The invention relates to a residual current protector, comprising a zero-sequence transformer, a detection coil, a signal regulation circuit, a logical processing module, a releaser, a test coil and a direct current power supply device. The residual current protector adopts a measurement switch, a simulation current generator, a trip sensitivity setting device and a parameter regulation resistor RS to form a device with optimized performances. A three-jointed RC phase-shifted oscillation circuit is used in the simulation current generator; and the measurement switch controls on-off of a low voltage direct current power supply provided to the RC phase-shifted oscillation circuit, and when the low voltage direct current power supply is switched on, the RC phase-shifted oscillation circuit outputs an excited signal with an alternative current sine wave form to the test coil. The power supply mode of the simulation current generator powered by the low voltage direct current power supply is optimized, and the trip sensitivity of the residual current protector under the test condition is not relevant to the set parameters of the trip sensitivity setting device and is higher than the trip sensitivity of the residual current protector under the normal condition, thereby greatly simplifying the structure of the circuit, reducing the volume of the product and improving the safe reliability and durability of the product.
