The RDT series is a range of relays with delay on pickup or on dropout, comprising 6 models with 4 changeover contacts, 10 A (nominal). These relays are made up of the RDM series and an electronic circuit. Models available with 4 delayed contacts or with 2 delayed contacts + 2 instantaneous contacts. Highly reliable electronic circuit, equipped with high-performance electronic components. Programmable function (on pickup or on dropout), switching time selectable from 0.1 s to over 16 hours, with extreme accuracy across the entire scale and high resolution. Equipped with knurled contacts providing low contact resistance thanks to multiple electrical contact points:

- Extended electrical life of the relay

- Excellent performance for high DC inductive loads as well as for very low loads, such as interface signals.

- Optional magnetic blow-out for higher interruption capacity.

The excellent electrical and mechanical performance of these relays allows them to be used in the most demanding mains, such as:

- Control and signalling functions in power stations

- High-voltage and medium voltage substations

- Rail transport or industries with continuous production processes.

High immunity to electromagnetic disturbances typical of high-voltage substations.
