Part of the Siemens G3B family, this model (G3B020) delivers consistent overload and short-circuit interruption to keep panels and equipment safe.\u003c\/p\u003e \u003cp\u003eKey reasons to choose the G3B020 include its robust three-pole design, a 20 A current rating, and 240 V compatibility, making it ideal for 3-phase distribution rooms, motors, and other equipment that run on a 240V feed. Its compact form fits standard electrical panels that accommodate Siemens’ G3B-series breakers, simplifying replacements and upgrades.\u003c\/p\u003e \u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eCurrent rating:\u003c\/strong\u003e 20 A\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003ePoles:\u003c\/strong\u003e 3\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eVoltage rating:\u003c\/strong\u003e 240 V\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003ePart number:\u003c\/strong\u003e G3B020\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eConfiguration:\u003c\/strong\u003e 3-pole protection for 240V circuits\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003eWhere you’ll use it: in commercial or light-industrial environments with three-phase equipment, such as compressors, pumps, conveyors, or HVAC subsystems, as well as panelboards that feed 240V loads. The G3B020 provides dependable protection across all three conductors, helping prevent damage from overloads and short circuits and reducing downtime.\u003c\/p\u003e \u003cp\u003eWhy it stands out: Siemens’ G3B line is built for durability and predictable performance in real-world installations. The G3B020 is designed for straightforward installation and serviceability, so replacements or upgrades in existing Siemens panel setups are hassle-free, with consistent performance across temperature ranges and duty cycles common in everyday electrical rooms.\u003c\/p\u003e \u003cp\u003ePractical tips: ensure your panel is rated for Siemens G3B-series breakers and that wiring connections are tightened to manufacturer specs. Always install by a qualified electrician and follow local electrical codes. If you’re upgrading from a different breaker family, verify panel compatibility and trip characteristics to ensure seamless integration with your existing protection scheme.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"Default Title","offer_id":46423272816802,"sku":"G3B020","price":510.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/8094\/6850\/files\/master_generic_229276d9-908d-46df-93e5-6fe31866e0ff.png?v=1765492975","url":"https:\/\/www.ampstate.com\/products\/siemens-g3b020","provider":"Ampstate Electric Corporation","version":"1.0","type":"link"}
