Megger MCC1010/ MVC1010 1000 A AC Current Clamp

Description

Advanced Current Measurement with Megger MCC1010 MVC1010

The Megger MCC1010 and MVC1010 represent the pinnacle of clamp meter technology, developed for precision measurement of alternating current (AC) up to a staggering 1000 amperes. These current clamps are designed for demanding electrical environments, being compliant with CAT IV 600 V safety standards, which ensures safe operation even in high-risk industrial, utility, and commercial settings. A standout feature is their remarkable 1000:1 step-down current ratio, enabling accurate scaling of high current levels to manageable outputs for measurement instruments. Moreover, their application of high-permeability FeNi alloy in the magnetic cores provides outstanding accuracy—0.3% error at full-scale—and low phase shift (just 0.7°), making them ideal for metering scenarios requiring uncompromising precision. This reliability is a testament to Megger’s global reputation, and the MCC1010/MVC1010 models only reinforce that legacy.

Unmatched Versatility in Everyday Electrical Applications

The flexibility of the Megger MCC1010 and MVC1010 extends far beyond basic current measurement. These clamps are exceptionally well-suited for operation with power quality analyzers, oscilloscopes, and motor testers, where high accuracy and wide dynamic range are critical. They play an essential role in earth testing, being compatible with clamp-enabled earth testers and supporting advanced techniques such as the Attached Rod Technique (ART) and stakeless testing, which simplify earth resistance measurements in complex installations. The large jaw opening (up to 52 mm) allows them to accommodate a wide variety of cable sizes, from domestic installations to heavy industrial systems. Their ability to measure leakage currents makes them indispensable for preventative maintenance, helping spot energy loss or insulation faults before they escalate.

Designed for Safe Measurements in Challenging Environments

Safety remains at the core of the MCC1010 and MVC1010’s design philosophy. Rated to CAT IV 600V according to IEC 61010 standards, these clamps can safely measure current in circuits up to 600 V in the most demanding environments. The output terminals come equipped with advanced overvoltage protection via a built-in voltage limiter, ensuring the clamps can be safely handled under all conditions. The robust construction, with an IP40 rating when jaws are closed, provides solid dust resistance suitable for industrial environments. With storage and operating temperature ranges extending from the chilling cold of -40°C to the heat of +70°C, and an operating altitude up to 2000 meters, these clamps are truly engineered for fieldwork anywhere.

Precision Engineering Enhances Measurement Accuracy and Reliability

Engineered for metrology-grade performance, the MCC1010 and MVC1010 excel in delivering accurate readings across the full operating range. Showcasing a minimum sensitivity of 1 mA/A, they detect even minimal current flow, which is critical for leakage and low-current applications. Their amplitude and phase accuracy remains within tight limits: an outstanding 0.3% amplitude error for currents up to 1000 A, and phase shift capped at 0.7°, making them suitable for precise energy and power quality studies. Frequency bandwidth spans from 15 Hz to 10 kHz, accommodating both standard power frequencies and harmonic-rich environments. Load and crest factor influences remain within specification, ensuring results are accurate regardless of signal shape or connected instrumentation.

Comprehensive Clamp Usage for Modern Measurement Needs

The MCC1010 and MVC1010 are intentionally built for intuitive, reliable measurements. To ensure precision, users must only clamp around a single phase, avoiding combined phases or neutral conductors, which would yield incorrect results. For direct current reading, an ammeter reading up to 1A can be connected—thanks to the 1000:1 ratio, 1000A primary results in a manageable 1A on the ammeter. When interfacing with voltmeters or data loggers, the probe provides a clean 1 mV across 1Ω burden resistance for every 1 A of current. Compatibility with TRMS multimeters and earth testers is ensured, and the dual-clamp method (using both MCC1010 and MVC1010) enables non-contact resistance measurements. These versatile operational methods equip technicians for broad application scenarios from routine maintenance to advanced diagnostics.
