This 225A, 2-pole design is purpose-built for maintenance, retrofit, and replacement projects where exact GE compatibility is essential. When you need a seamless fit in GE panels and feeders, MB512 is engineered to keep electrical systems safe and compliant while delivering dependable performance in demanding environments.\u003c\/p\u003e \u003ch3\u003eKey specifications\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eAmperage:\u003c\/strong\u003e 225A\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003ePoles:\u003c\/strong\u003e 2-Pole\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eVoltage:\u003c\/strong\u003e 240V\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003ePart number:\u003c\/strong\u003e MB512\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eWhy choose the GE MB512\u003c\/h3\u003e\n\u003cp\u003eThis isn’t a generic replacement. The MB512 is designed to align precisely with GE panels and equipment, reducing installation guesswork and ensuring reliable grid protection. A two-pole configuration provides coordinated disconnection on both legs of a 240V circuit, improving safety and simplifying service work. The 225A rating is tuned for larger feeders found in commercial and light industrial settings, offering robust protection without unnecessary nuisance trips in high-demand applications.\u003c\/p\u003e \u003ch3\u003eIdeal use cases\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003eMaintenance and service work on GE electrical panels that require a 225A, 2-pole, 240V breaker\u003c\/li\u003e \u003cli\u003eRetrofits to upgrade existing feeders to a higher-capacity, GE-compatible solution\u003c\/li\u003e \u003cli\u003eReplacement for failed or aging MB512 units to minimize downtime\u003c\/li\u003e \u003cli\u003eNew installations in facilities where GE part-numbered components ensure straightforward compatibility\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003ePractical guidance\u003c\/h3\u003e\n\u003cp\u003eBefore ordering, verify fit and ratings against your panel’s documentation. The MB512 part number is the most reliable reference for compatibility, helping you avoid mismatches and ensure a smooth, compliant installation. If your system relies on GE-specific breakers, choosing MB512 means fewer surprises at hookup and faster project turnaround.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e Confirm the application matches a 240V, 2-pole configuration and that the 225A rating aligns with the protection needs of the circuit. This ensures optimal safety, performance, and longevity of your electrical infrastructure.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"General Electric","offers":[{"title":"Default Title","offer_id":46426265157794,"sku":"MB512","price":3122.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/8094\/6850\/files\/general-electric-mb512-circuit-breaker-225a-2-pole-240v-833.webp?v=1789546434","url":"https:\/\/www.ampstate.com\/products\/general-electric-mb512-circuit-breaker","provider":"Ampstate Electric Corporation","version":"1.0","type":"link"}
