Cooper Bussmann FRN Series 40 Amp Brass Time-Delay Cartridge Fuses (2-Pack)

The Bussmann series BP-FRN-R-40 is an energy-efficient, dual-element, current limiting, time-delay Class RK5 fuse pack (2-pack) from the FUSETRON line. Its design offers optimal time-delay protection for equipment like power panelboards, motor control centers, and safety switches. Dual-element fuses separate overload and short-circuit protection, allowing inrush currents without blowing. This time-delay feature supports temporary overloads common during motor or transformer startups, reducing unnecessary fuse replacements. Time-delay - 10 seconds (minimum) at 500% of rated current. These fuse cartridges are UL- and CSA Listed for safety.

• Brass element RK5 fuse with superior overload capabilities
