Bussmann FRN-R-100 100 Amp Dual Class RK5 Non-Indicating Fuse, Blade End x Blade End, 250 Vac

Description

Features

• Engineered with an innovative dual-element construction, the FRN-R-100 provides a minimum of 10 seconds of time-delay at 500% of its 100-amp rated current. This allows it to easily absorb temporary surge currents and transient motor inrush spikes without blowing, eliminating frustrating machinery downtime while maintaining steadfast overcurrent protection.
• Featuring an exceptional interrupting rating of 200,000 Amps AC RMS Symmetrical at 250V, this FusetronTM cartridge fuse safely clears catastrophic short circuits. Its heavy-duty current-limiting performance suppresses dangerous electrical energy before it can damage downstream panel boards, branch circuits, or valuable manufacturing equipment.
• This dual-element fuse delivers highly sensitive low-level overload protection, closely mirroring the thermal limits of industrial motors. By stepping in to clear sustained overcurrent conditions, it effectively safeguards your machinery against destructive motor burnout caused by single-phasing on three-phase power systems or mechanical overloads.
• Offering robust multi-system compatibility, the FRN-R-100 carries a certified DC rating of 125VDC with a 20,000 Amp interrupting capacity alongside its 250VAC capability. This makes it an ideal, cost-effective cross-over solution for heavy-duty commercial DC distribution networks, transit systems, and industrial battery banks requiring code-compliant circuit protection.
