Testador de RCD digital UNI-T UT582+ com teste de rampa e função Auto-RCD

Measure residual current device trip times and trip currents with precision across six test current settings from 10mA to 650mA. The UNI-T UT582+ supports x0.5, x1, and x5 multipliers, enabling comprehensive verification of AC and selective RCDs. Its ramp test automatically determines the actual tripping current from 0.4In to 1.1In, while the auto RCD test streamlines sequential testing without manual resetting.

Overview

Built for electricians and maintenance professionals, the UT582+ digital RCD tester verifies the safety and compliance of residual current devices in residential, commercial, and industrial installations. It measures trip time from 0ms to 2000ms at x0.5 and x1, and up to 500ms at x5, with selectable phase angles of 0° and 180° to test both positive and negative half-cycles. The large backlit LCD clearly displays results, and the auto power-off function conserves battery life after 15 minutes of inactivity.
