Basler Electric BE3-51-1E1A1 Overcurrent Relay is a single‑phase protective relay in Basler’s BE3‑51 family, designed to provide overcurrent protection for low‑voltage circuits. It operates from a 120 VAC input at 50/60 Hz and uses an energize‑to‑trip scheme to actuate the protected circuit when the current exceeds the preset pickup. Basler lists this model as discontinued by the manufacturer.
