A power semiconductor arrangement has a switching facility, a housing, having a load connection facility for connecting in an electrically conductive manner to an external supply line and having a first plug-in connecting facility for plug-in connecting to an external second plug-in connecting facility. The housing has a first opening through which a connecting facility for connecting the load connection facility and the associated external supply line is accessible. A cover facility for covering the first opening is on the housing so as to be mechanically movable from a first end position into a second end position and has a first locking facility which cooperates with the external second plug-in connecting facility, whereby the first opening is closed with the cover facility as long as it is in its first end position, as long as the external second plug-in connecting facility is inserted into the first plug-in connecting facility.

Power semiconductor arrangement having a cover facility and method for releasing it

A control device for a power semiconductor switch, has a first, second and third electrical control device terminal, and a control device that according to a control signal generates an actuation voltage on the third control device terminal and actuates the power semiconductor switch. An overcurrent detection circuit determines a first voltage corresponding to a primary power semiconductor switch voltage present between the first and second control device terminals and, if the first voltage, further to commence the generation of an actuation voltage for a switch-on of the power semiconductor switch, and if the voltage exceeds a reference voltage, to generate an overcurrent detection signal. A blocking circuit blocks the output of the overcurrent detection signal from the overcurrent detection circuit, if a control current flowing in the third control device terminal for the actuation of the power semiconductor switch exceeds a first current value and/or is designed to block the output of the overcurrent detection signal from the overcurrent detection circuit, if the actuation voltage is smaller than a first voltage value.
