BENNING MA 4 Current Clamp Adapter 100 A AC/DC, 10 mV/A, CAT III 300V 044162

The BENNING MA 4 is a current clamp adapter engineered for precise AC/DC current measurement up to 100 A without breaking the circuit. Its 12 mm jaw opening and 10 mV/A output make it an indispensable tool for electricians and technicians working in confined spaces.

Advantages

Non-invasive measurement, high accuracy, and a compact design. The adapter converts current into a safe millivolt signal, compatible with any multimeter with >1 MΩ input impedance. Manual zero adjustment ensures precise DC readings.

Suitable for

• Electrical installation testing and troubleshooting
• Industrial maintenance and motor current monitoring
• Automotive diagnostics (with appropriate safety precautions)
• Laboratory and field service applications

Key specifications

• AC/DC current range: 0.1 A to 100 A
• Output signal: 10 mV/A
• Basic accuracy: ±1.5% rdg + 2 digits (DC), ±2.0% rdg + 2 digits (AC 45–65 Hz)
• Frequency response: DC to 20 kHz (-3 dB)
• Jaw opening: 12 mm
• Safety: CAT III 300 V, CAT II 600 V
• Connection: 4 mm safety plugs, 1.2 m cable
• Power: 9 V battery (PP3/6LR61), approx. 100 hours life

Recommendations

For reliable current measurements in tight panels or crowded wiring, pair the MA 4 with a high-impedance digital multimeter. Always verify zero before DC measurements and replace the battery when the low-battery indicator appears.
