UNI-T UT586+ Residual Current Device Tester

We provide a 3-year warranty on this product. UT586+ digital residual current device tester.
The UT586+ is a device designed to verify the functionality of single-phase and three-phase equipment against electrical leakage. It is capable of measuring fault trip times and the currents that trigger the equipment. Thanks to its CAT III 600V safety rating, it is widely used in the residential, educational, energy, manufacturing, metallurgical and chemical sectors.
The UNI-T UT586+ represents a new generation of testers for diagnosing residual current devices (RCDs). It enables detailed testing of the tripping time and tripping current of RCDs up to 1000 mA. Thanks to integrated functions such as the automatic ramp (AUTO RAMP), testing at phase angles of 0° and 180°, and a built-in socket connection check, it is an ideal tool for electricians, inspection technicians and industrial maintenance staff.

- Operating voltage: 50/60 Hz 100 V to 440 V (Note: If > 450 V, an alarm is triggered and the residual current device test is halted) -15 % to +10 %

- Voltage test: Voltage range: 30–480 V (resolution: 1 V) 45–65 Hz ±3% of reading ±3 digits
L-PE: yes, display L-PE input voltage, range: 30V–480V; no input and low voltage: ‘0 V’; if less than 30 V: <30 V; if greater than 4800 V: >480 V
Frequency: yes, display L-PE input frequency; if displayed as ‘volts’, press the ‘VOLTAGE/FREQUENCY’ button to switch between ‘voltage/frequency’

- connection check: if no connection is made, the power supply is abnormal or no current is flowing, ‘L-PE’ will appear and flash on the LCD display
- Phase angle selection: you can start the test from the positive (0°) or negative (180°) half-cycle. Press the ‘0°/180°’ button to switch the phase
- Lockout test: with the power disconnected, press and hold the ‘0°/180°’ button to activate the lockout test function. Simply connect the test leads correctly to the test points and the test will start automatically
- Automatic inrush/rising current test: you can test the current and the trip time simultaneously - RCD test limit exceeded alert: when the trip time exceeds the maximum test duration and the device trips
- Overheating detection: the device automatically deactivates RCD testing - Backlight: can be switched on/off - Low battery indicator - Automatic switch-off: approx. 5 minutes
