VOLTCRAFT MSL-503-2 Test Lead Set, 4 mm Safety Plug to 4 mm Safety Plug, 39 cm, 10 A, 1000 V, CAT III/IV, Black/Red, 2 Leads VC-18654460

Precision measurements demand reliable connections. The VOLTCRAFT MSL-503-2 test lead set eliminates contact uncertainty with spring-loaded lamella plugs that grip firmly in 4 mm safety sockets, ensuring stable readings even in high-vibration environments. Each set includes one black and one red lead, colour-coded for instant polarity identification.

Who is it for

Professional electricians, electronics engineers, and laboratory technicians who require safe, repeatable measurements on CAT III and CAT IV installations. Ideal for multimeter users needing short, low-resistance leads for bench work or field diagnostics.

Main features

Tips

Store leads loosely coiled to prevent insulation kinking. For high-energy circuits, always verify the multimeter's CAT rating matches the leads. Replace immediately if the plug insulation shows cracks or the lamella loses spring tension.
