Its robust design makes it particularly suitable for use in industrial environments. The simple handling allows employees to work quickly and efficiently with the measuring adapter. You can test devices and extension cables with the following IEC 60309-1 connectors: CEE plug: 16 A, 50 Hz - 60 Hz, 230 V, L+N+PE, 6h; 16 A, 50 Hz - 60 Hz, 380 V - 415 V, 3L+N+PE, 6h; 32 A, 50 Hz - 60 Hz, 380 V - 415 V, 3L+N+PE, 6h. To do this, connect the measuring adapter to an appliance tester for testing portable appliances in accordance with DIN VDE 0701-0702 or DIN EN 62353 (VDE 0751-1) or DIN EN 60974-4 (VDE 0544-4). The appliance tester must have an earthing contact socket for connecting the measuring adapter. Depending on the type of test, a CEE 16A or 32A socket outlet may also need to be available. An adapter cable is required for CEE 16A. The measuring adapter is suitable for connection to the appliance testers: Benning ST 725, Benning ST 750 / 750A / 755 / 760, third-party devices.
