About This Item
C37.12-1952 is the ASA American Standard Guide Specifications for Alternating Current Power Circuit Breakers, a technical document focused on the design and specification of AC power circuit breakers. It addresses the equipment used in power, energy, and related industrial applications, where consistent ratings and construction guidance are important. For engineers and buyers working with switching and protection equipment, C37.12-1952 helps define a clearer basis for selection, comparison, and compliance.
Overview of C37.12-1952
This standard provides guide specifications for alternating current power circuit breakers, supporting technical consistency in equipment intended for power system service. In practice, that means attention to construction, performance expectations, ratings, and related engineering details that affect how a breaker is specified and evaluated. As a superseded standard, C37.12-1952 is most useful as a reference for legacy documentation, historical equipment records, and understanding the technical basis used for earlier AC power circuit breaker requirements.
Typical use cases
C37.12-1952 is relevant when reviewing or specifying AC power circuit breakers for electrical distribution, industrial power systems, and utility-oriented installations. It may also be used when checking legacy procurement documents, comparing older breaker designs, or interpreting technical files for installed equipment. The guide specifications are especially useful where circuit breaker ratings, operating performance, and construction details need to align with established power engineering practice.
Why it matters
For power and energy equipment, clear specifications help reduce ambiguity in procurement, engineering review, and maintenance planning. C37.12-1952 supports that process by giving a structured reference point for alternating current power circuit breakers, which can improve consistency across design and testing discussions. Even though it is superseded, it can still help teams evaluate older installations, confirm historical compliance expectations, and manage risk when working with legacy switching equipment.
