Basler Electric BE4-27 Undervoltage Relay is a 120 V AC undervoltage protection relay designed to monitor line voltage and trigger protective action when voltage dips below a preset threshold. Housed in a 12-pin (12P) package suitable for Basler socket systems, the BE4-27 operates at 50/60 Hz and is intended for installation in control panels and switchgear that require undervoltage detection. This BE4-27 model provides undervoltage protection for AC power systems, applicable to single-phase and multi-phase configurations where fast response to voltage sag is important.
