This JXD‑series MCCB uses a thermal‑magnetic trip mechanism with a non‑interchangeable trip unit and is rated for ambient operation up to 40°C, ensuring predictable tripping under real‑world conditions. With a 25 kA short‑circuit rating at 600 V, it is designed to interrupt fault currents safely in standard 600 V distribution panels, switchboards, and feeders. As part of Siemens' Sentron family, the JXD62B300 is intended for use in panel configurations that specify the JXD\/JD molded‑case breakers, providing compact protection for branch circuits and motor loads while fitting typical Siemens busbar layouts and terminal schemes.\u003c\/p\u003e\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46269110616298,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-019.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/siemens-sentron-jxd62b300-circuit-breaker-300-amp-600-v-2-pole","provider":"GTG Hardware","version":"1.0","type":"link"}
