Megger MCC1010 – High-Precision 1000 A AC Current Clamp
- Perfect for demanding electrical applications
The Megger MCC1010 is a high-accuracy, professional-grade AC current clamp engineered for advanced electrical testing up to 1000 A. Whether you‘re involved in power quality analysis, motor diagnostics, or stakeless earth resistance testing, the MCC1010 provides a powerful, precise, and safe non-contact current measurement solution trusted by engineers and technicians worldwide.
Pinpoint Accuracy Meets Practical Design
At the core of the Megger MCC1010 lies its outstanding measurement precision. With a 1000:1 step-down current ratio and a sensitivity of 1 mA per amp of primary current, this clamp delivers exceptional linearity across a broad operating range. You’ll benefit from class-leading amplitude accuracy (down to 0.3% at high current levels) and minimal phase deviation—making the MCC1010 ideal for applications where true readings are critical.
From capturing load currents to supporting power and energy audits, this tool ensures your data is not only accurate but also reliable across varying conditions.
A True Workhorse Across a Range of Applications
Versatility is where the Megger MCC1010 shines. It‘s purpose-built to work seamlessly with a wide array of instruments, including:
- Digital multimeters (with mV AC range)
- Power quality analysers
- Clamp-enabled earth testers (e.g., Megger DET series)
- Data loggers
- Oscilloscopes
- Motor and machinery testers
- Stakeless testing setups, including ART (Attached Rod Technique)
If you‘re conducting non-contact resistance testing, the MCC1010 is used to induce current, while its companion unit—the MVC1010—measures voltage drop, enabling complete contactless resistance measurements.
Megger MCC1010 Key Features:
- Excellent accuracy (0.3% error at full range)
- Offer small phase shift (0.7° at full range) perfect for metering of power, energy and power quality applications
- CAT IV 600 V current measurement to 1000 A AC
- 1 mA/1 A sensitivity with rated burden of 1 Ω
- Large jaws for cables up to 52 mm
- Overvoltage protection of the output terminals
- Suitable for leakage currents
High-permeability FeNi alloy magnetic cores deliver this exceptional performance. The output terminals are protected with a voltage limiting circuit ensuring a safe-to-touch voltage under all rated conditions.
Safety Without Compromise
Rated to CAT IV 600 V, the Megger MCC1010 meets the highest category for overvoltage protection under IEC 61010. The clamp includes a built-in voltage limiting circuit, capping output to 28 V peak to ensure outputs remain safe-to-touch in all operating conditions.
Its large, insulated jaws can accommodate conductors up to 52 mm in diameter, making it highly practical for a wide range of installations—from industrial switchboards to cramped consumer units.
Performance You Can Count On
Operating across a frequency bandwidth of 15 Hz to 10 kHz, the MCC1010 is engineered for consistent performance even in environments with complex waveforms and high crest factors (up to 2000 A peak, or 300 A RMS). With minimal sensitivity to load resistance, DC offset, or conductor placement within the jaws, you can expect consistent, reliable measurements every time.
Key specifications include:
- 1 mV output per amp of current across a 1 Ω burden resistance
- Minimal phase shift (as low as 0.7° at full scale)
- Max continuous current: 1000 A at ≤500 Hz
- IP40-rated enclosure with jaws closed
- Rugged yet lightweight design (700 g)
Effortless Integration with Your Toolkit
The Megger MCC1010 connects easily to any device with a 1 Ω burden resistance, such as a TRMS multimeter or Megger’s DET3TC, DET4TC, and DET4TCR testers. It‘s an ideal clamp for detecting leakage currents, verifying current flow, and enhancing multiphase testing with minimal setup effort.
Whether you‘re a site electrician, commissioning engineer or power quality specialist, the MCC1010 brings true plug-and-play convenience to high-current diagnostics.
