Electronic Fuse Circuit Diagram. A fuse is always connected in series with the device that is intended to be protected so that when the fuse blows the flow of current to the device immediately stops. Initially the load current flows through scr and resistor r1 the value of r1 is so selected that the.
To solve this problem we build this electronic fuse limiter circuit so instead of plain fuses. The circuit may be difficult. The circuit uses only one transistor one scr one push button switch and two resistors.
Most power supply protection circuits use a low value high wattage resistor connected in series with the load for current sensing.
An electronic fuse is a safety device that is designed around a conductive strip it is intended to break or melt in the event of any excessive current flowing through the device. Here the circuit is constructed to monitor the operating current of a motor load which operates on 12v. Thus wasting time. The current flowing through the thyristor t1 will sink below the holding level when the current is rerouted through the transistor t2 2n3055.
