Bussmann FUSETRON FRN-R-100 Class RK5 Time Delay Fuse

The Bussmann FUSETRON FRN-R-100 is a Class RK5 time delay fuse designed for reliable overcurrent protection in electrical circuits. This fuse is engineered to provide both overload and short-circuit protection, making it ideal for a wide range of industrial applications. The history of Bussmann fuses dates back to the early 20th century when the company pioneered fuse technology and electrical safety. Over the decades, Bussmann has maintained its reputation for quality and innovation, leading to the development of the FUSETRON series, which includes the FRN-R-100 model. This specific fuse is rated at 100 Amperes and designed for use in circuits with a voltage of up to 250 Volts. The time delay feature allows the fuse to tolerate temporary overload conditions without blowing, which is particularly important for motors and transformers that may experience inrush currents at startup. The applications of the FRN-R-100 are diverse, spanning across various industries including manufacturing, construction, and commercial sectors. It is commonly used in panelboards, motor control applications, and industrial machinery where equipment reliability is crucial. Unique features of the FRN-R-100 include its dual element design, which provides an added layer of protection by distinguishing between temporary and sustained overloads. Additionally, the fuse is designed for easy installation and replacement, with a physical size that fits standard fuse holders. This ensures minimal downtime in case of a fault, contributing to overall operational efficiency.
