Product Description
The split current transformers ND5014 are suitable for differential current measurement in conjunction with a DOLD differential current monitor Il 5882, SL 5882 and IP 5882 for AC and pulsating DC current. Opening the CT makes it easy to install them to the current leading conductors. They are especially suitable for retrofit, as the wires do not need to be disconnected.
The split current transformers are available in 3 sizes with through hole diameters of 49, 79 and 119 mm.
For differential current measurement all current conducting wires run through the CT with exception of the PE wire.
Normally we have rather low currents that are monitored between 10 mA and 30 A.
Connection Terminals
| Terminal designation | Signal designation |
| i, i, k, k | Connecting the current transformer to the Residual Current Monitor IL 5882, SL 5882 or IP 5882 (i and k are double present) |
Application
Measuring current transformers for monitoring differential currents in combination with DOLD Residual Current Monitors IL 5882, SL 5882 and IP 5882.
Note
The split current transformer is only designed for operation together with the residual current monitors IL 5882 and SL 5882 from E. Dold & Söhne GmbH & Co. KG.

Mounting instructions for srew fixing
To high forces applied during installation can damage the transformer on the mounting foots.
The mounting foots are only designed to fix the transformer. Forces that are applied to the CT by the conductors can only be supported within limitations.
When installing the CT, the conductors should be lead free through the transformer and should later stay in that position.
Wiring Information
The hinged cover protects the push-in terminal block and avoids unintended disconnection of the wiring- The push-in terminal block provides easy mounting
- Stripping length: 10 mm
Connecting capacity: 0.2 …. 2.5 mm 2
