Megger Loop Impedance and RCD Combined Tester, ±2% ±1V Voltage Measurement Accuracy, Backlit Display - LTW300 Series - LTW425-EU-BS
Examine your circuit protection devices for efficiency with this loop impedance and RCD combined tester from Megger. It checks your loop systems, measuring the resistance of electrical loads and safety components like fuses and breakers to find high-resistance connections. The unit also assesses the trip time and sensitivity of your RCD to ensure it reacts quickly to leakage faults. Thanks to non-trip testing, you can monitor your live network without setting off ≥30mA RCDs, which prevents downtime. A backlit display means you won't miss a thing, even when you're working in dark spots.
