected loads and electrical infrastructure. IEEE C62.72-2007 is intended to guide application decisions rather than define a single product design, making it useful when evaluating where protection is needed and how it should be coordinated with the electrical system. It is especially relevant in settings where transient protection, system reliability, and installation practices must be considered together.

Typical use cases

The guide is commonly used when planning surge protection for service entrances, distribution panels, motor control equipment, and other low voltage AC circuits in industrial or energy-related facilities. It may also support decisions for equipment rooms, process controls, and power distribution points where transient events could disrupt operations. IEEE C62.72-2007 is helpful when comparing protection approaches for different circuit locations and when documenting the basis for specifying surge protective devices in procurement or retrofit projects.

Why it matters

Using IEEE C62.72-2007 can help improve consistency in surge protective device application, which matters when electrical systems must perform reliably under transient conditions. It provides a structured reference for design control, installation planning, and technical review, helping reduce the chance of mismatched protection or overlooked exposure points. In practice, that can support safer operation, better equipment protection, and more defensible compliance decisions during specification, testing, or maintenance planning.
