Differential protection relay which allows complete differential protection by associated it with a toroidal transformer of the TD series, ensuring maximum safety and continuity of the electrical service and avoiding untimely firing. The relay can be installed on single-phase or three-phase lines.

The sensitivity is set to 30mA (0.03A) and the firing time is 0.02s: mounting is done on symmetrical perfl DIN 46277. 230Vac supply voltage. Switched NA/NC output contact to trigger an external trigger element.

Class A differential protection for the detection of alternating and alternating leakage current with continuous component, which makes it especially recommended for electrical installations with the presence of currents distorted by the presence of harmonics. Fixed detection is performed by sampling the differential intensity and calculating its true effective value (TRMS).

Note: The measurement element, the toroidal transformer is not included in the supply.
