The INT185 current transformer is used for current measurement of machines and equipment (e.g. motors of pumps). It is connected to the KRIWAN protective relays that have a current transformer input. The evaluation takes place in the KRIWAN protection relays. The small dimensions facilitate installation in the control cabinet. The current transformer is available in different versions, e.g. with measuring range up to 100A or up to 250A and with stranded wires with ferrules or with screw terminals.

The current transformer is connected to the current transformer input of the KRIWAN protective relays. The evaluation takes place in the KRIWAN protective relays. The current is measured single-phase by means of the current transformer. The phase of the motor is fed through the opening of the current transformer, and the current transformer acts as a feed-through transformer. For three-phase motors, the motor is assumed to be symmetrical. The current transformers differ in measuring range, frequency converter suitability and connection type. The differences are listed in the technical data table.
The following features distinguish the current transformer:
