Contact reliability:

To ensure high switching reliability, we recommend a minimum load of:

- AC/DC 24 V, 100 mA with silver contacts (standard)

- AC/DC 10 V, 5 mA with gold-plated contacts (extra code "702")
Rating surge voltage:

2500 V (via the switching contacts 400 V)
Over-voltage category II
