earth-leakage protection relay / 2 NO/NC / panel-mount / differential
Contrel ELR-2M has ELR connected with mechanical signalisation. This allows it to maintain details of a tripped relay, even without auxiliary supply. Thus the risky inconvenience of having the door open on an energized panel is eliminated.
It offers auxiliary voltage supply of 110-230-400 Vac ± 20% or 110 Vdc or 24-48 Vac/dc. The range of trip current setting IΔN is 0,025 to 0,25A K=0,1; 0,25 to 2,5A K=1; 2,5 to 25A K=10; and 25 to 250A. The range of tripping time setting between 0,02 to 0,5 seconds K=1, and between -0,2 to 5 seconds K=10. The alarm current setting range is 70% IΔN. The output changeover contacts are Nr.2 5A 250V. Its working temperature range is between -10 to 60°C.
