The invention relates to the field of releases, in particular to a zero-voltage delay release, which comprises a filter circuit, a starting power circuit, an electromagnet for releasing control, a switching circuit, a delay circuit for controlling delay releasing, a control circuit for controlling the turn-on/off of the switching circuit, and a regulated power circuit for supplying power to the switching circuit and the control circuit, wherein the power input end of the filter circuit is connected with a power grid, and the power output end of the filter circuit is connected with the power input end of the starting power circuit; and the power output end of the starting power circuit, the switching circuit and a coil of the electromagnet form a series loop. The zero-voltage delay release is simple in circuit, high in starting torque, reliable in closing, low in coil heat and high in charging speed; and after zero voltage, the power of the coil (the retention of an armature) is maintained to be constant, and delay time is long.
