Abstract

A method and electronic safety device including a switching element for disconnecting and/or limiting the current consumption of an electrical load, wherein control commands for the switching element are received through a remote control interface, and wherein the switching element is only switched on or off when the thermal load on the switching element is within a permissible range such that there is no longer any need to provide a dedicated relay in electrical systems for remote-controlled switching operations.
