With its 3A rating and 480V capability, it serves as a reliable safeguard for critical distribution in panelboards and load centers.\u003c\/p\u003e \u003cp\u003ePractical use cases include protecting lighting runs, control circuits, or small equipment feeders in panelboards and load centers where a robust 3-pole, 480V breaker is required. In environments with vibration—such as mechanical rooms, manufacturing floors, or spaces with heavy equipment—the bolt-on configuration helps maintain a solid, low-resistance connection over time.\u003c\/p\u003e \u003cp\u003eCompared to other branch-circuit breakers, this model emphasizes long-term stability and straightforward service. The bolt-on mounting simplifies field replacement and reduces the risk of loose connections, translating to fewer unexpected trips and more uptime for essential systems.\u003c\/p\u003e \u003cp\u003eInstallation tips: pair this breaker with the correct OEM panelboard or loadcenter and follow the prescribed torque for bolt-on mounting to maintain the integrity of the bus connection and the thermal-magnetic trip performance.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Amp State","offers":[{"title":"Default Title","offer_id":46349613203618,"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_cb2f7c48-1908-4c4c-a7a4-b728c43f4b35.png?v=1764151353","url":"https:\/\/www.ampstate.com\/products\/eaton-hmcpe003a0x-3a-480v-3-pole-bolt-on-circuit-breaker","provider":"Ampstate Electric Corporation","version":"1.0","type":"link"}
