Fuseholders are a critical component of electronics systems, providing reliable overcurrent protection. The 972-A(BULK) is a fuseholder designed and manufactured by Magne-Tek (formerly known as Fuseco). This series of fuseholder is designed for heavy-duty use in industrial and commercial applications. In this article, we will look at the application field and working principle of the 972-A(BULK) fuseholder.

The 972-A(BULK) is an Amphenol fuseholder that is UL listed and CSA approved for temperatures from -55°C to +105°C. It is a flexible product that can be used in a variety of applications such as automotive, telecom, power, marine, and outdoor sites. The fuseholder is designed to be used with standard and miniature size fuse links and range from 5A to 30A. It also has a high-current AC application rating of up to 300A.

The 972-A(BULK) features a highly durable and reliable construction, consisting of a weather-resistant insulating base, a spring-loaded metal lid, an integral contact assembly, and a two-part ground lug. The contact assembly contains a series of silver-plated copper contacts, which are then connected to the ground lug to ensure optimal electrical contact and reliable protection from shorts. The spring-loaded lid ensures a tight grip on the fuse while at the same time allowing for easy insertion and replacement of the link.

The 972-A(BULK) also features a unique strain relief design which secures the base of the fuseholder to ensure a secure fit. The strain relief prevents the fuse from becoming loose, especially in high vibration environments. This adds to the fuseholders’ durability and reliability, allowing it to be used in harsh and demanding applications.

The fuseholder also includes a series of safety features. It is designed with a surface-mounted strain relief which provides mechanical support and electric insulation. It also includes a voltage rating of 600 VAC, an output rating of 15A and 30A, and an overvoltage rating of 1000V. Additionally, it includes an overcurrent thermal protection device to protect from overloads and current surges.

The working principle of the 972-A(BULK) is to provide reliable overcurrent protection to the circuit by providing a secure connection between the fuse and the circuit being protected. The fuseholder works by creating an air gap between the point of contact and the circuit, which allows excess current to flow through it, reducing the risk of overloads or short circuits and ensuring protected operation.

In conclusion, the 972-A(BULK) is a reliable and flexible fuseholder that is suitable for a wide range of applications, particularly in rugged and outdoor environments. It provides dependable overcurrent protection, and its highly durable construction ensures a secure fit and excellent electrical contact. Additionally, its safety features make it a great choice for ensuring high performance and long-lasting reliability.
