The 3UG4625 residual current monitoring relays are used in conjunction with the 3UL23 residual current transformers for monitoring plants in which higher residual currents are increasingly expected due to environmental conditions. Monitoring encompasses pure AC residual currents or AC residual currents with a pulsating DC fault current component (transformer typeВ A in accordance with DINВ VDEВ 0100-530/IECВ TRВ 60755).
