ProTag PAC-3P Three Phase Appliance & Lead Tester

Only $1,349 Each EX GST Buy Now

The PAC-3P is a portable, battery powered 3 phase stand-alone test instrument for performing earth continuity and earth leakage current tests as required by AS/NZS 3760, including:

Earth continuity @ 200mA
Leakage Current Test - Mains-powered
The unit conducts a sequence test, starting with an earth continuity test and then proceeding with the leakage test. It indicates Pass/Fail and the actual measured readings on the LCD display and provides on-screen user prompts. It includes safety features such as preventing a leakage current test in event of a failed earth continuity test result. 20A and 32A extension lead test adaptor is included with an earth test pin terminal, which eliminates the need for probing of the extension lead earth.
Display LCD
Indication PASS/FAIL and measured values

ProTag RCD-3P 3 Phase RCD Testing Adaptor

Only $349 Each EX GST Buy Now

The ProTag RCD-3P is a universal three phase RCD testing adaptor that can be used with any brand of RCD tester or portable appliance tester with RCD test function.

The ProTag RCD-3P ONLY suits 5 pin three phase sockets and is available in 2 models: RCD-3P-20A for 20A sockets and RCD-3P-32A for 32A sockets. The RCD-3P units feature three inbuilt 500V ceramic fuses, i.e. one fuse per phase, ensuring operator safety.

The RCD-3P allows for fast and easy 3 phase RCD testing:
1. Insert the three phase RCD testing adaptor's plug into the three phase socket outlet
2. Turn on your RCD/PAT tester to the RCD test function
3. Plug the RCD/PAT tester's test lead cable into the L1 socket of the RCD-3P
4. Ensure the RCD is reset and switched on at this stage
5. Conduct the desired RCD tests
6. Repeat the testing procedure carried out for L1 socket with L2 and L3 sockets
7. Note the RCD should be reset after tripping before continuing the tests.
