With an 80A rating across three poles and a 600V class, this unit is tailored for maintenance, retrofit, and replacement projects where precise compatibility matters. \u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eAmperage:\u003c\/strong\u003e 80 A\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003ePoles:\u003c\/strong\u003e 3-Pole\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eVoltage:\u003c\/strong\u003e 600 V\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Bolt-On\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e NGB3K080B\u003c\/li\u003e\n\u003c\/ul\u003e This circuit breaker serves as vital overcurrent protection for electrical distribution circuits in industrial and commercial settings. Its 3-pole configuration provides balanced protection across three phases, making it suitable for applications that require coordinated trip and stable performance in 600V systems. Where to use:\n- Maintenance, retrofit, or replacement in Siemens bolt-on panelboards and switchgear that specify the NGB family\n- Environments demanding durable, panel-compatible protection for multi-phase electrical distribution Compatibility and installation notes:\n- Confirm fit and ratings before ordering; the part number is the best reference for compatibility\n- Ensure the panel model and bus configuration match the NGB3K080B’s mounting and electrical requirements\n- Bolt-On mounting requires access to the panel interior and adherence to proper safety procedures during installation Why choose this Siemens breaker:\n- Precise 80A, 3-pole protection within a 600V class device designed for Siemens bolt-on panels\n- Streamlined retrofit and replacement workflow thanks to the exact NGB family alignment\n- Clear, part-number-based compatibility reduces guesswork in complex electrical environments Practical use cases:\n- Upgrading an aging distribution panel to restore balanced, three-phase protection for motors, compressors, and other loads\n- Replacing a mismatched breaker in a Siemens-equipped system to restore full protection without reconfiguring the panel\n- Specifying a ready-to-install bolt-on solution for service upgrades in new or existing installations that operate at up to 600V This description highlights how the Siemens NGB3K080B combines specific electrical ratings with a bolt-on mounting approach to meet the demands of professional maintenance, retrofit, and replacement projects. It’s a focused, compatible choice for engineers and electricians working within Siemens-equipped electrical distributions.\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"Default Title","offer_id":46426834501794,"sku":"NGB3K080B","price":3669.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/8094\/6850\/files\/siemens-ngb3k080b-circuit-breaker-80a-3-pole-600v-bolt-484.webp?v=1789630747","url":"https:\/\/www.ampstate.com\/products\/siemens-ngb3k080b-circuit-breaker","provider":"Ampstate Electric Corporation","version":"1.0","type":"link"}
