The module is versatile enough to support various system earthing methods—including isolated, compensated, or directly earthed networks. Its robust hardware design is purposefully built to endure the extreme electromagnetic interference (EMI) and mechanical stresses typical of high-voltage substation environments. Furthermore, it supports integrated bay control functionality, allowing for the centralized management of circuit breakers and disconnectors within a single, secure device.\u003c\/p\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":47088468099262,"sku":"RED670 1MRK002246-BC","price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0725\/1145\/5422\/files\/screenshot_2026-05-08_11-33-39_aab38bd9-95f9-4f8e-9b40-fbc52cfde0fe.png?v=1778745909","url":"https:\/\/www.autooiltech.com\/products\/abb-red670-1mrk002246-bc-relion-line-differential-relay","provider":"AutoOilTech Limited","version":"1.0","type":"link"}
