Facilities with substantial three-phase loads—manufacturing floors, data centers, warehouse complexes, and large commercial spaces—will benefit from a dedicated 400 A main breaker that protects feeders and downstream circuits. If you’re upgrading an aging panel or conducting routine maintenance, this exact part number (SGLB36CB0400) ensures compatibility and preserves the integrity of your GE electrical system.\u003c\/p\u003e \u003cp\u003eWhy choose this GE breaker? It’s a high-current, three-pole solution designed to integrate cleanly into GE-based distributions, reducing the risk of incompatible replacements and downtime. Its 600 V rating makes it suitable for industrial environments where higher-voltage service is common, while the 400 A capacity supports robust load management without frequent nuisance tripping when demand is steady but controlled.\u003c\/p\u003e \u003cp\u003ePractical tips: confirm your panel’s labeling matches 600 V\/400 A capability, replace only with the exact part number to maintain system integrity, and schedule professional testing after installation to verify proper trip operation. This GE SGLB36CB0400 breaker is a precise, reliable choice when you need strong, dependable protection for a three-phase, high-current electrical feed.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"General Electric","offers":[{"title":"Default Title","offer_id":46423069917346,"sku":"SGLB36CB0400","price":510.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/8094\/6850\/files\/general-electric-sglb36cb0400-400a-3-pole-600-v-circuit-breaker-270.webp?v=1789267091","url":"https:\/\/www.ampstate.com\/products\/general-electric-sglb36cb0400","provider":"Ampstate Electric Corporation","version":"1.0","type":"link"}
