Low Voltage Zero-sequence Detectors ITF100
Relays for detecting zero-sequence / earth fault currents on networks with low voltages.
ITF114: AC sensitive overcurrent relay with a fixed time delay of 0.4 or 1.0s
ITF115: DC sensitive overcurrent relay with a fixed time delay of 0.4 or 1.0s
The ITF113 (similar to ITF114 but with a built-in warning lamp) is no longer available. This series of relays is entering obsolescence.
A full brochure is available on the homepage for Static relays.
