Abstract
The circuitry can be applied in electrical engineering for the protection of users from failures caused by overvoltage in the entire voltage range up to 1000 VAC. It has multiple effect and in case of any overvoltage it discontinues the current circuit, i.e. the supply to the users. The operation of the protection circuitry is based on phase-controlled thyristor module with varistor connected to the control circuit of the thyristor, and in this way the currents across the varistor are many times smaller than their value allowances. For this reason, after the actuation of the module, the varistor remains intact and allows multiple use. The protection circuit comprises an electronic module and actuating mechanism - breaker. The electronic module of the protection circuit converts any arising overvoltage pulses above a specified value into a low voltage pulse which is fed to the actuating mechanism, discontinuing the supply to the users. The restoration of protection is made mechanicallyor automatically, depending on the type of the breaker.
