This refill unit is specified for use with SM fuse assemblies and SM-4 holders, matching S\u0026amp;C’s published guidance on coordinating refill components and the replacement of unblown refill units in field service. Common applications include outdoor substations and distribution feeders where 34.5 kV equipment protection requires precise current-coordination to minimize unnecessary outages, making the 124150R3 a targeted choice for engineers implementing S\u0026amp;C SM-4 fault-protection schemes. These refill units form part of a broader family of SM-4 compatible components designed to enable coordinated protection across a range of voltage and current ratings, ensuring reliability in suburban and utility-scale distribution networks.\u003c\/p\u003e\u003c\/div\u003e","brand":"S","offers":[{"title":"New","offer_id":46284110069994,"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-124150r3-refill-unit-kv-34-5-amp-100e-tcc-no-153-4","provider":"GTG Hardware","version":"1.0","type":"link"}
