About This Item
C37.04-1999/Cor 1-2009 is a corrigendum to the voltage circuit breakers standard, addressing corrections and clarifications for engineering use in power, energy, and industry applications. It helps readers apply the technical requirements more accurately when evaluating circuit breaker design, ratings, and related compliance details. For organizations working with medium- and high-voltage equipment, this document supports more consistent interpretation of the underlying standard and reduces the risk of specification errors.
C37.04-1999/Cor 1-2009 overview
This technical corrigendum supplements C37.04 by refining the published text for voltage circuit breakers. In practice, that means it is used alongside the main standard to improve the accuracy of requirements that affect equipment selection, performance assessment, and documentation. C37.04-1999/Cor 1-2009 is relevant where precise wording matters for engineering review, procurement language, and conformance checking in power-system applications.
Typical use cases
Professionals may consult C37.04-1999/Cor 1-2009 when reviewing specifications for voltage circuit breakers used in substations, industrial power distribution, and utility-related equipment programs. It is useful during design verification, bid evaluation, and testing coordination where corrected standard text can influence ratings, operating characteristics, or acceptance criteria. The document is also helpful for maintenance teams and engineers comparing legacy requirements against current project documentation.
Why this standard matters
Even small corrections in a standards document can affect compliance decisions, test interpretation, and procurement accuracy. C37.04-1999/Cor 1-2009 matters because voltage circuit breakers must be specified and evaluated with care to support safe and reliable power-system operation. Using the corrigendum alongside the base standard can help reduce ambiguity, improve consistency across project documents, and support better technical communication between manufacturers, engineers, and buyers.
