Abstract

See full text

A load protection and control apparatus (1) for protecting and controlling an electrical load connected to the load protection and control apparatus (1) comprising an overcurrent protection circuit (1A) having a power switch (5) through which the electrical load receives an electrical load current (IL) and having a sensor component (4) connected in series with the power switch (5) and adapted to generate directly a voltage drop (ΔU4) corresponding to the current rise speed of the electrical load current (IL) flowing from an input terminal (2) of the load protection and control apparatus (1) via the sensor component (4) and the power switch (5) to the output terminal (3) and having a driver circuit (6) adapted to detect an occurring overcurrent depending on the voltage drop (ΔU4) generated by the sensor component (4) and/or depending on a voltage drop (ΔU5) along the power switch (5) and adapted to switch off said power switch (5) upon detection of an overcurrent within a switch-off period of less than one millisecond; and/or comprising a power supply control circuit (10) having a sensor component (9) adapted to measure at the input terminal (2) a supply voltage (U) notified to a control unit (8) of the load protection and control apparatus (1) adapted to control an electrical power supplied to the electrical load, wherein each input terminal (2) is configured to establish an electrical connection with a busbar (14) of a busbar system or with a current carrying wire.
