{"product_id":"industrial-qfl125-circuit-breaker","title":"Industrial QFL125 Circuit Breaker","description":"\u003cdiv\u003e\u003cp\u003eIndustrial QFL125 Circuit Breaker is a three‑pole, 125‑amp unit in the QFL family, designed for legacy electrical panels branded Zinsco, GTE Sylvania, and Challenger. As a replacement breaker, it supports three‑pole 125A circuits in older industrial and commercial installations that used the QFL style and the cross‑brand lineage that includes Zinsco, Sylvania, Challenger, and GTE Sylvania. The QFL family is documented as a compatible replacement option for older panels in which QFL‑type breakers were standard, making this unit a recognized solution for servicing aging equipment built around that platform. Typical applications include distribution panels in facilities with three‑phase power where 125A protection is required, with the breaker’s three‑pole configuration safeguarding all three conductors in the circuit. This part reflects the historical cross‑brand evolution of Zinsco\/Challenger\/GTE Sylvania breakers and positions the QFL125 as a genuine replacement for legacy installations that use QFL‑style mechanisms.\u003c\/p\u003e\u003c\/div\u003e","brand":"Challenger","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51677930422574,"sku":null,"price":434.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_e3841be8-a3d6-4152-81eb-be9fc7ea2311.jpg?v=1769569629","url":"https:\/\/plgautomation.com\/products\/industrial-qfl125-circuit-breaker","provider":"PLG Automation ","version":"1.0","type":"link"}
