The 133100R4 variant carries a 65E rating and is designed to be replaced after a fuse operation to restore protection without removing the entire SM‑5 assembly. When used with SM‑5 holders, this refill helps protect critical equipment such as transformers, capacitor banks, and feeder cables in outdoor installations, supporting S\u0026amp;C's SM power fuse protection scheme. It is one of several SM‑5 refill ratings offered by S\u0026amp;C, part of a family that includes related part numbers like 132100R4 and 263100R4 to accommodate different protection requirements. The refill unit is installed onto the SM‑5 spring‑and‑cable assembly and reassembled to restore the current path and coordination with the corresponding fuse links. As with other SM‑5 components, it is manufactured by S\u0026amp;C Electric Company and is used in substations to maintain reliable feeder protection and minimize downtime after a fault event.\u003c\/p\u003e\u003c\/div\u003e","brand":"S\u0026C","offers":[{"title":"New","offer_id":46284106563818,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-022.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/s-c-electric-company-133100r4-sm-5-fuse-refill","provider":"GTG Hardware","version":"1.0","type":"link"}
