Description

The toroids for earth leakage relays are used to measure both AC and DC leakage currents.

Thanks to its advanced technology and the quality of the materials components used, the differential toroid can be used to detecte of earth fault current without interruption and at True Root Mean Square (TRMS) value.

This toroid allows you to set the sensitivity of the earth leakage relay from 30 mA to 300 mA to guarantee the safety of people and property, and also meets the most demanding quality standards.

The type B toroid is suitable for industrial environments (variable speed drives, inverters, rectifiers) as well as electric vehicle charging stations (EVCS).
