Electronic device for load control with overcurrent protection
The patent US12046892B2 describes an electronic installation device designed for controlling electrical loads within an electric circuit. This device features a circuit board arrangement that can be either single-layer or multilayer, incorporating various electrical components and conductor tracks. It includes a load circuit and a control circuit that are functionally interconnected. Notably, the device is equipped with two overcurrent protection mechanisms: a first device to guard against short-circuit currents and a second to protect against overload currents. The load circuit is structured with a series arrangement of an overcurrent protection device, a resistor element, and a circuit interruption element, which can be linked to a current source and an electrical load.
Further details reveal that the control circuit's second overcurrent protection device includes an overcurrent detection mechanism and a control device connected to the circuit interruption element. The overcurrent detection device utilizes a reversible sensor element thermally coupled to the resistor element, which is preferably a positive temperature coefficient thermistor. The resistor element can be configured as conductor tracks of varying widths and thicknesses, designed to absorb short-circuit currents while detecting overload currents. The patent also specifies that the first overcurrent protection device is irreversible and that the melting integral of the protected components exceeds that of the fuse in the first overcurrent protection device. Additionally, the arrangement of the components allows for effective thermal management and operational safety, ensuring that the device can respond appropriately to different current conditions.
