摘要：
An electric switch includes a thermal tripping unit which, when a thermal budget acting on it is exceeded, trips and switches off the electric switch. In an embodiment, the tripping unit includes an adjustment module which, as a function of an accessory connected to the electric switch, uses an actuating element to set a tripping element of the thermal tripping unit such that the heat effect of the accessory is compensated for in the event of tripping.
