Got questions, ask an expert!
The UNI-T UT586+ measures RCD trip time and operating current across selectable test currents from 10 mA to 1000 mA, with support for single-phase and three-phase systems. Its Auto Ramp testing, wiring checks and CAT III 600 V rating make it suitable for electrical installation, inspection and maintenance work.
Key Features
- Wide RCD Test Range – Provides selectable rated test currents from 10 mA to 1000 mA.
- Multiple Test Modes – Supports X½, X1, X2, X5, Auto Ramp and Manual Ramp testing.
- Trip Current and Time Testing – Auto Ramp mode measures the operating current and trip time together.
- Voltage and Wiring Checks – Measures L-PE voltage and frequency while identifying incorrect or missing connections.
- Electrical Safety – Rated CAT III 600 V and compliant with IEC 61010-031 and IEC 61557-1/6.
