About This Item
PC37.011/D14 is a technical standard for voltage circuit breakers, framed as a revision of C37.011-1979 and noted as superseded by C37.011-2005. It is relevant to power, energy, and industry applications where breaker design and performance expectations need a defined reference. For engineers, purchasers, and compliance teams, this document helps identify the requirements associated with a specific generation of circuit breaker practice and supports more consistent specification review.
PC37.011/D14 overview
This standard addresses the technical context of voltage circuit breakers, with attention to the requirements that guide design, ratings, and performance expectations for electrical interruption equipment. As a revision document, PC37.011/D14 is useful for understanding how earlier breaker requirements were organized before later superseding editions. In procurement and engineering workflows, it can serve as a reference point when comparing equipment, reviewing legacy documentation, or tracing the basis for breaker-related compliance decisions in power systems.
Typical use cases
PC37.011/D14 is commonly relevant when working with medium- or higher-voltage circuit breaker specifications in power distribution, industrial electrical infrastructure, and utility-oriented equipment review. It may be used to assess breaker characteristics for switchgear assemblies, maintenance records, and legacy system documentation. Teams evaluating replacement equipment or comparing historical design expectations can use the standard to align technical requirements with the intended operating environment and the broader needs of power and energy applications.
Why this standard matters
This standard matters because voltage circuit breakers play a direct role in interruption, protection, and system reliability. Clear requirements help reduce ambiguity in design, testing, and procurement, especially when equipment must match established electrical practice. PC37.011/D14 also supports traceability for older breaker specifications, which can be important when reviewing installed assets, validating documentation, or managing legacy inventories. Using a defined standard can improve consistency and lower risk in engineering decisions.
