Clamp Current Sensor Unit UT-CS06A — Flex Clamp, 400 A, 50–400 Hz, CAT II 600V/CAT? 300V

Unit UT-CS06A is a flex clamp current sensor designed for non-invasive measurement of alternating current up to 400 A. The flexible clamp allows access around conductors in confined spaces and supports frequency measurements in the range of 50–400 Hz. Safety markings on the product indicate CAT II 600V and CAT? 300V ratings. The sensor connects to compatible meters or data acquisition systems that accept clamp-type current inputs and is intended for troubleshooting, power monitoring and field testing applications.

Advantages

The flex clamp design provides adaptable placement around single conductors and busbars without disconnecting circuits, enabling quick on-site measurements. Support for a wide frequency range (50–400 Hz) makes the sensor suitable for a variety of AC systems. The unit’s rated current capacity of 400 A covers common mains and industrial loads, and the CAT II 600V / CAT? 300V safety markings indicate its intended insulation and overvoltage category for typical measurement environments.

Suitable for

• Troubleshooting electrical circuits and locating overloads
• Power consumption and load monitoring on distribution circuits
• Field testing and temporary measurements in installations with limited access
• Measurements on motors, generators and transformers within the specified current and frequency ranges

Key specifications

• Clamp type: flexible (flex clamp)
• Nominal current range: up to 400 A
• Frequency range: 50–400 Hz
• Safety ratings: CAT II 600V and CAT? 300V (as marked on product)

How to use

Position the flex clamp around the single conductor whose current you need to measure, ensuring the conductor is centered within the clamp loop. Connect the sensor’s output lead to a compatible meter or data logger designed for clamp current inputs and observe the instrument’s input mode and scaling. Verify that the measured frequency and current remain within the specified ranges (50–400 Hz and up to 400 A). Follow the meter manufacturer’s instructions for selecting AC current measurement mode and any required zeroing or calibration steps before recording readings.

Usage recommendations

Inspect the clamp sensor for damage before use and ensure that the working environment matches the product’s safety markings. Avoid placing the flex clamp around multiple conductors simultaneously, as this will produce incorrect readings. Use appropriate personal protective equipment and follow local safety procedures when measuring live conductors.
