Relay MKU-48-S RA4.501.088 is single-stable, two-position, with a combination of making, breaking and switching contacts, powered by direct and alternating current, designed for switching electrical circuits of direct and alternating current with a frequency of 50 Hz.

1. Winding supply current – direct, variable.
2. Insulation resistance between current-carrying elements, between current-carrying elements and the case, not less than:
– in normal climatic conditions – 200 MΩ.
– in conditions of high humidity:
– between contacts, between contacts and case – 10 MΩ.
– between the windings, between the windings and the case – 5 MΩ.
– at maximum temperature (after holding the winding under operating voltage) – 20 MΩ.
3. Test alternating voltage between current-carrying elements, between current-carrying elements and the case:
– in normal climatic conditions – 1500 V.
– in conditions of high humidity – 900 V.
4. The total time the winding is under operating voltage is 100 hours.
5. Contact material – SrMgNTsr-99.
6. The resistance of the electrical contact at the stage of delivery is not more than 0.1 Ohm, during storage – no more than 1.5 Ohm.
7. The weight of the open relay is not more than 360 g, the weight of the covered relay is not more than 600 g.
