About This Item
C37.20.3-2013 is a technical standard for enclosed interrupter switchgear in the 1 kV to 38 kV range, presented here as a redline edition for easier review of changes. It is relevant to power, energy, and industrial applications where medium-voltage switching equipment must be specified with care. By addressing design and performance expectations for this equipment class, C37.20.3-2013 helps support clearer procurement, safer application, and more consistent engineering decisions.
What is C37.20.3-2013?
C37.20.3-2013 defines requirements and guidance for enclosed interrupter switchgear used in medium-voltage systems. The document is intended to help users understand the construction, ratings, and functional expectations associated with this type of equipment. In practice, it serves as a reference for evaluating how enclosed interrupter switchgear should be designed, applied, and tested within electrical installations. As a redline standard, it is also useful for identifying revisions and tracking technical changes.
Where is C37.20.3-2013 used?
This standard is commonly used in facilities and projects that rely on enclosed interrupter switchgear for controlled switching and isolation within medium-voltage distribution systems. Typical applications may include plant power distribution, utility-connected installations, and industrial electrical rooms where equipment between 1 kV and 38 kV must be coordinated with the broader system. It is especially relevant when engineers, specifiers, and purchasers need a clear basis for selecting switchgear that fits the intended operating environment.
Why is C37.20.3-2013 important?
C37.20.3-2013 matters because it supports more consistent design, specification, and acceptance of enclosed interrupter switchgear. In medium-voltage applications, clear requirements help reduce ambiguity around ratings, performance, and safety-related expectations. That can improve compliance efforts, simplify procurement, and support testing and verification during project delivery. For organizations working with power equipment, the standard also helps establish a common technical basis for comparing products and managing risk.
