The Sonel MZC-306R is a high-performance loop impedance meter designed for UK rail electrification engineers and commercial electricians who need reliable PSCC/Ik testing on 400 V and 650 V systems. Fully PADS-approved by Network Rail, it delivers fast, accurate fault loop impedance, resistance and reactance measurements on signalling power feeders and a wide range of LV installations.
How does the MZC-306R support everyday rail and electrical testing?
Engineers working on Network Rail’s 650 V systems benefit from the MZC-306R’s extended voltage range up to 750 V AC, allowing safe and precise Ik/PSCC measurements on electrification circuits. Its ability to differentiate phase and phase-to-phase voltage automatically, plus onboard memory for storing results, makes it ideal for rail maintenance teams, commercial electricians and PV technicians working across diverse low-voltage networks.
