Product Details

The Kewtech KT63 Plus Multifunction Tester can conduct PFC and PSC measurements without the user needing to alter the test probes. Its continuous live monitoring also prevents blown fuses and PCBs, moreover, the Kewtech KT63 Plus Multifunction Tester includes anti-trip technology enabling it to conduct full no-trip loop testing (with a low likelihood of RCD uplift and noise interference) on all electronic and electromechanical RCD types above 30mA. The Kewtech KT63 Plus Multifunction Tester is able to conduct RCD tests on RCDs rated 10, 30, 100, 300, 500, and 1000mA.
