It uses the PR212\/P-LSIG microprocessor-based release, delivering long-time, short-time, instantaneous, and ground-fault protection to coordinate trips with upstream devices and protect feeders, motors, and transformers. As part of the SACE Isomax S4 family, the unit supports plug-in\/front-mount configurations and is intended for installation in panels, switchboards, and motor control centers in harsh industrial environments. The 690 V rating makes it suitable for medium-voltage distribution networks, while the 250 A current rating covers typical feeder and motor-circuit protection in manufacturing plants and process industries. Because PR212\/P-LSIG is a microprocessor-based release, the unit provides precise tripping decisions, improved diagnostics, and compatibility with ABB's Isomax protection philosophy for selective, reliable switching. Common applications include motor feeders, transformer protection, and distribution boards where reliable interruption of faults at up to 690 V is required.\u003c\/p\u003e\u003c\/div\u003e","brand":"ABB","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51656732737838,"sku":null,"price":218.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_fdefd0ac-0d26-4d72-ae28-108da28fd9ef.jpg?v=1769463023","url":"https:\/\/plgautomation.com\/products\/abb-pr212-250a-690v-circuit-breaker","provider":"PLG Automation ","version":"1.0","type":"link"}
