The SGLL3604L4X6 is purpose-built for high-current environments where reliable performance is non-negotiable—from motor drives and compressors to large HVAC units and distribution panels. With a 400 A rating, it’s suited for heavy-duty feeders and main protection in mid- to large-size installations, offering clear trip signals and swift fault clearance when anomalies occur.\u003c\/p\u003e \u003ch3\u003eIdeal applications and use cases\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003eIndustrial facilities and manufacturing lines with high-current motors\u003c\/li\u003e \u003cli\u003eCommercial electrical distribution panels powering large equipment\u003c\/li\u003e \u003cli\u003eData centers or server rooms with substantial, centralized power requirements\u003c\/li\u003e \u003cli\u003eElectrical service entrances and feeder circuits in facilities using three-phase 600 V systems\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eWhat makes this GE breaker stand out\u003c\/h3\u003e\n\u003cp\u003eUnlike smaller or single-phase devices, the SGLL3604L4X6 is tailored for demanding three-phase circuits, providing coordinated protection across all phases. Its 600 V rating accommodates many industrial and commercial electrical systems, while the 400 A capacity supports sizeable loads without frequent tripping. The result is steadier power delivery, minimized nuisance trips, and improved uptime for critical equipment.\u003c\/p\u003e \u003ch3\u003eInstallation and practical considerations\u003c\/h3\u003e\n\u003cp\u003eFor best results, install in compatible GE panels and connect according to electrical codes and safety standards. Verify your bus arrangement and conductor sizing align with the 400 A rating, and ensure that the enclosure and wiring methods comply with local regulations. If you’re upgrading from a lower-current device, plan for appropriate wiring upgrades and panel adjustments to accommodate the higher protection level and three-phase configuration.\u003c\/p\u003e \u003ch3\u003eFast, reliable protection you can trust\u003c\/h3\u003e\n\u003cp\u003eWith the General Electric SGLL3604L4X6, you’re choosing a purpose-built solution for safeguarding high-current, three-phase systems. It delivers decisive fault interruption, helping to prevent equipment damage, reduce downtime, and maintain safer, more efficient electrical operations across your facility.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"General Electric","offers":[{"title":"Default Title","offer_id":46423085842594,"sku":"SGLL3604L4X6","price":510.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/8094\/6850\/files\/general-electric-sgll3604l4x6-400a-3-pole-600-v-circuit-breaker-641.webp?v=1789268373","url":"https:\/\/www.ampstate.com\/products\/general-electric-sgll3604l4x6","provider":"Ampstate Electric Corporation","version":"1.0","type":"link"}
