Fluke 355 | 2000A AC/DC True-RMS High-Current Clamp Meter

Large industrial conductors and high-current equipment can exceed the range and jaw capacity of standard clamp meters. The Fluke 355 AC/DC True-RMS Clamp Meter is designed for high-current applications, measuring up to 2000 A DC and 1400 A AC RMS through a large 58 mm jaw.

It also measures AC/DC voltage, resistance and frequency, while inrush-current recording helps technicians evaluate motor and equipment starting conditions. A selectable low-pass filter assists measurements in electrically noisy environments, including systems influenced by variable-speed drives. Min/Max/Average recording helps track changing loads, and the large backlit display supports field use around industrial equipment. With its wide jaw and high-current capability, the 355 is particularly suited to busbars, large feeders, and heavy electrical installations where ordinary clamp meters cannot accommodate the conductor or current level.

High-Current Clamp Meter Selection Guide

Choose the Fluke 355 when current may exceed 1000 A or conductor size requires a 58 mm jaw. For lower-current industrial work with wireless logging, the 376 FC may provide greater connectivity.

Market Relevance

The Fluke 355 is relevant to Pakistan's steel mills, cement plants, power distribution, heavy manufacturing, large motors and utility installations. Kamadi Pakistan offers the Fluke 355 for high-current industrial electrical measurement and troubleshooting.
