With a 20A rating and a 600V nominal voltage, it provides robust overcurrent and short-circuit protection where reliability matters most—in residential panels, commercial enclosures, and light industrial setups. The bolt-on mounting delivers a secure, vibration-resistant bus connection that maintains consistent electrical performance even in environments with movement or vibration.\u003c\/p\u003e \u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eSecure bolt-on mounting\u003c\/strong\u003e — creates a rigid, vibration-resistant bus connection for long-term reliability.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eThermal-magnetic trip unit\u003c\/strong\u003e — combines precise thermal overload protection with instantaneous magnetic trip for fast response to short circuits.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eOEM-compatible\u003c\/strong\u003e — designed to pair with matching Eaton OEM load centers and panelboards for seamless integration.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eVersatile applications\u003c\/strong\u003e — suitable for residential, commercial, and light industrial installations requiring dependable branch-circuit protection.\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eWhy this matters\u003c\/h3\u003e\n\u003cp\u003eIn panelboards and load centers, a solid connection and predictable protection are non-negotiable. The GBH3020’s bolt-on design minimizes the risk of loose connections that can drift under load or vibration, while the thermal-magnetic trip unit delivers stable, repeatable protection across a wide range of operating conditions. This means fewer nuisance trips and better protection for circuits feeding critical equipment, lighting, and outlets in both homes and business environments.\u003c\/p\u003e \u003ch3\u003eTechnical snapshot\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eManufacturer\u003c\/strong\u003e: Eaton\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003ePart Number\u003c\/strong\u003e: GBH3020\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Thermal-magnetic molded case circuit breaker\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eAmperage Rating\u003c\/strong\u003e: 20A\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 600V\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eNumber of Poles\u003c\/strong\u003e: 3\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eMounting Style\u003c\/strong\u003e: Bolt-on\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Branch circuit overcurrent and short-circuit protection\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eIdeal use cases\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003eResidential panelboards needing reliable 3-pole protection for 3-phase equipment or multi-wire branch circuits.\u003c\/li\u003e \u003cli\u003eCommercial enclosures where vibration resistance and secure mounting protect critical loads like lighting, outlets, and small motors.\u003c\/li\u003e \u003cli\u003eLight industrial panels requiring a robust, compatible 3-pole breaker that seamlessly matches OEM load centers.\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eInstallation and compatibility tips\u003c\/h3\u003e\n\u003cp\u003eChoose the GBH3020 when your panelboard or load center calls for a 3-pole, 20A breaker with bolt-on mounting. Ensure alignment with the OEM family for a clean, code-compliant installation. Because of its thermal-magnetic trip, this breaker reacts quickly to short circuits while preventing nuisance trips from brief overloads, making it well-suited for mixed-load environments with varying current demands.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Amp State","offers":[{"title":"Default Title","offer_id":46349588234402,"sku":null,"price":710.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/8094\/6850\/files\/eaton-gbh3020-20-a-600-v-3-pole-bolt-on-circuit-breaker-ampstate-780.webp?v=1788687785","url":"https:\/\/www.ampstate.com\/products\/eaton-gbh3020-20a-600v-3-pole-bolt-on-circuit-breaker","provider":"Ampstate Electric Corporation","version":"1.0","type":"link"}
