A priority type overcurrent blocking multifunctional multitap is provided to sequentially block currents based on priorities, thereby realizing high stability when overcurrents are incoming. A sensor(10) perceives currents incoming to the inside of an outlet. A microprocessor(20) is connected to the sensor. A speaker(30) rings a warning sound when overcurrents are incoming. LEDs(Light Emitting Diodes) notify a user whether currents are flowing. If currents less than a certain level are flowing, a current control apparatus(40) controls the currents incoming to the outlet from a microprocessor. Signals for blocking the currents are transmitted to current break devices connected to each hole of the outlet.
