Powered from the 50\/60 Hz system with no external supply, it accepts current from a current transformer with a five-amp secondary and is offered in five- or one-amp CT configurations, with the BE1-50\/51M-209 variant using the horizontal Case Style C1 mounting. It supports single-phase, two-phase-with-neutral, three-phase, and three-phase-with-neutral input configurations and provides both 50 instantaneous and 51M time-overcurrent protections with field-selectable curves and a continuously adjustable pickup. Time-element settings range from 0.5 to 15.9 A and instantaneous settings from 1.0 to 99.0 A; an optional second independent instantaneous element is available to reduce arc-flash hazards, and the relay offers easy in-case testing, drawout construction, and retrofit compatibility with multiple mounting options.\u003c\/p\u003e\u003c\/div\u003e","brand":"BASLER","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51676722135342,"sku":null,"price":363.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_f96e7439-de4f-47d2-958d-8d90fc531ef4.jpg?v=1769552623","url":"https:\/\/plgautomation.com\/products\/basler-electric-be1-50-51m-209-overcurrent-relay","provider":"PLG Automation ","version":"1.0","type":"link"}
