Product description

The Bussmann FRS-R-30 is a high-performance Fusetron dual-element, time-delay fuse designed for the protection of motors and electrical distribution systems. Rated at 30 Amps and 600V, this Class RK5 fuse is a staple in industrial maintenance, providing an ideal balance between surge tolerance and fault protection. Its unique dual-element construction allows for a significant time delay during the high-current demands of equipment startup, preventing unnecessary downtime caused by blown fuses. At the same time, it provides fast-acting protection against short circuits, with a 200,000 Amp interrupting capacity that can safely isolate even the most severe electrical faults. The rejection-style design ensures that it cannot be replaced with a lower-rated class of fuse, maintaining the intended safety levels of the circuit.

Product highlights

• Fusetron Time-Delay: Incorporates a minimum 10-second delay at 5 times the rated current for smooth motor starts.
• High Fault Interruption: Capable of handling up to 200,000 Amps of fault current for maximum system safety.
• Energy Efficient: Low internal resistance reduces power consumption and heat generation within the fuse block.
• Rejection Style: Features a physical design that prevents the installation of non-rejection style or lower-class fuses.
• Broad Compatibility: AC and DC rated for use in a wide variety of commercial and industrial electrical panels.
