Abstract An electronic thermorelay is composed of current sampling circuit, voltage isolating circuit, active semi-wave rectifier, three-phase peak detector, current regulator, inverse-time relay circuit, voltage comparator and cut-off circuit. Its inverse-time relay circuit is a resistor-capacitor relay circuit formed by serially connected resistors and capacitors. It can be widely used for electric motors or in over-current protecting fields.
