Bussman Fusetron Dual Element Time Delay Fuse (MPN: FRS-R-35)

Advanced protection with energy efficient Class RK5 design for motors and transformers.

The Bussman Fusetron Dual Element Time Delay Fuse is engineered for advanced protection in electrical circuits, particularly for motors and transformers. This Class RK5 fuse features a dual-element design that provides superior time delay performance, allowing for closer sizing and enhanced protection against overloads and short circuits. With a 35 Amp rating and a robust interrupting capacity of 200 Kiloampere at 600 Volt AC, this fuse is suitable for a wide range of applications.

The time-delay feature of this fuse allows for a minimum delay of 10 seconds at 500 percent of the rated current, making it effective in circuits that experience temporary motor overloads and surge currents. This capability enables the use of smaller fuse amp ratings compared to non-time delay fuses, resulting in cost savings and improved efficiency. Additionally, the Bussman Fusetron provides essential protection against ground faults and helps prevent motor burnout when properly sized.

Designed for reliability, this fuse is classified as Class RK5 and is marine rated, ensuring it meets the demands of various industrial environments. The dual-element feature not only enhances performance but also contributes to the overall safety and longevity of electrical systems by limiting current and protecting downstream components from high fault currents.
