The QC2020 model supports 50\/60 Hz operation and is described for use in 3-phase configurations. As a miniature circuit breaker, it automatically interrupts current in the event of an overload or short circuit to protect conductors and connected equipment in electrical panels or enclosures that require two-pole protection. The two-pole design ensures simultaneous disconnection of two conductors, providing straightforward protection for circuits specified as 2P 20 A in 3-phase systems. This part number identifies a distinct device within the Crouse-Hinds NSB lineup, intended where a 2P, 20 A MCB compatible with 50\/60 Hz service and 3-phase configurations is specified.\u003c\/p\u003e\u003c\/div\u003e","brand":"Crouse-Hinds","offers":[{"title":"New","offer_id":51679955190062,"sku":null,"price":38.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_8782c3c2-e2b2-4529-b174-a16894002002.jpg?v=1769616653","url":"https:\/\/plgautomation.com\/products\/crouse-hinds-nsb-qc2020-miniature-circuit-breaker","provider":"PLG Automation ","version":"1.0","type":"link"}
