An electrical device has a plug-in connection device (15), which is used to open and close an electrical circuit (24). The plug-in connection device (15) contains at least two contact/mating-contact pairs (22, 23), which have different ignition protection types. At least one of the two contact/mating-contact pairs is designed to interrupt the current running through said contact/mating-contact pair without triggering an explosion. (Ignition protection type Ex d or Ex i.) The other contact/mating-contact pair (23) opens and closes in the currentless state. Therefore, the other contact/mating-contact pair can have a second ignition protection type, such as Ex e. |
