The Earth Leakage Relay ELR-B type is suitable for application where very reduced dimensions are necessary. The relay allows to easily select the tripping current value (0.3A or 0.5A) and tripping delay time (0.02s or 0.5s). These adjustments allow to perform a tripping selectivity of either current or delay when more relays are located along the same line.
