Megger LRCD220 Combined Loop/RCD Tester

The Megger LRCD220 Combined Loop/RCD Tester is built for electrical contractors who need reliable results on energised circuits. It delivers precise readings while keeping RCDs intact during loop testing. Each function is easy to operate and safe to use, making it suitable for both new installers and experienced professionals.

Advanced Testing Capability

This tester supports three-phase safe non-trip loop testing and a wide range of RCD testing options. Users can perform ½I, I, and 5I RCD tests across standard, selective, and DC types. In addition, the Megger LRCD220 extends functionality with 110 V loop testing, two-wire fast testing, and phase-to-phase and phase-to-earth checks. It prevents nuisance tripping, even with 30 mA electronic RCDs.

Designed for Practical Use

With a tough rubber armoured case and built-in protective cover, the Megger LRCD220 withstands site conditions. Its IP54 weatherproof rating ensures dependable operation in harsh environments. Test leads can remain connected whether the cover is open or closed, while clear L-N-E LEDs confirm connection status and polarity. This makes the unit practical for handheld use or bench placement.

The Megger LRCD220 offers flexibility, durability, and accuracy, all backed by a three-year warranty. It is designed to meet the everyday demands of electricians, making it a dependable companion for professional testing.
