Current transformers, coupling devices and indicators for DOLD monitoring relays

These accessories pair with specific DOLD monitoring devices. Residual current transformers ND 5015 and ND 5018 suit RN 5883, ND 5016 and ND 5019 suit IL 5882 and SL 5882, and ND 5017 suits RR 5887. The split transformer ND 5014, also for IL 5882 and SL 5882, follows IEC 61869-1 and IEC 61869-8, measures to IEC/EN 62020 (Type A, AC and DC systems) up to 30 A, and mounts on DIN rail. ND 5013 is the measuring transformer for RL 9405.

Coupling devices extend the nominal voltage range of RN 5897 devices: RL 5898 to DC 500 V / AC 400 V, RP 5898 to DC 1000 V / AC 690 V (also for RN 5893), and RR 5898 to DC 1500 V / AC 1000 V. The EH 5861 indicating instrument connects externally to an insulation monitor and shows insulation resistance to ground.
