Safety and protection
Dielectric strength (control/load circuit) (AC, 1 min) | 5 kVrms |
Dielectric strength (open contact) (AC, 1 min) | 1 kVrms |
Dielectric strength (load/load circuit) (AC, 1 min) | 2.5 kVrms |

Notes
Note | To prevent damaging the gold layer, 30 VDC switching voltages and 50 mA currents must not be exceeded. Higher switching power eventually evaporates the gold layer. The resulting deposits in the housing may reduce service life. |
