Plug-in relays, whose output contacts change instantaneously from non-working position to working position when its coil is fed, with these contacts going back to the initial non-working position when the coil is not fed any more.
There are relays with 2, 4, 8 and 16 inverted contacts (models RD-2, RF-4, RJ-8, RI-16) as standard relays. This range is complemented with:
- Relays with free moving diode, in parallel with the coil, models RD-2DI, RF-4DI, RJ-8DI;
- Trip relays, models RD-2R, RF-4R, RJ-8R;
- Relays with seismic characteristics, models RD-2SY, RF-4SY, RJ-8SY;
- Relays with seismic characteristics, and diode in parallel with the coil, models RD-2SYDI, RF-4SYDI, RJ-8SYDI-
All the 2, 4 and 8 contact relays can be supplied with LED or mechanical indicators, trip flag, with a high breaking capacity and push-to-test button for cable checking.
