Abstract
The disclosure relates to a relay having a relay contact, having an electrical connection terminal at which an electrical variable can be tapped off, a control connection for receiving a control signal for opening the relay contact, and a controller. The controller is configured to respond to the reception of the control signal by sensing a change of amplitude of the electrical variable and to open the electrical relay contact with a time delay when a rising amplitude of the electrical variable is sensed, in order to reduce an electrical loading on the relay contact. The controller is further configured to respond to the reception of the control signal by opening in a first disconnection process, to sense the amplitude of the electrical variable, to close the relay contact when the rising amplitude is sensed and to open it again, with a time delay, in a second disconnection process.
