This North American variant (US2: SHLD6B600LSI) carries UL 489 listing with an interrupting rating of 35 kA at 600 VAC, with higher ratings at lower voltages (100 kA at 240 VAC and 65 kA at 480 VAC) to accommodate different distribution architectures. The LSI trip function provides controlled coordination by allowing long‑time overload protection, short‑time interruption for faults, and an instantaneous response for severe faults, helping safeguard conductors, motors, and downstream devices in industrial power layouts. Built by Siemens for high‑current, three‑phase applications, the SHLD6B600LSI combines robust molded‑case construction with precise electronic protection, making it suitable for panelboards and distribution panels in demanding commercial and industrial environments.\u003c\/p\u003e\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"New","offer_id":46269151346922,"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-019.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/siemens-shld6b600lsi-three-phase-circuit-breaker","provider":"GTG Hardware","version":"1.0","type":"link"}
