The three-pole 480V configuration is well-suited to three-phase electrical systems common in commercial and light industrial environments, while the 100A rating provides targeted protection for upstream feeders and branch circuits without unnecessary disruptions. The integrated thermal-magnetic trip delivers predictable response to both overloads and short circuits, helping protect downstream equipment and extend service life.\u003c\/p\u003e \u003ch3\u003eWho benefits most\u003c\/h3\u003e\n\u003cp\u003eElectrical contractors performing panel upgrades or retrofit installations, facility managers maintaining distributed power in small to mid-size buildings, and installers working in residential, commercial, or light industrial projects that require a robust, field-installable breaker with proven OEM compatibility.\u003c\/p\u003e \u003ch3\u003ePractical considerations and tips\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003eConfirm compatibility with your existing Eaton panelboard or load center to ensure seamless operation and coordinated protection.\u003c\/li\u003e \u003cli\u003eUse in environments where vibration resistance is important to maintain a solid, long-lasting connection.\u003c\/li\u003e \u003cli\u003eRely on the thermal-magnetic trip for dependable protection across typical temperature ranges and fault conditions encountered in everyday installations.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Amp State","offers":[{"title":"Default Title","offer_id":46349555171490,"sku":null,"price":710.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/8094\/6850\/files\/eaton_breaker_and_panels_d7f4853a-61db-46aa-9da4-9d0c68d1700d.png?v=1764149553","url":"https:\/\/www.ampstate.com\/products\/eaton-ehd3100k-100a-480v-3-pole-bolt-on-circuit-breaker","provider":"Ampstate Electric Corporation","version":"1.0","type":"link"}
