The 2-pole design ensures simultaneous disconnection of both live conductors on 240V circuits, helping to safeguard equipment and personnel during faults. The bolt-on configuration provides a solid, long-lasting installation well-suited to panels and enclosures that demand reliable retention under vibration or heavy load conditions.\u003c\/p\u003e \u003cp\u003eIdeal use cases include upgrades or refreshes in commercial and industrial electrical distributions where you must match a specific 350A, 240V, 2-pole profile. It’s also a practical choice for retrofitting older systems that require the JD22B350H form factor and rating, or for replacing worn or failed breakers with a like-for-like part.\u003c\/p\u003e \u003cp\u003eCompatibility and fit tip: always verify fit and ratings before ordering, and use the JD22B350H part number as the best reference for ensuring a correct match to your panel or control gear. When in doubt, cross-check the documentation for your equipment’s allowed interrupting capacity and mounting scheme to ensure seamless integration.\u003c\/p\u003e \u003cp\u003eIn real-world use, technicians turn to this Siemens bolt-on 350A 2-pole breaker to protect large feeders, motor circuits, and critical loads where precise 240V protection and a secure installation are non-negotiable. If you’re upgrading from a prior device or performing a targeted retrofit, the JD22B350H delivers the reliability and exact spec alignment you need for continued, safe operation.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"Default Title","offer_id":46427067875490,"sku":"JD22B350H","price":510.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/8094\/6850\/files\/siemens-jd22b350h-circuit-breaker-350a-2-pole-240v-bolt-642.webp?v=1789666929","url":"https:\/\/www.ampstate.com\/products\/siemens-jd22b350h-circuit-breaker","provider":"Ampstate Electric Corporation","version":"1.0","type":"link"}
