earth-leakage protection relay / 1 NO/NC / differential / panel-mount
24 V, 48 V, 110 V, 240 V, 415 V
ELR-2 is a dual-output changeover contact, one could be utilized for detachment and the other for a caution capacity at 70% of the set current (the determination of the working sort of the second contact is, no doubt made by method for a dipswitch).
With a 110-230-400-V AC, ± 20%, or a 110-V DC or 24-48-V AC/DC helper voltage supply, a tripping time setting of 0.02-0.5 sec. K=1 - 0.2-5 sec. K=10 and tripping current setting reach IΔN: 0.025-0.25-A K=0,1 - 0.25-2.5A K=1-2.5-25 A K=10 25-250 A, is showcased.
This component is designed and manufactured with a wide range of other features.
