Overcurrent Protection Circuit Dc. Stalling the motor cause short circuit. The circuit is tested and the output was observed to successfully get disconnected at different values set by the variable resistor.
When the power is connected to the circuit makes all leds on but no power in load when i press the sw1 push button motor connected to the load is working only one led is on but as soon as i release the sw1 motor stop working. And this is the board i made based on that schematic. With dc circuits the overcurrent protection is always placed in the positive side.
Whether or not it s the primary day of the electrical system or thirty or more years later it s vital that overcurrent protecting devices perform underneath overload or contact conditions as supposed.
As with any fuse selection the three elements of system voltage normal load current and available short circuit must be considered. Stalling the motor cause short circuit. A relay could be used for switching the load 12v dc motor on and off. The goal of overcurrent protection is to provide protection at the source of power for each circuit.
