Fluke 2277225 Ac Current Clamp 400 Amps

Product Description

The FLUKE 2277225 is an AC current clamp adapter designed for use with digital multimeters, allowing electricians and technicians to measure alternating current without breaking or interrupting a live circuit. The clamp jaw closes around a single conductor and outputs a proportional signal that the connected multimeter reads as current. This makes it a practical tool for field diagnostics, panel troubleshooting, and load verification on residential and commercial electrical systems. Its design meets industry-standard safety ratings, keeping the technician isolated from live conductors during measurement.

This current clamp adapter is commonly used by licensed electricians, HVAC technicians, and industrial maintenance professionals who need non-intrusive current readings on energized circuits. Typical applications include verifying motor draw, checking branch circuit loading, confirming compressor amperage, and diagnosing electrical faults without de-energizing the system. It connects to the input jacks of a compatible digital multimeter to extend that meter's current measurement capability.

Key Features

• Measures AC current without opening or interrupting the circuit under test
• Clamp-style jaw closes around a single conductor for accurate inductive measurement
• Outputs a signal compatible with standard digital multimeter input jacks
• Industry-standard safety ratings for use on live electrical systems
• Suitable for residential and commercial electrical, HVAC load verification, and motor diagnostics

Compatibility

Designed as an accessory clamp adapter for use with compatible FLUKE digital multimeters that accept a current clamp input signal.

Installation Notes

This accessory is installed and used by qualified electricians or technicians familiar with electrical safety practices. Before connecting the clamp leads to the multimeter, confirm the meter is set to the correct measurement mode and input jack. Always clamp around a single conductor only — clamping around multiple conductors simultaneously will produce an inaccurate or null reading. Follow all applicable NEC safety guidelines and use appropriate personal protective equipment when working near energized conductors.
