Hello friends, today in this video I've shown how to make a simple short-circuit protection circuit using a relay. You can use this circuit 6v to 12v battery. But for 12V battery use a 12v relay. The load current depends on the relay's specification.
Components required:-
1 x relay ( Relay voltage as per your Battery )
2 x led
1 x 1K resistor
1 x push button switch

Thank you very much for watching

The relay switches off AFTER and because the power supply has been overloaded already.Try this with a car starter battery, and it will burn your relay or the cables. Press the button while the output is shortened, it will destroy the button. Try this with an unprotected AC adapter, it will destroy the adapter. Try this with a protected AC adapter and ask yourself if you need this relay.

When output to the motor was short-circuited, it actually shorting the battery power source to 0 volts, preventing the holding relay voltage to 0 volts, great circuit for up to 12 volts, not for any other voltages, unsafe practice, thanks.

When output will be short Positive volts goes to relay coil from another side, it will be shut off because of same polarity voltage goes for relay coil. Its only for 6v - 24v DC, its not recommended for high voltages.

Is it safe to use relay as this way? Without a 1n4007 diode in relays coil terminal? In this circuit no reverse voltage is generated by the relay? Please replay me as soon as possible 🙏

i made the circuit, but when i shorted the o/p the relay didn't de-energize, infact the wires smoked & i had to disconnect the power, i think the circuit works with ps who already have s/c protection, i powered up using 3s 18650 w/o bms, also when i gave power through 12V 1A smps adapter the circuit worked as intended cause the smps was cutting the o/p & de-energizing the relay.

Dei um "não gostei" porque o circuito não considera um resistor de alta potência para dissipar o curto, ou caso seja bem calculado, pode até controlar sobrecarga. NÃO APLIQUEM ESSE CIRCUITO COMO PROTEÇÃO DE TOMADAS 110V OU 220V AC! E também não recomendo se estiver usando baterias de Lithiun.
