UNI-T Digital RCD Tester 10–500mA with Auto Ramp | UT582+
Couldn't load pickup availability
The UNI-T UT582+ is a digital RCD (ELCB) tester for checking the trip time and trip current of residual current devices on single-phase circuits. It tests RCDs rated from 10mA to 500mA using ×½, ×1, ×5 and AUTO RAMP modes, with 0° and 180° phase selection. It also measures supply voltage from 30V to 600V, making it a practical tool for electricians and safety inspectors.
