Snubber Circuit Design For Relay. That said in an ac circuit a varistor or rc network happens to be the most effective. In most cases a very simple design technique can be used to determine suitable values for the snubber components r s and c s.
An rc snubber can be a highly efficient circuitry in limiting the initial voltage across the opening relay contacts while the tvs or mov may be a more efficient alternative for restricting peak surge voltages.

The snubber across the motor may not bother the motor itself but may well severely bother anyone silly enough to think that the switch being off means that the circuit is safe or dead.
There are many kinds of snubbers like rc diode and solid state snubbers but the most commonly used one is rc snubber circuit.
The first classification of snubber circuits is wheth er they absorb energy in controlling a voltage or a current. Start date may 22 2018. Proper design of the snubber can result in higher reliability higher efficiency and lower emi. Among many different kinds of snubbers the resistor capacitor rc snubber is the most popular snubber circuit.
