It quickly detects overloads and short circuits, interrupting current flow to protect wiring, devices, and downstream equipment. This means less downtime, fewer repairs, and a safer overall installation. It’s particularly well-suited for spaces where panel space is at a premium and where 3-phase protection is required for motors, lighting, and general distribution.\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 JDB3150L\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 150 A\u003c\/li\u003e \u003cstrong\u003eVoltage Rating:\u003c\/strong\u003e 600 V \u003cli\u003e\n\u003cstrong\u003eNumber of Poles:\u003c\/strong\u003e 3\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\u003eNew installations in residential, commercial, and light industrial panels requiring 3-phase protection.\u003c\/li\u003e \u003cli\u003eUpgrading or replacing aging breakers in OEM-panel ecosystems where panel compatibility matters.\u003c\/li\u003e \u003cli\u003eFeeder protection for subpanels and distribution circuits within constrained electrical spaces.\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003ePractical tips and considerations\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003eVerify panelboard compatibility before installation to ensure correct bus alignment and trip characteristics.\u003c\/li\u003e \u003cli\u003eKeep spare units on hand for quick replacements in service panels and upgrade projects.\u003c\/li\u003e \u003cli\u003eFollow standard electrical torque specifications and manufacturer guidelines to maintain reliable performance and safe operation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Amp State","offers":[{"title":"Default Title","offer_id":46349620576418,"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_17879930-33c4-477e-93d4-e4ce1f4fc9a7.png?v=1764151639","url":"https:\/\/www.ampstate.com\/products\/eaton-jdb3150l-150a-600v-3-pole-circuit-breaker","provider":"Ampstate Electric Corporation","version":"1.0","type":"link"}
