This part is identified by CJ2B200, making it the straightforward choice for maintenance, retrofit, or replacement projects where exact specs matter.\u003c\/p\u003e\n\u003cp\u003eWhy this matters: in high-demand electrical environments, you need a breaker you can trust to interrupt current cleanly and reliably when faults occur. The CJ2B200's 200 A rating handles heavy feeders, while the 2-pole design coordinates protection across paired hot legs for balanced shutdowns, helping minimize arc flash risks and equipment damage.\u003c\/p\u003e\n\u003cp\u003eBest reference for compatibility: use the CJ2B200 part number to confirm fit with Siemens panels and assemblies. Always verify the fit and ratings before ordering — this ensures the breaker matches your panel's screw terminals, trip characteristics, and enclosure type.\u003c\/p\u003e \u003ch3\u003eKey features and benefits\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e200 Amp capacity\u003c\/strong\u003e provides strong overcurrent protection for heavy-duty circuits and feeders.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e2-Pole configuration\u003c\/strong\u003e protects two hot conductors in tandem for common-trip operation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e600V maximum voltage rating\u003c\/strong\u003e suitable for commercial and industrial distribution equipment.\u003c\/li\u003e\n\u003cli\u003eSolid Siemens engineering ensures predictable trip performance and long service life in demanding environments.\u003c\/li\u003e\n\u003cli\u003eDesigned as a reliable replacement or retrofit part for existing CJ-series installations, reducing downtime during panel maintenance.\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eIdeal use cases\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMaintenance and retrofit projects where exact CJ2B200 specs are required to match existing gear.\u003c\/li\u003e\n\u003cli\u003eReplacement of aging or failed breakers in Siemens panels that require a 200A, 2-pole, 600V solution.\u003c\/li\u003e\n\u003cli\u003eFeeder protection for large circuits in commercial or light industrial panels, where clean isolation on fault is critical.\u003c\/li\u003e\n\u003cli\u003eNew builds that use Siemens CJ-series housing and seek a compatible, readily available 200A 2-pole option.\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eHow this compares and why it matters\u003c\/h3\u003e\n\u003cp\u003eCompared to generic, non-OEM options, the Siemens CJ2B200 offers guaranteed compatibility with Siemens enclosures, consistent trip curves, and readily available replacement parts. This minimizes the risk of fit issues, nuisance tripping, or warranty concerns, and simplifies procurement for technicians managing multi-panel ecosystems.\u003c\/p\u003e \u003cp\u003ePractical tips: before ordering, double-check the panel’s model and label for CJ2B200 compatibility, confirm the required voltage and current ratings, and ensure the enclosure and mounting style align with the 2-pole physical form. If you’re updating from an older style, consider pairing with a complete safety documentation update for peace of mind.\u003c\/p\u003e \u003cp\u003eTrusted choice for professionals who value precise specifications and reliable protection — the Siemens CJ2B200 circuit breaker helps you safeguard critical equipment and keep electrical systems running smoothly.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"Default Title","offer_id":46427179319458,"sku":"CJ2B200","price":510.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/8094\/6850\/files\/master_generic_a0994f42-7fad-49d1-911a-c2784022b8c9.png?v=1765492979","url":"https:\/\/www.ampstate.com\/products\/siemens-cj2b200-circuit-breaker","provider":"Ampstate Electric Corporation","version":"1.0","type":"link"}
