The YS121 designation identifies this specific two-pole configuration within the Siemens Furnas magnetic contactor family, a class of devices that uses an electromagnetic coil to move the contacts and switch connections without manual operation. With two poles, the unit can interrupt or feed two separate conductors, enabling single-device switching of two lines in a 220–440V system. When the coil is energized, the magnetic field pulls in the contacts to complete the circuit; when the coil is de-energized, springs separate the contacts to interrupt current, providing rapid and reliable isolation of the connected load. This description captures the core electrical interface: manufacturer Siemens Furnas, device type magnetic contactor, model YS121, pole count 2, and voltage range 220–440V, establishing its suitability for standard AC installations within that voltage window.\u003c\/p\u003e\u003c\/div\u003e","brand":"Furnas","offers":[{"title":"New","offer_id":51691161583918,"sku":null,"price":109.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_85ae77ee-27eb-43d4-884d-ee8c06b939e2.jpg?v=1769881921","url":"https:\/\/plgautomation.com\/products\/siemens-furnas-ys121-magnetic-contactor-2-pole-220-440v","provider":"PLG Automation ","version":"1.0","type":"link"}
