KEW 5410 leakage switch tester Test RCD trip time:
× 1/2 range test rated non-operating current.
× 1 / × 5 range test RCD trip time. Residual current test: automatically use different currents to test the residual current value.
Remote test:
The test line can be operated with both hands after the test key is locked.
Automatic test after detecting main voltage. Voltage test: Test the rated voltage in the standby mode of each range.
Automatic detection of contact voltage:
During the RCD test, the ground voltage of the ground electrode or protective conductor is detected.
Use grounding in the test to avoid electric shock (after applying test current).
Stop testing when AC50V or higher. Backlight function: suitable for operation in dark places.
Waterproof and dustproof: The design conforms to the international safety standard IEC60529 (IP54).
