FRN-R-7-1/2 Bussmann 250 Volt 7-1/2 Amp Fusetron Dual-Element Time Delay Fuse ( Equal to TR-R, FLNR, ECNR )

Current-Limiting Dual-Element Time-Delay 250 VAC (or less) Class RK5 Fuse

Features:

• Helps protect motors against burnout from overloads.
• Provides motor overload, ground fault and short-circuit protection.
• Separate overload and short-circuit elements provide time delay for sizing as close as 125% of motor FLA
• 2:1 selective coordination amp ratio (within the Cooper Bussmann RK5 fuse family) prevents overcurrent events from opening upstream Fusetron fuses
