VOLTCRAFT VC-515 Current Clamp Adapter AC/DC 1-1000 A, 1 mV/A Output, CAT III 600V VC-17605875

Electricians and industrial maintenance technicians often need to measure high currents without breaking the circuit. The VOLTCRAFT VC-515 current clamp adapter turns any standard multimeter with 4 mm safety sockets into a powerful AC/DC current meter up to 1000 A. Simply clamp around the conductor, connect the adapter to your multimeter, and read the current directly—no need to interrupt the circuit or use a separate clamp meter.

Why choose it

The VC-515 eliminates the need for a dedicated clamp meter when you already own a quality multimeter. It provides a safe, galvanically isolated measurement solution for high-current applications. The 1 mV/A output ensures straightforward conversion on any multimeter with a millivolt range. Its robust design and CAT III 600 V rating make it suitable for professional use in distribution panels and industrial environments.

Ideal use cases

• Measuring motor inrush currents and running currents
• Monitoring load currents in electrical panels
• Troubleshooting industrial equipment and HVAC systems
• Verifying current in battery systems and solar installations
• Educational demonstrations of current measurement

Good to know

The clamp adapter uses a 9 V battery, which is included, so you can start measuring right away. The 48 mm jaw opening accommodates large cables and busbars. For best accuracy, ensure the conductor is centered in the jaw and avoid strong external magnetic fields. The adapter is not intended for direct connection to mains voltage; always use it with a multimeter set to the appropriate mV AC/DC range.
