ACB

ACB is an acronym that can refer to several distinct concepts across different fields, so its meaning depends on context. It is commonly used in electrical engineering, sports, and biochemistry, among other areas.

In electrical engineering, ACB stands for air circuit breaker. An air circuit breaker is a protective device used to interrupt current in AC electrical systems, typically in low- to medium-voltage installations. It operates by extinguishing the electrical arc in air and is designed to interrupt fault currents to protect equipment and personnel. ACBs are often installed in distribution boards or switchgear and are selected for higher current ratings than standard molded-case breakers.

In professional basketball in Spain, ACB refers to the Asociación de Clubes de Baloncesto. This governing body administers the top-tier league system, most notably the Liga ACB, which is regarded as one of Europe’s premier basketball competitions. The organization coordinates competition schedules, rules, and national and international participation for its member clubs.

In biochemistry, ACB can denote the acyl-CoA binding protein, often abbreviated ACBP in literature. This small cytosolic protein binds long-chain acyl-CoA esters with high affinity and participates in lipid metabolism and intracellular lipid trafficking. The ACBP family is conserved across eukaryotes and has multiple isoforms that contribute to the regulation of fatty acid metabolism and related cellular processes.

These uses illustrate how ACB functions as a multi-domain acronym, with the intended meaning clarified by the surrounding subject matter.
