HIOKI CM4375-50 AC/DC Clamp Meter 600 A | True RMS

The HIOKI CM4375-50 AC/DC clamp meter is a high-capacity True RMS instrument designed for measurement on large conductors, busbars, and high-current industrial circuits. The 55 mm jaw accommodates cables and busbars that would not fit standard 40 mm clamps, while AC and DC current ranges to 600 A cover the full scope of LV industrial power systems.

DC current measurement makes the CM4375-50 suitable for solar PV, battery storage, and DC distribution applications alongside conventional AC electrical work. Inrush current capture records transient start-up peaks for motor protection analysis and variable speed drive commissioning. The optional HIOKI Z3210 Wireless Adapter adds Bluetooth® connectivity for wireless data transfer and reporting via GENNECT Cross.
