It carries a 175E (175 A RMS) current rating and is specified for 14.4 kV nominal operation with a maximum of 17.0 kV, making it suitable for 14.4 kV-class distribution feeders and switchgear where compact, cartridge-style protection is required. This AK variant is part of the SMU-40 family used with SM-40 mountings and can accommodate S\u0026amp;C SMD-40 power fuses within compatible gear, enabling coordinated protection in distribution substations. Time-current characteristics for SMU-40 fuse units are published by S\u0026amp;C and include curves appropriate for the 175A rating (e.g., 175-2-2), supporting selective coordination with downstream devices. Catalog number 832175 therefore corresponds to a 14.4 kV\/175A configuration in the SMU-40 lineup, one of several SKUs that align with the SMU-40’s modular, replaceable-fuse design. SMU-40 fuse units are designed for installation or removal from their mountings via a universal pole with S\u0026amp;C Large Clamp, aiding field service and quick replacement in installed gear.\u003c\/p\u003e\u003c\/div\u003e","brand":"S","offers":[{"title":"New","offer_id":46284110495978,"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-832175-smu-40-fuse-unit-14-4-kv-175e-amps-ak","provider":"GTG Hardware","version":"1.0","type":"link"}
