Fluke i400 Current Clamp, AC Adapter, 400 A AC Max, Current Output

This current clamp is a Compact AC clamp designed to work with digital multimeters to measure alternating current without interrupting circuits. It delivers an output proportional to measured current for straightforward interfacing with meters and is intended for use in demanding electrical environments where high safety ratings are required.

• Measures up to 400A while allowing continuous operation at working currents
• Output of 1mA per amp makes meter readings direct and simple
• Basic accuracy of 2% Plus 0.06A supports precise diagnostics
• Usable across 5Hz–20kHz to capture a wide range of AC waveforms
• Shrouded banana jack and 1.5m cable enable safe, flexible connections
• Rated for CATIII1000V and CATIV600V for high-voltage onsite tasks

• Suitable for plant maintenance teams performing load analysis
• Ideal for electrical contractors testing distribution circuits
• Used with multimeters for fault-finding in automation systems
• Can be used for current checks on motor control panels
• Used for monitoring current on busbars up to 32mm diameter

It accepts conductors up to 32mm diameter and accommodates large busbar sizes specified as 750MCM.

It is rated to operate safely between 0°C and 50°C for typical ambient working conditions.

The device can tolerate short-term currents up to 1000A without permanent damage.

The lowest measurable current is 1A, suitable for detecting light loads and standby currents.
