Selec 900ELR-2-230V-CE, earth leakage relay


900ELR-2-230V-CE is a Digital Earth Leakage Relay designed for monitoring leakage currents in both 3-phase and 1-phase systems. It supports various electrical connections and features a clear 3-digit LCD display with backlight. The relay offers adjustable trip settings from 30mA to 30A and includes time delay features for power-on, trip, and recovery. It maintains high accuracy in current measurements and time settings, with ±5% tolerance and an additional 100ms allowance.

Equipped with two changeover output contacts, the relay supports external system integration, with normally closed (NC) and normally open (NO) ratings of 3A and 5A respectively, both at 250V AC. It operates with supply voltages of 230V AC and 110V AC, and its compact size of 35mm and DIN Rail Mounting ensure easy installation. Holding CE certification, it adheres to stringent safety standards, making it a reliable choice for comprehensive earth leakage current monitoring
