Ferraz Shawmut TR200R Smart Spot Tri-Onic Time-Delay Fuse is a 200 A, 250 VAC slow-blow device from the Tri-Onic family, designed to protect electrical circuits from short-term overloads while accommodating brief current surges. The time-delay (Smart Spot) construction provides reliable protection by delaying interruption for transient faults, helping maintain service during startup or short-duration overloads. The TR200R is RK5-compatible, making it suitable for installations that specify RK5 fuse blocks or assemblies.
