Earth Fault Relays & Torrioids
Here you will find an introduction to our earth fault relay's, along with descreiptions and part numbers. Information on our integral torroids follows below.
Introduction
Our earth fault relay's ensure the protection of electrical installations. Supplementary protection against direct connections can be achieved with our 30mA version's. This range of electronic earth fault relays provides monitoring of earth fault currents. When the fault current rises above the selected level, the output contacts of theproduct operate.
Depending on the relay selected, it can have either fixed or adjustable sensitivity, a time delay is also available for
selectivity purposes. The relays are linked with detection torroids, 14 separate types are available, circular and
rectangular.
