About This Item
19-1943 is the standard titled AIEE Standards for Alternating Current Power Circuit Breakers, issued in English for engineers working with power, energy, and industrial electrical systems. It addresses the technical expectations for alternating current power circuit breakers, helping define how these devices are designed, rated, and evaluated for dependable operation. For procurement, specification, and historical reference, 19-1943 supports more consistent selection and comparison of breaker equipment in AC power applications.
19-1943 overview
This technical document focuses on alternating current power circuit breakers, a core component in electrical distribution and protection. As an AIEE standard, 19-1943 is relevant to the performance and engineering criteria used to describe breaker capabilities in power circuits. It likely serves as a reference for understanding ratings, operating characteristics, and related requirements that help align equipment expectations across design and testing activities. Its inactive status indicates it is mainly of archival or reference value today.
Typical use cases
19-1943 may be used when reviewing historical specifications for AC power circuit breakers in substations, switchgear assemblies, utility distribution equipment, and industrial power systems. It can also support comparison of legacy breaker documentation during maintenance planning, replacement work, or engineering reviews. In practice, the standard is useful where consistent terminology and technical criteria matter for circuit interruption, system protection, and equipment compatibility within power and energy applications.
Why this standard matters
Standards like 19-1943 matter because circuit breakers play a direct role in system protection, fault interruption, and operational safety. Clear requirements help reduce ambiguity in design choices, testing approaches, and procurement decisions for AC power equipment. For organizations handling older electrical assets, the standard can provide a dependable reference point for evaluating legacy hardware and maintaining consistency in documentation. That helps lower risk and supports more controlled engineering decisions.
