Current Clamp Adapter Benning CC 3 — 0.2…300 A AC / 0.2…300 A DC

Benning CC 3 — 0.2…300 A AC / 0.2…300 A DC is a current clamp adapter designed to measure alternating and direct currents without breaking the circuit. The clamp converts conductor current into a measurable signal for compatible meters and testers, enabling non-intrusive current measurements from 0.2 A up to 300 A. The accessory is intended for use by electricians and technicians during troubleshooting, maintenance and installation checks where safe contactless measurement is required.

Advantages

The adapter provides a broad measurement range for both AC and DC currents in a single compact clamp, allowing rapid switching between measurement tasks. Its contactless operation reduces risk during live measurements and simplifies wiring diagnostics. The mechanical design supports easy attachment to single conductors and ensures stable readings with minimal influence on the measured circuit. The adapter is compatible with a variety of meters and testers that accept clamp-converted signals.

Suitable for

• Field and workshop current measurement on single conductors
• Troubleshooting electrical installations and equipment
• Preventive maintenance and load checks
• Verification of DC and AC circuits in automotive and industrial applications

Key specifications

• Measuring range: 0.2…300 A for AC and 0.2…300 A for DC
• Measurement method: non-intrusive clamp conversion of conductor current to test instrument input
• Compatibility: designed for use with meters and testers that accept clamp adapter input
• Construction: compact clamp housing for single-conductor application
• Safety: intended to allow live measurements without breaking the circuit (observe instrument safety guidelines)

How to use

Open the clamp and place it around a single conductor to be measured, ensuring the conductor is centered in the jaw for best accuracy. Connect the adapter to a compatible meter or tester following the instrument manufacturer’s input connection method. Select the appropriate measurement function on the meter (AC or DC) and range if required, then read the current value displayed on the meter. Remove the clamp after measurement and store it according to the meter and accessory handling instructions.

Usage recommendations

For accurate results, position the conductor centrally in the clamp jaw and avoid clamping around multiple conductors simultaneously. Follow the safety and input specifications of the meter used with the adapter, and do not exceed the stated measurement range. Use the clamp for routine diagnostics and maintenance, and verify meter calibration periodically to maintain measurement reliability.
