Follow Siemens installation instructions for correct mounting and secure connections. If your protection scheme uses potential transformers for metering or coordination, configure sensing and tripping to align with upstream and downstream devices to achieve precise protection with minimal nuisance trips. Keeping a replacement unit on hand can reduce downtime during critical maintenance windows.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"Default Title","offer_id":46423583129762,"sku":"SCMD6B800LSIH","price":79610.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/8094\/6850\/files\/master_generic_229276d9-908d-46df-93e5-6fe31866e0ff.png?v=1765492975","url":"https:\/\/www.ampstate.com\/products\/siemens-scmd6b800lsih","provider":"Ampstate Electric Corporation","version":"1.0","type":"link"}
