Differential relay for industrial protection,with separate sensing transformer. Intended to ensure the protection of people and electrical installations against indirect contacts, both in single-phase and three-phase systems. The differential relay must be associated with a toroidal sensing transformer of the TDC series.

Adjustable sensitivity between 0.03 and 0.3A and shooting time between 0.03 and 10s. DIN rail mounting and 230Vac supply voltage. 2 independent switched NA/NC output contacts, main channel and pre-alarm channel. The main channel is used to trigger the external trigger element, contactor or MCB circuit breaker plus firing coil.

For the adjustment to sensitivity 0.03A the delay time is canceled (according to IEC60947-2 annex M).

Immunized Class A differential protection, with high frequency current filtering, 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.

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