UNI-T UT 582+ Digital RCD (ELCB) Tester

Precision RCD/ELCB Trip Testing: Designed to accurately test residual current devices (RCDs and ELCBs) across multiple trip current ratings (10mA, 20mA, 30mA, 100mA, 300mA, 500mA).

RCD Trip Time & Trip Current Measurement: Fast digital processing measures exact disconnect time (up to 1000ms) and ramp trip current thresholds to evaluate breaker sensitivity and safety compliance.

Selectable Phase Angle Switch (0° / 180°): Features 0° and 180^ phase selection switches to detect phase-dependent tripping behavior across positive and negative half-cycles.

Auto-Ramp & AUTO TEST Sequence: Includes an automated testing function that systematically ramps current to diagnose non-tripping or over-sensitive RCD breakers without manual adjustments.

AC Voltage & Continuity Inspection: Measures AC mains line voltage (30V - 600V) with live wiring check indicators prior to initiating RCD fault testing.

Large Backlit LCD Screen with Data Hold: High-definition digital LCD display provides clear, illuminated test readouts and holds values on-screen for accurate reporting.

Housing & Cable Hardware: High-impact, double-insulated ABS protective housing equipped with heavy-duty test lead sets and a protective zippered carrying case.

Technical Specifications:

Test Current Settings: 10mA / 20mA / 30mA / 100mA / 300mA / 500mA.

Trip Time Range: Up to 1000ms.

AC Voltage Range: 30V - 600V (50/60Hz).

Power Supply: Powered by 6 x 1.5V AA batteries.

Safety & Usage Advice: CAT III 600V Rated. Perform zero-voltage checks before testing and ensure all connected loads are disconnected prior to executing RCD trip tests to prevent equipment interruption.

Maintenance & Cleaning: Keep terminal ports and test leads dry. Wipe the protective casing clean using a soft, dry microfiber cloth.

Essential Electrical Safety Inspector for Pros: Position as a top-tier RCD/ELCB compliance tester for certified electricians, building inspectors, electrical panel builders, and safety compliance engineers.

Highlight Auto-Ramp & Phase Angle Features: Emphasize its auto-test sequence and 0° / 180° phase switching as key efficiency features for rapid, hands-free residential and industrial safety audits.

Recommended Cross-Sell Add-ons: Pair with UNI-T UT 511 Insulation Resistance Tester (100V - 1000V), Uni-T UT07 Socket Tester, Uni-T UT12D-Non Contact AC Voltage Detector, 24-1000V AC, and DL8003 12-240V AC.DC digital test pen.
