Rơ-le bảo vệ dòng rò đơn chức năng EL500

Littelfuse EL500 Single-Function Earth Leakage Relays are designed to measure leakage current and isolate the faulty circuit from the system. Leakage currents are sensed through a core-balance current transformer (CBCT), and when the leakage current exceeds the set level, the device will trip. The trip level and trip time settings are adjustable with front-mounted potentiometers, and additional features include LED trip and power indication, LED bar graph indication for leakage current, remote test and reset, and CT OPEN indication. The EL500 relay offers dual operation modes, supporting fail-safe and non-fail-safe wiring to fit different safety standards. Suitable applications for EL500 relays from Littelfuse include industrial panels, commercial buildings, critical systems, hazardous areas, and residential safety.
