Built for maintenance, retrofit, and replacement work, this unit helps keep critical equipment safe while aligning with your existing Siemens panel architecture.\u003c\/p\u003e \u003cp\u003eKey advantages come from using the exact part within the Siemens QJ family: consistent electrical characteristics, straightforward field replacement, and a mounting footprint designed to fit compatible panels. When exact specs are required, choosing the QJ23B100L ensures your system maintains its intended protection profile with minimal downtime.\u003c\/p\u003e \u003cul\u003e \u003cli\u003e\n\u003cstrong\u003ePoles:\u003c\/strong\u003e 3-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 QJ23B100L\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eRecommended use:\u003c\/strong\u003e Maintenance, retrofit, or replacement where exact specifications are required\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eCompatibility note:\u003c\/strong\u003e The part number is the best reference for compatibility; confirm fit and ratings before ordering\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003eWhy this matters: using the precise Siemens QJ23B100L part preserves system electrical characteristics and physical fit, reducing installation guesswork. It’s especially valuable when upgrading 3-phase distribution paths or restoring a failed unit in Siemens-based equipment, helping you avoid mismatched components and unnecessary downtime.\u003c\/p\u003e \u003cp\u003eIdeal scenarios include a facilities team upgrading a 3-phase service in a warehouse, an industrial maintenance crew replacing worn breakers in a Siemens switchboard, or a equipment manager stocking spares for routine panel servicing. The 3-pole, 240V configuration is tailored for protecting 3-phase circuits common in commercial and light-industrial environments.\u003c\/p\u003e \u003cp\u003ePractical installation tips: de-energize the system before handling; verify that the panel documentation supports 3-pole, 240V protection and that the QJ series is appropriate for your panel. Keep the part number QJ23B100L handy for future ordering, and store replacements in a labeled, readily accessible location.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"Default Title","offer_id":46425634603170,"sku":"QJ23B100L","price":3334.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/8094\/6850\/files\/master_generic_a085eff1-75dd-47ee-b131-4c8df8f0489b.png?v=1765492976","url":"https:\/\/www.ampstate.com\/products\/siemens-qj23b100l-circuit-breaker","provider":"Ampstate Electric Corporation","version":"1.0","type":"link"}
