Special earth leakage breaking protector for electric water heater

The utility model relates to a special electrical leakage circuit breaking protector for an electric water heater, which comprises zero sequence current transformers, a zero sequence current signal amplifying circuit, and a tripping relay. The utility model is characterized in that the tripping relay is a three-pole linking relay, and the contacts of three poles are respectively connected in series with an earthing wire of an electric water heater, and the incoming wires of the zero line and the live wire of a power source; at least one zero sequence current transformer is sheathed on a water inlet pipe or a water outlet pipe of the electric water heater; the zero line and the live wire simultaneously penetrate through the zero sequence current transformer; the working power sources of the tripping relay and the zero sequence signal amplifying circuit are connected to the zero line and the live wire on the outer side of the contact of the tripping relay. The utility model can provide full electrical leakage circuit broking protection, aiming at ubiquitous electrical leakage phenomena caused by incorrect connection for lines by people and self electrical leakage of electric appliances.
