The invention discloses an integrated test system for a PTC (Positive Temperature Coefficient) resettable fuse, which comprises an alternating current input interface, an alternating current power supply, a direct current power supply, an action time test module, an inaction time test module, a voltage withstanding life test module, an industrial frequency impact resistance test module, a voltage instrument, a current instrument, a resistance instrument, a relay, a computer, a GPIB (General Purpose Interface Bus) card and an I / O (Input / Output) card, wherein the computer transmits an on-off control instruction to the relay through the I / O card; the relay is switched on or off to generate various test conditions of a PTC resettable fuse; the voltage instrument, current instrument and resistance instrument acquire voltage, current and resistance data of each test module; and the GPIB card is inserted into the computer to carry out data processing so as to obtain a test result. The system disclosed by the invention finishes the integrated test on the PTC resettable fuse, electronically records the test result and obviously improves the test efficiency.
