Built for installations where exact specification matching matters, this unit shines in maintenance, retrofit, and replacement tasks where you need reliable compatibility with Eaton panels.\u003c\/p\u003e \u003ch3\u003eKey specifications\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eAmperage:\u003c\/strong\u003e 125 A\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003ePoles:\u003c\/strong\u003e 3-Pole\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eVoltage rating:\u003c\/strong\u003e 600 V\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eReference:\u003c\/strong\u003e Part number KDC3125 is your best match for compatibility\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eWhy this breaker excels in real-world service\u003c\/h3\u003e\n\u003cp\u003eWhen you're maintaining an electrical distribution system, a precise fit matters as much as protection. The KDC3125 uses Eaton's proven design to ensure simultaneous disconnection of all live conductors in a 3-phase circuit, reducing exposure during maintenance. Its 125A rating makes it suitable for load centers and panels that require robust control of medium-sized industrial loads without overtripping during startups.\u003c\/p\u003e \u003ch3\u003eFit and compatibility you can trust\u003c\/h3\u003e\n\u003cp\u003eBefore ordering, verify fit and ratings against your equipment list. The KDC3125 is specifically intended as a direct-match replacement or retrofit where the part number lines up with Eaton's catalog. Using the correct part number helps ensure proper trip characteristics, mounting, and electrical clearances in your panelboard or distribution panel.\u003c\/p\u003e \u003ch3\u003eIdeal applications\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003eMaintenance and retrofit projects in commercial or light industrial electrical systems\u003c\/li\u003e \u003cli\u003eReplacement in panels that require a 125A, 3-pole, 600V protection device\u003c\/li\u003e \u003cli\u003eSpare parts inventory for preventive maintenance programs\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003ePractical tips for installers\u003c\/h3\u003e\n\u003cp\u003eKeep a verified stock of KDC3125 units where you support three-phase distribution equipment. When replacing, confirm panel door labeling, mounting chassis compatibility, and conductor sizing to match the breaker’s 125A rating and 600V maximum. With correct installation, you’ll maintain reliable protection while minimizing downtime.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Eaton","offers":[{"title":"Default Title","offer_id":46427386020002,"sku":"KDC3125","price":44457.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/8094\/6850\/files\/eaton-kdc3125-circuit-breaker-125a-3-pole-600v-826.webp?v=1789713610","url":"https:\/\/www.ampstate.com\/products\/eaton-kdc3125-circuit-breaker","provider":"Ampstate Electric Corporation","version":"1.0","type":"link"}
