Megger MCC1010 and MVC1010 – 1000A AC Current Clamp

• Measures AC current up to 1000 A with 1000:1 step-down ratio and 1 mA/1 A sensitivity.
• Large jaws accommodate cables up to 52 mm diameter.
• Excellent accuracy (0.3% at full range) and low phase shift (0.7° at full range) for power and energy applications.
• Overvoltage-protected output terminals with 1 Ω burden requirement.
• CAT IV 600 V safety rating per IEC 61010.
• Dual use: MCC1010 induces current; MVC1010 measures voltage drop for non-contact resistance testing.

The Megger MCC1010 and MVC1010 current clamps provide a reliable, high-performance solution for AC current measurement and specialised low-resistance applications. With their high-permeability FeNi cores delivering superior linearity and minimal phase error, they excel in power quality analysis, motor testing, and clamp-enabled earth resistance methods such as ART and stakeless testing. The large jaw opening handles thick cables comfortably, while the robust voltage-limiting protection keeps output safe under all conditions. When used together—MCC1010 to inject current and MVC1010 to sense voltage drop—they enable accurate non-contact resistance measurements without breaking the circuit, making them invaluable for field technicians working on earthing systems, conductors, or joints in demanding CAT IV environments.
