MI 3122 SMARTEC Z Line-Loop / RCD EN

Product catalog summary

Overview: The MI 3122 Z Line-Loop/RCD tester is designed for verification, maintenance, and periodic testing of electrical installations. It evaluates protective measures in low voltage (LV) installations and is suitable for troubleshooting live installations, including CAT IV installations.

Standards: The instrument complies with IEC/EN 60364, VDE 100, BS 7671 17th edition, and CEI 64.8. It also adheres to IEC/EN 61557 Parts 1,3,6,7,10, IEC/EN 61010-1, and IEC/EN 61326 standards.

Main Features:

Supports live tests on LV-electrical circuits, including loop and line impedance tests.
Built-in fuse characteristics for quick evaluation.
RCD tests including trip out time, contact voltage, ramp test, and Autotest.
Testing on 1- and 3-phase systems with phase sequence test.
High accuracy non-tripping loop test for RCD protected circuits.
Pre-programmed limits with PASS/FAIL evaluation and visual indicators.
Magnetic holder for hands-free operation and built-in battery charger.
Two-level memory structure for saving test results and parameters.
Compatible with EuroLink PRO and EuroLink PRO Plus PC software packages.

Technical Specifications:

RCD Testing: Nominal residual current ranges from 10 mA to 1000 mA with sine-wave and pulsed test current shapes.
