{"product_id":"abb-ovza-20-1-relay","title":"ABB OVZA-20-1 Relay","description":"\u003cdiv\u003e\u003cp\u003eThe OVZA-20-1 Relay from ASEA BROWN BOVERI (the lineage that became ABB) is a historical industrial relay documented with a 500 V rating and the UNMP designation in product listings. This exact model appears in secondary marketplaces and catalogs under the OVZA-20-1 name, reflecting its place in ASEA BROWN BOVERI’s control-relay lineup. Typical use for relays of this type is to serve as a compact control and protection device within electrical panels and switchgear, providing switching and signaling functions in legacy automation equipment. The pairing of the OVZA-20-1 designation with a 500 V rating is how buyers identify compatibility with older installations that require this specific ABB\/ASEA BROWN BOVERI relay family. As a product of the ABB\/ASEA BROWN BOVERI heritage, the OVZA-20-1 embodies the era’s approach to robust, discrete-control relays designed for industrial environments, where reliability in panel-based control circuits was essential. If you’re restoring or spares-curating legacy equipment, matching the OVZA-20-1 model and the listed voltage ensures you’re selecting the intended device from the historical OVZA family. \u003c\/p\u003e\u003c\/div\u003e","brand":"ASEA","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51660254708014,"sku":null,"price":406.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_a827247f-d94c-4239-80c3-96c90d0589f4.jpg?v=1769535200","url":"https:\/\/plgautomation.com\/products\/abb-ovza-20-1-relay","provider":"PLG Automation ","version":"1.0","type":"link"}
