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 TD series toroidal sensing transformer.

Adjustable sensitivity between 0.03 and 0.3A and shooting time between 0.02 and 1s. DIN rail mounting and 230Vac supply voltage. Switched NA/NC output contact to trigger an external trigger element.

Class A differential protection immunized, 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.
