LOT OF 3 GOULD TRS125R CLASS RK5 TRI-ONIC TIME-DELAY FUSE T269108

The Gould TRS125R (now manufactured under the Mersen/Ferraz Shawmut brand) is a high-performance Class RK5 Tri-Onic Time-Delay Fuse rated for 125 Amps at 600V AC/DC. This dual-element, current-limiting fuse is a critical safety component specifically engineered to provide superior overcurrent protection for motor circuits, transformers, and service entrance equipment where high inrush currents are common. Unlike standard fuses, the TRS125R features a 10-second time-delay at 500% of its rating, effectively eliminating "nuisance blowing" during equipment startup while maintaining a massive 200,000 Amp interrupting rating (AIC) to protect sensitive downstream components from catastrophic short-circuit damage.
