Accessory type: Adapter
Suitable for use with: SECUTEST S II, SECUTEST S III

Safety tester AT3-IIIE. Testing of single-phase and three-phase loads as well as extension cables in conjunction with the external testing devices SECUTEST S-II and S-III. Additional protection during the testing of defective devices under test (DUTs) through integrated residual current monitoring with shutdown. Function test of the automatic shutdown via a self-test button. Prevention of short circuits and thus the triggering of main fuses through a pre-testing stage. Automatic adjustment to the set program of the SECUTEST-Sxx testing device with transmission of the measured values. Testing in conjunction with SECUTEST SII and SIII of protective conductor resistances, insulation resistances, equivalent leakage currents, breakdown strength, fault currents, and touch currents.
