It supports flexible input configurations—single-phase, two-phase with neutral, three-phase, and three-phase with neutral—and offers 16 field-selectable current-time curves to tailor protection to the application. Variants BE1-51\/27C (single-phase time overcurrent with voltage control) and BE1-51\/27R (three-phase time overcurrent with voltage restraint) add voltage-sensing options that improve selectivity without requiring external equipment. The BE1-51 family emphasizes accurate, repeatable protection while minimizing CT costs through a low-sensing-burden design and reducing battery drain with a low-burden power supply; it also meets surge-withstand standards for protective relays, such as ANSI\/IEEE C37.90.1, underscoring its robustness in demanding substations and industrial environments.\u003c\/p\u003e\u003c\/div\u003e","brand":"Basler","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51676714991918,"sku":null,"price":471.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_c76409aa-acfb-4c57-a295-8f8853b51b74.jpg?v=1769552601","url":"https:\/\/plgautomation.com\/products\/basler-electric-be1-51-solid-state-protective-relay","provider":"PLG Automation ","version":"1.0","type":"link"}
