Relays RP7 RS4.521.000 sheathed, polarized, with one switching element, designed for switching DC electrical circuits.

1. The supply current of the windings is constant (pulse).
2. Insulation resistance between current-carrying elements, between current-carrying elements and the case, not less than:
– in normal climatic conditions – 100 MΩ.
– in conditions of high humidity – 5 MΩ.
– at maximum temperature (windings under current) – 100 MΩ.
3. Test alternating voltage:
– in normal climatic conditions:
– between current-carrying elements and the case – 350 V.
– between contacts – 250 V.
– between the windings – 110 V.
– in conditions of high humidity:
– between current-carrying elements and the case – 210 V.
– between contacts – 150 V.
– between the windings – 70 V.
4. The resistance of the electrical contact is not more than 1.5 ohms.
5. Relay weight no more than 220 g.
