Bussmann FRS-R-150 Class RK5 Dual Element Time Delay Fuse 150A 600V

The Bussmann FRS-R-150 is a 150-amp, 600-volt AC Class RK5 dual element time delay fuse designed for reliable overcurrent protection in commercial and industrial electrical systems. This high-interrupting capacity fuse provides superior circuit protection for motors, transformers, and other equipment subject to high inrush currents.

Key Features:

• 150 amp current rating with 600 volt AC capacity
• Class RK5 design with 200,000 AIC interrupting rating at 600V
• Dual element time delay construction allows temporary overloads while protecting against short circuits
• Current-limiting design helps reduce potential damage to downstream equipment
• Rejecting blade design prevents replacement with lower interrupting capacity fuses
• UL Listed and meets NEC requirements for branch circuit protection

The FRS-R series features a time delay element that permits harmless temporary overloads associated with motor starting and transformer inrush, while the short circuit element provides fast response to fault conditions. Ideal for motor circuits, transformer primaries, feeder circuits, and other applications requiring reliable time delay protection.
