Zamak 7 sounds like something that you’re going to find in a high-tech lab or maybe even a futuristic space travel alloy. But in reality, it’s a special zinc-based metal with very good strength, good durability, and easy to cast. Zamak 7 is used in all sorts of applications, from automotive parts to intricate consumer […]
Recently, many customers have been asking the YiZao customer service team about the key parameters of surge protectors, looking to review the specific specifications of YiZao surge protectors. It seems that there is still some uncertainty regarding the parameters indicated on surge protectors. In this article, the YiZao editor will provide a detailed introduction to […]
Abstract: With the increasing demand for electrical equipment and technological advancements, modular contactors are emerging as a viable option to replace traditional contactors. This study explores the advantages of modular contactors, their performance in practical applications, and discusses the key challenges in their technical implementation and development trends. Introduction: Contactors are vital components of electrical […]
3 Terms and definitions For the purposes of this document, the following terms and definitions apply. ISO and IEC maintain terminology databases for use in standardization at the following 3.1 General terms 3.1.1 overcurrent current exceeding the rated current [SOURCE: IEC 60050-441:1984, 441-11-06] 3.1.2 short-circuit accidental or intentional conductive path between two or more conductive […]
Analysis of Overheating Faults in AC Contactor Main Contacts: Excessive current flow through the main contacts: The contacts of any electrical device must operate within their rated current values to avoid overheating. Excessive current flow can be caused by high or low system voltage, overload operation of electrical equipment, improper selection of contactor capacity, or […]
