Prüfball ZAP 350


(VAT only for EU) plus shipping

The test ball ZAP 350 is the ideal testing tool for energy suppliers. It combines a robust voltage tester with a safe test tool for a quick start-up test when commissioning electricity meters.

The additional 350 W load is securely and waterproof integrated into our patented connection line. Thus, tests can be carried out safely in any environment.

Voltage tester:

  • precise display of the voltage 50 V – 500 V AC / DC
  • resistant to voltage – CAT IV 300 V – VDE certified
  • clear LED indicator for dangerous voltage
  • 350 W additional load for fast startup test of electricity meters and detection of interference voltages
  • full voltage indication without battery – maintenance free
  • precise, interference-free moving coil measuring unit with direct display

Continuity tester:

  • fast continuity test

Phase and phase sequence tester:

  • phase tester with red LED indicator
  • rotating field tester with LED display left / right
  • controller-monitored test with error detection to avoid false indications
  • phase and phase sequence tests can also be performed with insulating gloves

More functions:

  • safety housing made of solid rubber extremely shockproof
  • test electrodes with thread for screwing on accessories
  • easy operation
  • additional load with thermal and overvoltage protection
  • extremely stable housing, even in cold environment
  • IP 65 – waterproof
