The unit accepts a 120 V line-to-neutral input and operates at 50\/60 Hz, aligning with standard utility and on-site power supplies. As part of the BE3 undervoltage protection family, this module provides voltage monitoring and protection for single‑phase applications, backing up motor starters, transformers, and feeder configurations by de-energizing the circuit to prevent damage from sustained undervoltage conditions. The BE3-27 variant is documented in Basler Electric's BE3 series documentation and is sometimes listed by distributors as discontinued by the manufacturer, which can impact current availability and support channels. When used, it forms part of a broader protective scheme, often coordinating with other protection relays to ensure voltage thresholds are met before allowing operation. The 9319200100 designation uniquely identifies this 120 V input, 50\/60 Hz variant within Basler Electric's undervoltage protection lineup, enabling traceability for replacement parts or legacy installations.\u003c\/p\u003e\u003c\/div\u003e","brand":"Basler","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51676712173870,"sku":null,"price":116.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_0a6d7515-8800-4e35-8527-179b37a9b520.jpg?v=1769552594","url":"https:\/\/plgautomation.com\/products\/basler-electric-9319200100-be3-27-1a1n2-undervoltage-relay","provider":"PLG Automation ","version":"1.0","type":"link"}
